The crash of the market only affects ICO in the matter that some developers may choose to delay the lauch because of the big dip in wich BTC and ETH are in.
But from the investor point of view the financial effort is smaller like now because the parity of the ico price is the same: 1 eth - 12321 .....coin.
Now it is a bit tricky because i think that all good ICO should put a pause on the crowdfundig and that leaves you with nothing to choose from in this moment.
Be very carrefull because scammers dont care about any dip. They whant your btc no matter what is it`s price.
