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?
It can't be like that because the fair with the ICO is Fiat.
Ethereum and Bitcoin are only ICO coin exchangers, if the price of Bitcoin and Etheruem goes down then FIAT also goes down for the price of the ICO token.
