Well, first of all you should learn how to choose a good ICO, also do research to find out good ICOs for yourself. ICOs can be very profitable if you choose the right one. There are a ton of ICOs out there, with every single one of them promising huge returns and useful perks for potential investors. But before you get carried away and start sending your hard earned money to every single project out there, remember that many, if not most of those projects will inevitably fail or will turn out to be a scam. So be careful and don't commit more money than you can afford to lose.
