Many ICOs have their token sold at a fixed price vs. the ETH. For example: 1 ETH = 1000 Tokens.
So does it really matter if the prices of ETH/BTC is dropping?
If anything, then buying now you get more Tokens for the $, right?
currently investment in ico is not so good, but there is always an option especially on ico which is really good. yes, you still have to research it and analyze it before speculating, but if I may suggest, it's better to invest in altcoin in the current situation.
