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
Maybe youre right, but know what product it is cause some of them might not get the interests of people and so it might not really work as you think and youre most going to make any profit from it. If you look at the product and see it is something that no one would be interested in, then leave it and continue with something that you know about. Maybe you should continue with the white paper, if thats what can get you the profit you need at last.
