A Coin, or crypto coin, is a type of cryptocurrency that operates on its own independent platform, known as a blockchain, where all related transactions and operations are processed and recorded. The most common coin in the crypto space is the Bitcoin but there are other cryptocurrency coins available in the market today, collectively called as altcoins. These variants are conceived using the same open-source technology of the Bitcoin but with some modifications in the protocol's underlying codes, creating a new set of features that are different from Bitcoin.
