Bitcoin Wallets: How to choose a BTC wallet in 2021




Bitcoin Wallets :

The bitcoin wallet is one of the most actively developed applications in the Bitcoin ecosystem. There is fierce competition here, and there may be new wallets under development, but there are also several wallets from last year that is no longer actively maintained.


Many wallets focus on specific platforms or specific uses, some are more suitable for beginners, while other wallets provide features for advanced users.

Choosing a wallet is very subjective and depends on the use and the user’s expertise. Therefore, it is impossible to recommend a specific wallet brand or item.

However, we can classify Bitcoin wallets according to their platforms and functions, and provide some suggestions for all different types of wallets.

Even better, moving money between Bitcoin wallets is easy, cheap, and fast, so it’s worth trying several wallets until you find a wallet that meets your needs.

According to the platform, bitcoin wallets can be classified as follows:

1. Desktop wallet :

The desktop wallet is the first type of bitcoin wallet created as a reference implementation, and many users run the desktop wallet to achieve its functionality, autonomy, and control.

Running on general operating systems (such as Windows and macOS) has certain security risks because these platforms are often insecure and improperly configured.

  • Bitcoin Core:

    Bitcoin Core:

It is a Bitcoin client that implements a full node, which forms the scaffold of the entire Bitcoin network. Bitcoin core has extremely high security, privacy, and stability. But it has fewer features and will take up a lot of disk and memory space.

  • Bitcoin Knots:

Many of Bitcoin’s nodes are a complete Bitcoin client and have established the backbone of the Bitcoin network. The client provides a high level of security, high privacy, and high standard stability.

Bitcoin Knots

Clients contain more advanced features than Bitcoin Core, but these clients are not well tested. The client will take up a lot of disk space and computer memory.

2. Mobile Wallet:

3. Online wallet :

The web online wallet is accessed through a web browser and stores the user’s wallet on a server owned by a third party.

This is similar to webmail because it relies entirely on third-party servers. Some of these services operate using client-side code running in the user’s browser, which can control the bitcoin key in the user’s hand.

However, most people need to compromise between safety and convenience. It is not appropriate to store large amounts of Bitcoin on third-party systems.

Web online wallets store your private keys online, and they are encrypted with user-defined passwords. The security of the web  online wallet is poor, but it can be obtained from any networked device.

  • Green Address:

All Bitcoin-related operations are performed through dedicated hardware. These wallets are considered very secure and suitable for storing large amounts of Bitcoin.

  • Trezor:


TREZOR is a hardware wallet, which has high security without sacrificing convenience. Unlike cold storage, TREZOR can realize transactions when connected to an online device. This means that it is safe to use Bitcoin even when using an insecure computer.

5. Paper wallet

The key that controls Bitcoin can also be printed for long-term storage. Even though other materials (wood, metal, etc.) can be used, these are also called paper wallets.

Paper wallets provide a low-tech but highly secure method for long-term storage of bitcoins. Offline storage is also often referred to as cold storage.

Another way to classify Bitcoin wallets is through their degree of autonomy and how they interact with the Bitcoin network:

6. Full node client :

A full client or “full node” is a client that stores the entire history of Bitcoin transactions (every transaction per user), manages the user’s wallet, and can directly initiate transactions on the Bitcoin network.

The full node handles all aspects of the protocol and can independently verify the entire blockchain and any transactions. The full-node client consumes a lot of computer resources (for example, more than 125 GB of disk, 2 GB of RAM), but provides completely autonomous and independent transaction verification.

7. Lightweight client:

A lightweight client, also known as Simple Payment Verification (SPV) client, connects to the Bitcoin full node (mentioned earlier) for accessing Bitcoin transaction information, but stores the user wallet locally, and Create, verify and transmit transactions independently. The lightweight client interacts directly with the Bitcoin network without an intermediary.

8. Third-party API client:

A third-party API client is an API client that interacts with Bitcoin through a third-party system of an application programming interface (API), rather than directly connecting to the Bitcoin network.

At this time, the wallet may be stored by the user or a third-party server, but all transactions need to go through a third party.

Combining these classifications, Bitcoin wallets can be divided into several groups. The three most common divisions are desktop full clients, mobile lightweight wallets, and online third-party wallets.

The limits between various classes are frequently obscured, and numerous wallets run on different stages and can communicate with the organization in various manners.
