With due respect, I think you should at least make more explanation to justify your claim, because most people knew bitcoin is part of crypto currency but you said bitcoin itself is crypto currency. Do mean crypto is bitcoin as well or bitcoin is crypto like ethereum and all other coins?
I'll explain for him.
Cryptocurrency is a digital Currency. (Ex. (Litecoin, Ethereum , Bitcoin etc.)are all Cryptocurrency
Bitcoin as he said is a cryptocurrency and Bitcoin is the first and leading cryptocurrency today. In regarding with blockchain, it is a network where these cryptos are processed digitally and encrypted.
Correct me if I'm wrong.This is my own understanding.
