BTC Rally is followed directly by eth. Even if you don't move the price of other altcoin, eth will move. There is a specific price difference between Bitcoin and ETH. If the price of Bitcoin increases more and the price of Eth decreases, then it will be equal between the specified period.
If the price of Ethereum has decreased but Bitcoin has increased, then the price of Ethereum has decreased for only a moment. Going back up in my opinion. but if Bitcoin goes down a lot then everything will return to its old price.
Indeed, if the price of bitcoin has decreased, of course, it will affect the price of other coins and to be able to go up again is of course quite difficult and takes a long time,
I hope the price of bitcoin can continue to rise because that will make other coins follow the trend of bitcoin
