Bitcoin price hugely affects the price of almost any cryptocurrencies, and the only one underlying reason of it is almost all the cryptocurrencies are bought through the Bitcoin, that's why once the Bitcoin drops down, then all the market goes red. It can't be applied vice versa. Current situation on the market is really strange and horrible because you are uncertain of your trades and you can't raise money normally. idk, right now I'm HODLing only, because I know that in just 1 year I'll be able to sell those tokens that I bought on ICOs with high price. Actually I really advice you to put your attention on the project which is called Cryptics, these guys have developed an AI based Trading platfrm which is able to predict the prices of different cryptocurrency assets. THey gonna have the 2nd ICO round soon, I've invested there already.
