Money Loves Security And So Do Cryptos: A Brief Guide Down Crypto Wallet LaneSince time immemorial people have been keeping their money and valuables in safe places. Be they purses, clay pots full of coins buried in their backyards or treasure chests hidden in caves with piles of bones strewn around to keep unwanted visitors at bay, they means conceived for safekeeping hoarded valuables are just as creative as they are limitless.
The advent of cryptocurrencies as a new class of valuables and assets instantly spawned the need to keep them safe from the clammy hands of criminals. The logical solution was to develop wallets that would be used to keep cryptos safe. As a result, a multitude of wallets have emerged offering all kinds of added services to their users while remaining means of storage at heart.
There is a huge variety of wallets available: Coinomi, GreenAddress, Blockchain.info, Atomic, Exodus, Jaxx, Electrum, Copay, Bread, Airbitz, Armory, Mycelium, Blockchain Wallet and dozens of others, each offering their services to suit any taste.
Types Of WalletsThere are several types of wallets available to users and everyone must decide for themselves which one suits their needs best.
Hardware wallets: These are the most secure and reliable wallets available, since they are not connected to the internet at all. Hardware wallets are like flash memory cards that store the user’s cryptocurrencies and access offline. A bright example is the Trezor wallet, which is deemed to be impermeable to hackers. Unless the user loses the device itself, it is safe to assume that the cryptos will stay on it indefinitely and no one will ever gain access to them.
Online, Web or Hot wallets: These are online services, or online wallets that offer to store the user’s cryptos online with direct access to the internet at any time. In essence, online wallets are online accounts in which users store their funds. The risks are very high, since exchange wallets are routinely being hacked and the cryptos stored therein stolen.
Desktop wallets: Desktop wallets are software programs that can be downloaded and installed on a PC and will only be accessible from the device they were downloaded onto. The risks are the same as with hot wallets and another added inconvenience is that loss of the device or loss of access to it means loss of all cryptos stored on it.
Mobile wallets: Mobile wallets are software programs that can be downloaded onto a mobile device, such as a phone or a tablet. There are wallets for Android and iPhones and all of them bear even greater risks than hot wallets. Since mobile devices are susceptible to theft and a variety of viruses, it is extremely risky to store cryptos on them. Though access to the cryptos without private keys is impossible, unless the user stores them on the device, loss of all cryptos with the mobile device is guaranteed.
Paper wallets: Paper wallets are offline cold storage for cryptocurrencies. This is by far the safest means of storing cryptos, which includes printing the public and private keys on a piece of paper and storing it in a safe place. The keys are printed in the form of QR codes for convenience. With paper wallets, the user has complete control over their funds and the only risk lies in losing the piece of paper with the keys.
Other types of wallets: Apart from the five main types of wallets, there were attempts at creating other types of services, such as atomic wallets using atomic swap technology and even combinations of mobile/hot/cold wallets. Despite limited success, hybrids models of wallets did not become popular.
Main Pros And ConsWhen looking at wallets and their main advantages and disadvantages, it is easiest to speak of the division between cold and hot wallets.
When speaking of cold wallets, such as the Trezor Bitcoin wallet and Ledger Nano S or X, the same issue will be observed, and that is the fact that such wallets can be physically lost. Though anyone who ever finds them will never be able to gain access to the stored cryptos without the private keys (unless they are pasted on the device), loss of all cryptos on the device is guaranteed. In addition, cold wallets can be difficult to install and are inconvenient for frequent use.
Hot wallets are far more susceptible to risk than their cold counterparts. Though hot storage is much faster and convenient with a wide variety of options from Coinbase to Blockchain.info, the risk of cybercrime runs high. Mobile or desktop storage is also considered to be hot storage and is also risky, if the device is damaged or destroyed.
Bitcoin ProblemsBitcoin, as the firstborn cryptocurrency, was born with a number of defects. One of the main problems of the king of cryptos is the yet unsolved scalability problem. This refers to the limit on the amount of transactions the Bitcoin network can process due to the limited size of and frequency of blocks in the Bitcoin blockchain.
Said problem poses some difficulties to all Bitcoin users and leads to what is known as backlog in the blockchain. The backlog leads to long queues of transactions in the system. With the average transaction time in the Bitcoin blockchain being around 7 transactions per second and the theoretical maximum standing at 27, it is not difficult to understand how long users of the blockchain have to wait for their transactions to pass in times of heightened demand – the time is in the hours and sometimes even days.
Bitcoin Wallets ReviewSince Bitcoin is the most popular cryptocurrency on the market, it is logical to judge wallets by their support of the first cryptocurrency. As such, the following will be a brief review of some of the best and most popular Bitcoin wallets on the market.
