Cryptocurrency is a digital currency based on blockchain technology that enables peer-to-peer (C2C) transactions.

Bitcoin, Ethereum, Binance Coin, and Tether are currently the leading cryptocurrencies by market capitalization.

Cryptocurrencies can be accessed in two ways: in a cryptocurrency wallet or on an exchange. Although people often say that cryptocurrencies are "stored" in a wallet, they are actually stored on the blockchain.

Cryptocurrencies have several main characteristics, including decentralization, high transparency, and immutability.
