For me, in each crusade I have assign atleast 100 usd in each of the ico. It is smarter to spread your speculation not simply in a solitary crusade. In any case, you should anchor that the crusade you are joining to is a decent ico, and is a genuine. Numerous ico starting at now is a scammy write ico, so better know about that.
That would be a better value especially if you are just a first timer, I myself was just investing which I can afford too, but also I am investigating too whether that ICO is worth to invest or not. I should know them first before trusting them.
