What is this - concern trolling?
Bitcoin will go up - and it will go down. There are several reasons, check out google for some of the things it can do. This is the year of lightning network - and a ton of alt coins and ICO's / SEC etc.
Strap in.
If indeed ICOs is one of the reasons why bitcoin declined in value then it would be better to invest in altcoins or in ICOs but ICOs are not 100% sure profit too. Too many ICOs it is even hard to identify the real ones from the fake ones.
