to my knowledge Etereum follow the price of Bitcoin if I think Ethereum can not be separated from the influence of Bitcoin because Ethereum like silver and Bitcoin like gold.
YES.
This is absolutely correct as I strongly support this. Bitcoin is legendary as it rise and fall will also affect other altcoin. In addition, if you check the coinmarketcap you will see that Bitcoin is number one and I think it will remain like that for years to come till other projects in the Crypto Space prove otherwise.