Online Bitcoin Wallets
Online or web wallets are the most popular ones out there and the best Bitcoin wallet overall is widely considered to be Blockchain.info, which is easily accessible and convenient for everyday use with good security. As an anonymous Bitcoin wallet, Coinbase follows in the lead with its ability to store a multitude of various coins, but with the same security risks that are inherent to all hot wallets.
Android Bitcoin Wallets
Android is the most popular mobile system in the world and plays host to a number of good mobile wallets. The best Android Bitcoin wallet is widely considered to be the Electrum Bitcoin wallet with its excellent reputation, good security and convenience. Though Electrum has some occasional glitches, they are never critical. Another excellent wallet for Android is the Coinomi wallet with its support for a wide variety of cryptos and excellent user support, which even allows for restore options using special phrases. Coinomi has its issues as well, such as occasional exchange glitches, but the many pros outweigh the cons.
Bitcoin Hardware Wallets
The undisputed leaders as the best hardware wallets for Bitcoin are Ledger Nano X and S, Trezor T and Trezor One, and Keepkey. Bitcoin hardware wallets are comparable in their security, accessibility and usability. The difference is mainly in the price, which ranges from $165 for Trzeor T to $59 for the Ledger Nano S model. In fact, the Ledger Bitcoin wallet is often called the king of hardware wallets. The KeepKey Bitcoin wallet is the in the top three hardware wallets as a convenient and stylish device. Though KeepKey supports over 40 assets, it still lacks coin support.
Bitcoin Wallets For iPhone
iPhone’s iOS system is the second most popular for mobile devices in the world and has support for some good wallets as well. The best iOS Bitcoin wallet for iPhone is considered to be the Abra software, which offers credit card support for topping up crypto balances and a good user interface, which is even more oriented at exchanges. The next software is Edge, formerly known as Airbitz. The Edge wallet is best known for high security and good user-friendliness along with multi-currency support.
Bitcoin Wallets For Windows
Bitcoin wallets for PC are very popular and Windows is leading the way with some excellent offers for wallets. Atomic is by far the most advanced and the best option for Windows users as it offers Atomic swaps technology as its basis. The application offers a wide variety of operations and supports over 300 cryptocurrencies. Exodus is the second most popular choice as a desktop only wallet with support for Bitcoin and many other altcoins. Exodus offers its users a good interface and it is free for use.
Bitcoin Wallets For Mac
Since Atomic and Exodus are cross-platform wallets, they can be used on Windows and Mac. Apart from them, there are also Jaxx and Electrum, which can be used on Mac. Jaxx is a multi-currency wallet with support for around 40 cryptos and has a PIN feature. In addition, Jaxx is free for use. Electrum is one of the oldest desktop wallets and is a lightweight wallet that does not require the full blockchain to operate, meaning less storage needed for its operation. The wallet requires a PIN and is essentially a desktop bank with good security and usability. Electrum is also a Bitcoin wallet for iPad, since it can be used on mobile platforms.
Bitcoin Paper Wallet
Since storing cryptos online on exchange or hot wallets or even on devices is risky, it is oftentimes more convenient to use a simple printer to print out the keys and store them. BitAddress offers a convenient and easy to use, step by step guide to creating a paper wallet with the added benefit of sleeping in peace, known that nothing and no one will ever threaten your Bitcoins.
ChecklistWhen embarking on the journey of creating your first wallet, think well of which type to use. The type will depend on the priorities that stand before the user. If security is paramount, then paper or cold storage wallets are the go-to solution. If frequency of use is the name of the day, then hot wallets and their inherent risks are the best way to go.
The most frequent questions related to wallets are how to add money to a Bitcoin wallet and how to set up a Bitcoin wallet. Both questions have no single answer, as each wallet offers its own instructions on how to top up balances and how to set them up. Therefore it is recommended to study all instructions carefully prior to operation.
Either way, there is no silver bullet and some features will have to be sacrificed in deciding how to store cryptocurrencies. The one thing that is constant is the need to store Bitcoins and cryptos and make use of them.

All cryptocurrency transactions are based on the control of two important numbers: public and private keys. Public keys facilitate the transfer of crypto; private keys, their receipt. These keys are stored and secured through digital wallets, the software through which users have access to their digital assets.
There are two main models of cryptocurrency wallets: those that don’t allow users to control their private keys and those that do. The first model of wallets host users’ private keys on a centralized server, which facilitates transactions. In the second model, users hold their own private keys and are able to send and receive tokens without the consent of a third party.
So just how important is it to directly control your private keys? We’ll answer that question today, and review some of the best wallet options that allow you to do that.
