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?
When we talk about market conditions this time, i could say its 50/50 now, with the continuance of price dropping, i think and i believe its your own prerogative to invest, invest at your own risk as this time, we are facing a market crash or something like that. And if you think that the project has a future, then go for it.
