A coin in cryptocurrency refers to a digital asset that operates on its own blockchain. The most well-known example is Bitcoin (BTC), the first and most valuable crypto coin. Coins are used for various purposes such as transactions, value storage, and powering blockchain networks. Unlike tokens, which operate on existing blockchains, coins like Ethereum (ETH) and Litecoin (LTC) have their own infrastructures. As digital money, coins are decentralized, secure, and increasingly adopted in global finance. While promising, investing in coins comes with risks due to market volatility. Always research before diving into the crypto world