Private keys: What they are and why they matterPrivate keys are randomly generated secret numbers that link a user to particular cryptocurrency assets. Coins can be transferred to other blockchains only by accessing a wallet’s private keys. For this reason, it is extremely important to keep private keys secure and confidential. Matt Miller, a Bloomberg TV host, demonstrated this lesson to the world when he briefly showed his private key QR code on-air and had his funds immediately stolen.
In one model of wallet, a third-party retains control of the private keys. This model is typically described as the crypto version of a bank. The user is the owner of the funds but relies on the wallet’s server to execute transactions. However, this comparison fails to recognize key dangers inherent in third-party management of crypto funds.
Crypto wallets, like bank accounts and any other internet-connected account, are at risk of being hacked. Unlike banks, however, crypto projects are not legally obligated to refund account holders their funds in the case of a security breach. For this reason, keeping funds in a wallet for which you don’t control the private keys is significantly riskier than storing fiat currency in a bank.
User-owned private key wallets offer a much stronger option in terms of security. No one has control over your funds except you. That means that if someone hacks the server hosting your wallet, your funds are secure. It also means that you can’t have your funds stolen if the wallet’s leadership “loses” the private keys (yes, that has happened).
Always remember that private keys unlock full access to digital funds. Opting for wallets with user-owned private keys ensures that you maintain control over your funds and do not rely on a third party to make transactions. Here, we picked out some of the most trusted solutions that allow full user-control over private keys.
Coin WalletCoin Wallet is an excellent solution that allows you to directly conduct blockchain transactions and access tokens. You can export your private keys, and the wallet does not have access or oversight over your operations within the software.
Coin Wallet is suited to the needs of both beginners and professional crypto users. It comes as free software with simple and streamlined interfaces in both mobile and desktop versions. The wallet supports any ERC20 and ERC223 tokens, including Bitcoin, Litecoin, Dogecoin, Bitcoin Cash, EOS, Ripple, Stellar, and Ethereum.
Of all the wallets on the market, Coin Wallet offers one of the most exhaustive collections of coins. Currently, there are more than 20,000 supported cryptocurrencies. The app gets bonus points for convenience, providing two built-in exchanges: Changelly and ShapeShift.
BlockchainIn 2011, Blockchain wallet pioneered the niche of online wallets. It remains one of the market leaders in wallets offering user-controlled keys. Currently, the company has over 41M wallets and more than $200B in transactions have been made on it since its start.
The mobile app is available in multiple languages and offers a built-in exchange for fast trading. Interfaces are very easy to follow and intuitive. The major drawback of this veteran wallet is that it supports just 5 coins: Bitcoin (BTC), Ether (ETH), Bitcoin Cash (BCH), Stellar (XLM), and USD PAX (PAX).
ExodusExodus comes as a download for desktop or mobile. In addition to giving you control of your private keys, it also allows you to export them, as well. Plus, as an extra security measure, it never stores private keys on the server.
This wallet may not suit the needs of all users, as there is no web version and English is the only supported language.
The app lists 100+ crypto coins and offers ShapeShift as a built-in exchange.
ArmoryArmory wallet is a great choice for users who want a simple storage option for their crypto assets. It offers some offline functionality, as well as free cold storage. It also lets you back up private keys (a QR code) on paper or create a multi-signature wallet. The latter option is particularly useful for businesses.
A major drawback of this wallet is that it is the least user-friendly option. Users need to have some basic knowledge encryption and software set-up. In addition, sending digital assets with Armory is less convenient than competitors and it doesn’t offer any built-in exchanges.
Bitcoin CoreLaunched by the Bitcoin project, Bitcoin Core has a simple interface and is compatible with Mac, Linux, and Windows. It allows users to check the full node of Bitcoin transactions, i.e. download the entire blockchain. Therefore, it might take some time to download the full blockchain and set up your wallet.
A drawback of Bitcoin Core is that it’s large: you must have at least 200GB free disk space for this software, and system requirements constantly increase as the full Bitcoin network node grows.
As its name suggests, Bitcoin Core supports only Bitcoin. If you plan on trading and using only Bitcoin, this wallet is a great choice. Because you keep the full node on your computer, you don’t need any third parties to verify transactions. Sending or receiving coins here is very simple, and you are directly connected to the full Bitcoin network node. The fees are decided on by user votes.

Trust no oneBitcoin is trust-less, use it that way
Use unique strong passwordsUse a secure password manager for your logins (I use pwSafe)
Use good antivirus protection (I use Bitdefender on mac)Keep it up to date
Consider physical securityIf you store your 2nd wallet backup in the glove compartment of your car, and your car gets stolen, your bitcoins may be gone too…
Keep backupsWhenever I create a new wallet I create 2 full paper backups including the seed and any other security (password, pin, etc…).
