Although there are many good ideas out there, aren't you safer to invest in an ICO which already has a functioning and proven product? ROI is much more likely in this scenario
I think so too, if they have a good product that has been used by many people, for what else we invest in ico which is not necessarily certainty, is it successful or not?
That's right. You really don't know these people you are giving your money to. It's a very blind investment but a proven product that is growing provides an enormous amount of confidence in comparison
