If you don't feel safe investing on Ico just wait for the token in the exchanges. Lately it's safer for sure.
The problem with that is, if you miss the ICO, you miss the opportunity to earn significantly bigger profits. However it all boils down to your risk appetite.
I would also like to say that you should continue investment in crypto currencies, In fact there are so many potentially good coins, which are still trading low but still they have good potential and in near future we can see such coins to increase their price too much.
