For anyone who wants read the first post, please click "3 types of Blockchain".

The 2 types of Cryptocurrency is Coins, Tokens.

Cryptocurrency Coin operates on its own platform which called blockchain, has its own balockchain protocol.

Most of altcoins are variants of Bitcoin, built using Bitcoin''s open sourced code with changes to its codes.

There are other other altcoins created their own blockchain platform and protocol, like Ethereum Ripple, NEO, Dash.

Cryptocurrency Token, on the other hands, is created on existing blockchain platform since it does not have its own blockchain.

The most common blochkain token platform are Ethereum, tokens that are built on it are known as ERC-20 tokens.

Tokens can also be divided into smaller values like Coins. The ERC-20 contract allows for specifying up to 18 decimal places for token creation. 

Tokens are defined 4 types as security, asset, utility or payment by Swiss Financial regulators FINMA.
