Bitcoin is a digital currency, so you need to use some software to use your coins and make / receive payments. The community of the digital currency calls such programs "bitcoin-purses". To date, there are several different purses, each of which works differently than the other, and differs from other wallets by its principles and philosophy. It's important to choose the wallet that's right for you. In this review we will tell you about a few wallets so that you can choose the most suitable. We compared the usability and security of hardware wallets.

Airbitz
Airbitz is a very convenient bitcoin-purse, you can work with it almost intuitively. It is suitable for Android and iOS devices. This application offers many different functions, besides the basic set (sending and receiving bitcoins), for example, hierarchical deterministic wallets, where the parent key can generate and manage several child keys. This is an excellent addition for more experienced users, which can be used for various purposes, mainly in the business environment.

With the help of the application, you can exchange bitcoyne for fiat currencies. Also, the app offers you a list of companies nearby that take bitcoyne. Thus, it is easy to choose a store, a cafe or a restaurant in which you can pay bittocks.

If you need a multifunctional, well-integrated wallet, which is great for daily use, Airbitz is what you need.

Coinomi
Coinomi is a mobile wallet for Android, but it is already planned to launch a similar application for iOS. Coinomi is described as a free, safe, affordable, purse for a range of assets and coins. It supports more than 60 tokens / altkones, so you can expand your investment portfolio with alternative crypto-currencies and digital assets, in addition to bitcoins. Developers of the application constantly try to expand the use of key altcoyins and tokens, which, in their opinion, deserve attention.

Coinomi is good not only for a wide choice of currencies, but also for the ability to convert various altkones, thanks to a strategic partnership with ShapeShift.

The pride of Coinomi is also confidentiality and security. Personal keys never leave the user device, where they are stored, protected by reliable cryptography. The company's management assures that its servers do not associate IP users with their addresses, and that all requests are reliably anonymous.

Under the terms of the software agreement for Coinomi software, the source code can be obtained from GitHub.

And for a trader working with many currencies, and for a regular user who wants to always remain anonymous, Coinomi will exactly fit.

Copay
Copay is positioning itself as a "reliable, publicly available bitcoin-wallet." Like a joint settlement account, the Copay wallet can unite several users through a multi-signature system. Simply put, in order to conduct a simple bitcoin-transaction, only one client's secret signature is needed. And Copay provides an opportunity to create wallets with several signatures, in which the assets are in a group account and they can be spent only when all participants agree to the transaction and confirm it with their keys. For example, you can create a purse with a multi-signature for the child's savings account, and set such parameters that the child will need permission from the parents (one or both) to withdraw or use the money.

This type of wallet can be used for various operations and situations, and Copay makes the process of keeping a common wallet absolutely convenient and safe. Of course, Copay has both individual wallets for personal assets and much more, for example, hierarchical deterministic backup, where you only need to deploy the purse from your backup once to get guaranteed access to all of your funds.

Copay has open source code from both the client side and the server side and is published under the MIT license. It supports many platforms, including iOS, Android, Windows Phone and other operating systems. Many people like Copay for the fact that it's a "pure bitcoin-wallet", and not a service with account records, which frees you from having to register with the service and only then have the opportunity to use your wallet.

Now Copay only supports bitcoin-wallets and has no plans to connect any altcoyins. Copay is the ideal option for those who need a common bitcoin-purse, or for those who are looking for simplicity and functionality.

Electrum
Electrum - this is one of the most famous and most popular on the part of users bitkojn-a purse. The creation of the application was initiated by Thomas Vogtlin in November 2011. Electrum is a free application released under the MIT license and it is actively developed by developers around the world. Electrum is considered a thin bit-client, that is, it uses distributed servers to manage the most complicated parts of the bitcoin protocol, for example, translating transactions and indexing the block. With such technologies, all secret keys are on your computer, but at the same time, there is no need to completely download the block from the network. This saves a lot of disk space.

Electrum is known as a "forgiving purse"; it provides the ability to generate a deterministic wallet. When registering a new wallet, Electrum gives the user a 12-digit mnemonic phrase (seed), with which the user can restore it if necessary in the future. This length is completely safe; 138 bits of entropy provides protection, similar to the reliability of the one that is present in the private key. If you lose the key to your wallet, you can easily restore it by just entering that phrase.

Electrum is quickly and easily installed on any modern operating system. But it can have some difficulties with its use. Electrum is more repulsive from functionality, not from user experience. It uses some aspects of the lower protocol level, so for a technically unprepared user, Electrum may not be the best choice.

Electrum transparently integrates with Trezor, so the owner of this bundle can use Electrum's translation functionality, and do not worry about the private keys from the addresses stored in the Trezor b / roll-safe.

If you need a simple, thin and functional bitcoin purse with a good track record, Electrum is an excellent option.

Mycelium
Mycelium, he calls himself "bitcoin-purse by default". It offers an excellent user interface, and tries to "make bitkoyn easier for everyone." Wallet is only suitable for mobile devices and supports both Android and iOS. It offers not only basic functions, but also a number of in-depth features for more experienced users, such as hierarchical deterministic wallets, special accounts and cold storage. Also, in Mycelium it is possible to have several wallets per user, which makes identity management less confusing.

Mycelium is released under a software license from Apache 2.0 and MS-RSL. The source code is on GitHub. Once Mycelium was launched (and it is one of the first hardware wallets), it became one of the most popular applications in the crypto industry. Mycelium works with a large number of third-party firms, including exchanges and technological blockbuster companies, in order to integrate their services. So, Coinapult, for example, is responsible for the security and ease of use of the bitcoin platform. The main feature of this platform is the ability to "lock", using which, you can specify any number of bitcoins in relation to any currency (US dollar, euro or British pound), so that you always have a certain amount of money in Fiat on your account. This function has already been included in Mycelium and it is useful to everyone, who wants to use bitcoin as a currency, and not as an invest-asset. However, this function should be used only if you plan to fix the value of the currency for a long period of time, since the locking process can be quite slow, you can lose a decent amount of money if you block and unlock often, even if you expected to profit from it .

In addition to a huge number of other services, Mycelium makes individual trading more simple, because with the application it is possible to quickly and without problems exchange Fiat for bitkoyny and vice versa. Since this function is embedded in the application, the trade and payment are much easier and more convenient.

Mycelium also integrates with Trezor, allows you to send and receive funds to Trezor's addresses.

Mycelium plans to grow to the level of a full-fledged financial management package, which allows unchecked control of digital assets. Need an open source wallet, a wide range of functions, perspective thinking and the possibility of financial management? Then Mycelium is a great choice.
