There is also difference in Altcoin and Token. Ok, lets figure out.
Bitcoin is the first cryptocurrency(if it is correct to name it so) and it was made from total zero. It is coin. There are many altcoins - they are based on Bitcoin ideology and it's economic direction(I don't know how to say more understandable). Those of them who wrote their code from 0 are coins, others that decided to change the original chain are named forks. Those currencies that were launched on special platforms like Ethereum, NEO or others are tokens
