Diversifying is always the best way. You should split your money and make a few of both, ICOs need supporters of course otherwise they never turn into value tokens, but also you need to do your due diligence about the product they are trying to fund. Also if you want your money to short-term investment ICOs not usually the way unless they have exchanges set to be listed or sometimes they already have some tokens in the market or the Pré ICO already successful or something of the sort. For some coins, you better of buying them when the hit exchange, so diversify is the best way. I might give a few examples of what I am saying here.
