$1B bitcoins on the move: MtGox vs SilkRoad origin and BTC price impact discussed
Preamble: it seems that my post was censored and removed on bitcoin... from now I will only publish my articles on btc and crosspost it. Freedom and freespeech matter to me. -- This is the 4th post of a series of articles dedicated to investigate $1B worth of bitcoins (111,114 BTC/BCH/... BXX) that were dormant since 2014 and started moving actively. The BTC coins were originally located at this address (1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a).
The facts that part of this funds (>13%) have been transferred in the past month to Bitfinex, Binance and Bitmex exchanges is discussed here.
The origin of the bitcoins was originally discussed here.
A deep-dive into the wallet activity was discussed here.
Today I am writing a short update to discuss the origin of the funds and some events that could be related both to this wallet and yesterday's price crash. Wallet's origin This question has been discussed a lot by the crypto community in the past year. Here is a summary of the most probable hypothesis for the 1933p wallet's origin:
Wizsec, a prominent Bitcoin security expert, seems to be pretty sure that the wallet belongs to a MtGox hodler and early investor, who is not a DPR or a SilkRoad user, per his Twitter post: https://twitter.com/wizsecurity/status/1037030003068653569 Finally, Wizsec and I agree that this wallet is not CSW`'s wallet despite it is mentioned in several court documents. Wizsec spent a lot of time debunking CSW's ownership claims earlier this year: https://twitter.com/wizsecurity/status/968337084837781504 What do you think about this wallet origin? ` BTC price crash Also, I wanted to report some events that could be related to this 1933p wallet activity:
$100M USDT were transferred (reported by u/whalecheetah) while the 1933f wallet owner was in the process of transferring approximately the same amount to several exchanges.
10,000 BTC buy order was filed last night on Bitmex with 8,030 BTC transferred from a Bitfinex user wallet while the 1933p wallet owner transferred approximately the same amount of BTC to Bitfinex since August, 24th.
Binance's deposit problems on 2019 arise from an known, age-old, property of cryptocurrencies, generally known as "malleability". On Feb 5, 2019, Binance was reported to credit, for a second time, some Nano user deposits that had already been credited months before. The presumed reason is that they were upgrading nodes and replaying the block chain, and didn't turn off the deposit engine for this replay. When the new blocks were replayed, they somehow generated new block identifiers on Binance's internal servers (that is, these blocks were not relayed to Binance from outside Binance). These new block identifiers (for old blocks) triggered the deposit processor to create new internal deposits for user accounts, causing these accounts to get unduly credited with extra funds. This general crypto issue has been known for ages and it is surprising that Binance was susceptible to it. For example, the standard bitcoin transaction ID can be changed in a variety of ways without invalidating the transaction. This is called transaction ID malleability. If an exchange considers transactions with new transaction IDs as new deposits, they are susceptible to double deposits. The reason exchanges don't get caught by transaction malleability is that they judge new deposits by the transaction details and not the transaction ID, which can be changed. They also don't credit a user until the transaction has been confirmed a few times. While going down, MtGox famously blamed their problems on bitcoin transaction malleability (even though no one could ever verify these claims). Even though exchanges have adopted workarounds, the general property is potentially problematic enough that bitcoin introduced a new type of transaction identifier with the segwit fork to address this general issue of malleability. The nano protocol doesn't include the concept of confirmations, so counting confirmations to validate deposits can't apply. However, this dissimilarity doesn't mean that the basic problem of transaction malleability isn't known. And it underscores that the general practice of checking transaction details is much better than relying on protocol identifiers (like block or transaction IDs). My understanding is that nano 17.1 fixed the underlying source of malleability that caught Binance, but in upgrading to the fix Binance's deposit processor was running the old protocol and processed a few second deposits.

