and is it true that he threatens the existance of bitcoin ?
Ethereum is an altcoin which is one of the rivals of bitcoin. Compared to bitcoin, ethereum has a lower value. Just like bitcoin, it is used in different transactions in the internet. Also, it is used by application developers to pay transactions fees and services in ethereum network. So, ethereum is a cryptocurrency just like bitcoin but has a lower value but some miners work to earn this and not bitcoin.
