Since the end of 2017 no one can predict if ICO tokens would bring you any profits. Pretty often obviously shitty projects are getting a good price simply because they were heavily advertised by some well-known shitters like John McAfee while some decent projects are hardly hitting a soft cap, cant get a decent exchange listing and then remain with zero volume.
Right now early investment is a bad idea simply because it is impossible to predict the future of the project. Even in general ICO investing is not a good move.