Want to relay my recent experience to help other canucks entering the cryptocurrency scene. I wanted to invest 100K in both main coins and some alt coins. Depositing that amount can’t be done using ETF/bank-transfeetc. – the only reasonably quick way is to wire funds. For wires, most exchanges have a percentage based deposit fee – something that makes absolutely no sense to me. Whether you wire 1K or 1MM, the amount of work for the exchange is identical, so it should be a flat fee. Deciding on an exchange is more complicated than that though: each one has their own rules for minimums/maximums, trading fees, supported coins, holding periods, and withdrawal fees. They also can vary greatly on the amount of time verification takes. One thing to note is that pretty much all exchanges don’t charge a fee for inbound crypto transfers. 2 months ago I signed up for 10 exchanges (Coinbase/GDAX, Binance, Coinsquare, Kraken, ezBTC, QuadrigaCX, Bitfinex, Gemeni, Bittrex, Poloniex) and was verified on 7 of them (I’m still in queue for Gemeni, Bittrex, and Poloniex). Verification times gave me what I thought was a decent indicator of the level and quality of support I would receive. Of these exchanges, some have what I believe to be relatively high trading fees (Gemeni .25%, Bittrex, .25%, ezBTC .30%, QuadrigaCX .50%) vs lower maketaker fees (GDAX 0/.3%, Binance .1/.1%, Gitfinex .1/.2%, Coinsquare .1/.2%, Kraken .16/.26%). Still others have high percentage based wire fees. And finally, there’s a big disparity between withdrawal fees: free on some exchanes, vs fixed rate based on the coin for others, vs Coinsquare’s insane fixed 0.0025 BTC regardless of what coin or the amount being withdrawn. So here are some observations on the exchanges. Please note that the below is not a reflection on any of the people who work at the exchanges. I’m sure they are working as hard as they can and are doing their best. It’s just my experience. It’s also not financial advice. Also, I’m only human so feel free to offer corrections or better advice. Coinsquare: amazingly fast verification time, and for very large deposits seems to likely be the best option as they will let you speak to a human being by phone and will waive the deposit fee (I didn’t know this until later though). I excluded them because of their high 0.5% percentage based deposit fee and their crazy high withdrawal fee. They also only have support for 6 coins. QuadrigaCX: I had a terrible initial experience with QuadrigaCX’s support, so I immediately excluded them. They have high trading fees and there are many complaints of support tickets being ignored or having extremely lengthy wait times. They have a crazy high 1% percentage based CAD wire fee, but offer free USD wires. Note that they only support wires for large amounts. GDAX/Coinbase: Loads of good reviews, but only has support for 4 coins. Seems like they also don’t have a fee for crypto withdrawals. You also can’t seem to wire CAD or USD funds directly to GDAX. I think you may have to wire USD funds to Coinbase and then transfer them over to GDAX (for free). Kraken: I created an account but the verification page just appeared blank for me. After a few days, their support team got back to me telling me that they had a bug and that I needed to create a new account using a different email address and try again. That worked. I decided to use them as they seemed like the best all-around alternative. I was impressed with their support response (they gave me an answer that worked and responded in days as opposed to weeks), they offer a no-fee inbound CAD wire, support 16 coins, and have low (though not free) crypto withdrawal fees. They have also been around a while and have a good reputation (They were picked to handle MtGox claims). Wiring funds to them was a hair-raising experience though. You basically need to send your funds to an unknown bank in Tokyo, Japan. Kraken also has two slightly different sets of wire instructions: one that is on their website, and the other that their support folks send out. Only one of them mentions that you should tell your bank not to use an intermediary that will convert your currency. If you do things properly, and are lucky, you end up only paying ~$40 in fees. But chances are, you don’t, and end up paying 4%! (see https://www.reddit.com/BitcoinCA/comments/7rd6k8/fees_when_sending_to_krakencom/). You also have no idea how much the fees will be until the money finally shows up in your account. That’s tremendously unsettling. Luckily my bank branch manager was familiar with crypto currency wires and helped me do things properly. But, the wire took over 2 weeks to show up (Jan 18th), and Kraken support is so overloaded that they didn’t’ respond, despite me escalating my support ticket several times. I eventually had to resort to a reddit post to get a response to my support ticket. I gave support my wire receipt and answered lots of additional questions to help them try to “locate” it. Perhaps the worst part of my entire experience was that while my wire was being located, the entire crypto market tanked by 50%...and no one would respond to my support ticket…I felt helpless. A Kraken support rep a few days ago said that they are handing >50K new user registrations per day and have >20K new support tickets per day. I feel they should turn off new user registrations until they are capable of servicing existing customers. This is what their competitors have done. I found it disheartening to learn that the only way to get a response to my support ticket was to complain via social media --- many others have found the same. While I was waiting for my wire to appear Kraken had a >48h outage. Prior to the outage, the site was almost unusable as you’d receive constant 50x errors (I found this out prior to wiring my funds). After the outage, I find that their site is still barely usable. Pages take 10-15 seconds to load and when they do load many times they display errors so you have to continually retry until things work. At the end of the day though, they did come through for me: my wire arrived safely. So with my funds in Kraken, I tried to use them to purchase crypto. But no matter what I tried, none of the CAD dollar trading pairs would appear. I logged out and back in a few times and 15 minutes later, it suddenly started appearing. With