During this time I also thought the price of altcoins depended on the second price. Why ? Because when we invest in new project ICOs, payment methods can use BTC or ETH. So if the value of the two decreases or increases, it certainly affects the price of the coins. Therefore, the price of altcoins has always followed the movement of the prices of bitcoin and ethereum. So I think like that and that's just my opinion about this. So sorry if wrong and irrelevant.
