Bitcoin dominance is mostly being felt on altcoin performance, this is not the first time this will be happening, being the leader in cryptocurrency, bitcoin has everything it takes to move the market and make it react towards the particular direction, and whenever bitcoin is falling, also create a serious implication on other coins to react in similar pattern and that is where we are seeing some of these performances with the altcoins this season.
There is nothing people can do about the dominance Bitcoin have over altcoins. I think majority of the altcoins we have in the market can not move on their own without being influenced by the price of Bitcoin. Once the price of Bitcoin starts falling, almost all altcoins will find it difficult to resist the influence from the price of Bitcoin and all we often see is sharp fall which can be serious and severe that the extend the price of Bitcoin has reached. I don't know if this is the way the crypto market is programmed but that has been the way price has been moving.
