I think it's natural, because when the price of bitcoin goes up, the altcoin will go down. and after the bitcoin price stabilizes, altcoin prices will rise slowly.
The correct market hype depends on Bitcoin so altcoins are fastly growing in this moment but totally abnormal in market because Bitcoin is moving faster than altcoin so many investors are confused in this scenario. I hope market is positive in Bitcoin so others are growing in soon but still some peoples are buying altcoin so both are good growing platform.
