There are two main types of digital currencies — tokens and coins.The main purpose of coins is the same as that of fiat money – you can buy services or goods with them, save them,
or almost anything else you can do with real money. The main thing about the coins is that they have their own blockchain.
The examples of coins is Bitcoin. It has its own blockchain that contains all transactions. So if you are looking to make a new coin, you might want to think about creating
your own blockchain as well.
On the other hand, tokens don’t have their own blockchain; they use existing platforms instead. An example of this is the ERC-20 token standard, which was developed by the Ethereum platform. With ERC-20 you can create your own token in a matter of minutes.
