Bitcoin₿ and crypto directory: find the right service

What we examine before presenting a crypto service

A familiar brand or lengthy feature list is only a starting point. We look at what a service does, what it costs and who can use it. Reviews cover the checks to make before signing up, including limitations that may affect your choice.

Reviews explain the scope of the analysis. Where practical testing is included, its conditions should be clear. Documentary research is not a security audit.

Why Bitcoin has a distinct place among cryptocurrencies

Bitcoin is a useful starting point for understanding digital transfers, transaction verification and managing your own access to assets. These six points explain the network and the questions it raises.

Market context

Cryptocurrency prices: leading assets by market capitalisation

Check Bitcoin, Ethereum and the other assets shown below. Market capitalisation compares their size, without measuring quality or future potential. Prices are in US dollars and data is updated once a day. The full ranking lets you search for an asset and compare changes over different periods. Open an asset for its detail page.

Looking for a place to buy or sell? Explore the exchange category and its reviews. The displayed price is a reference, not the final price of a purchase on an exchange.

Eight terms to understand Bitcoin and crypto

Wallet, private key and address appear from your first transactions. Knowing the differences helps you understand the tools and which information to share.

01Blockchain

A transaction history organised into blocks and shared across a network. Validation rules and decentralisation differ between blockchains.

02Mining

Bitcoin miners use hardware and electricity to help add blocks. They may receive the block reward and transaction fees. Not all cryptocurrencies use mining.

03Wallet

A tool for managing access to crypto and preparing transactions. You may control the keys yourself or use a provider that manages them.

04Private key

Secret data used to sign transactions and control associated funds under network rules. Never share it or your wallet recovery phrase.

05Public key

Data mathematically related to a private key, used to verify signatures. It is involved in receiving and spending mechanisms but is distinct from an address.

06Address

An identifier for receiving an asset on a particular network. Check the asset, network and destination before sending; addresses are not automatically interchangeable between networks.

07Satoshi

A unit of Bitcoin: one BTC contains 100 million satoshis, allowing fractions of bitcoin to be expressed and used.

08Cryptocurrency

A digital asset whose transactions use cryptographic mechanisms. Projects differ in purpose, operation and governance; some rely on centralised issuers or providers.