the flakiness in Kraken’s platform, I had no choice but to transfer everything to a more stable and faster exchange: Binance: These guys have their shit in order. Super simple site navigation once you get used to it, fast verification times, blazingly fast website and trading engine, more than 50 coins supported, etc. But, they don’t support fiat – you must use one of the other exchanges to buy crypto with fiat and then transfer in your crypto. Gotta say it again: everything is super fast. Not just the page loads, but also trading, email confirmations, and withdrawals. Trading takes a bit of getting used to as you aren’t really buying or selling crypto…you are instead “trading” one crypto coin for another. Depending on the coin you want to purchase, you might have to trade your coin for BNB (binance’s own coin) and then trade BNB for the coin you desire. Be Your Own Bank: One final word of advice. Binance is awesome, but don’t trust anyone as despite everyone’s best intentions: no matter how secure a platform is, it can and will be hacked. As soon as you have done your shopping, transfer your coins off to your own wallet. This is why withdrawal fees are important. You might be asking: in hindsight, if I had to do it all over again, what would I do differently? To wire CAD funds I would try to use Coinsquare if it’s a big amount (after re-reading other people’s recent reviews). For USD wires, I might try using Gemeni, but I still haven’t been verified by them and have been waiting for almost 2 months. Before using either I would re-test how long it takes for a support ticket to be responded to. If you do wire funds, don't wire an exact round amount like "10,000.00", instead I would wire "10,070.45" so that it's easier to locate if things go wrong. Once the account has been funded I wouldn’t hesitate to transfer everything to another exchange if I wasn’t happy with the platform, the number of coin offerings, or quality of service I was receiving: you can always come back when things improve. Things change so quickly so not sure how helpful this will be…just wished I had known some of the above before starting.
Okay, so when the issue about suspended XLM withdrawal from Binance arose, I don't think much about it. After all, just last month Polo has the exact same issue and they fix it in about a week. Since nearly all exchange use only 1 wallet for ALL their users, you can check their XLM balance and most of the time there'll be millions if not billions of XLM sitting there, easing yourself from worry of being mt goxed. So, just today out of curiosity I decided to check binance stellar wallet...Now, there's only about 100K XLM sitting on their wallet. You can check it by yourself, and compare it with other exchange wallet:
Now, I know that this doesn't mean that binance is mtgoxing us. A lot of possible scenario that I can think of is that they have another wallet to store XLM safely, or that they decided to create a new wallet and move the fund there. Or maybe they decided to apply 1 wallet per user policy, and begin redistributing user's XLM to each their own wallet (ala how XRP wallet works in Polo). It'll be nice though if someone from Binance can confirm what exactly happened, and whether our funds is still safe there or not, since the low amount of XLM on their public address kinda make me worried. There's no way an exhange with more that $100 million of XLM volume only has around 100K XLM on their wallet. EDIT: Apparently they have another wallet here and been transferring all of our deposit to that wallet. Why they decided to use separate wallet, I don't know though
Hello! My name is Inna Halahuz, I am a sales manager at Platinum, the largest listing service provider for the STO and ICO projects. We know all about the best and most useful STO and ICO marketing services. By the way, we developed the best blockchain platform: [Platinum.fund] (https://platinum.fund/sto/) We also created the UBAI, the unique educational project with the best and most useful online courses. We not only share our knowledge but also help the best graduates to find a job! After finishing our courses you will know all about crypto securities, ICO and STO advertizing and best blockchain platforms. What a Blockchain Wallet is? What is its purpose? Find the answer after reading this article. Public/Private Key The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver. Accessing wallets Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals. Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets. Types of Wallets & Storage Methods The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners. Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens. Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples. Hardware wallets — LedgeTrezoAlternatives Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers. Paper Wallets Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper! Real World Historical Examples of Different Wallet Types Web Wallet: Blockchain.info Brief mechanism & Security Blockchain.info is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by blockchain.info has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops. Neon Wallet The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as https://bitcoinpaperwallet.com/ and https://walletgenerator.net/. They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible. Real World Example — Poor Practices MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets. In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes. Case Study: Good Practice Binance, the Attempted Hack During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “binance.com”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt. Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange. Hardware Wallets Advantages and Limitations We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations. Paper Wallets Advantages and Limitations Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever. Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose. You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait. How to Monitor Funds There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. Blockchain.info is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including nanoexplorer.io for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor. That’s not all!
