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.
This is what is happening in todays crypto market. It cannot be more accurate than this. Big budget companies can advertise and scam their way into even bigger budget.
Good ideas and low budget companies hardly get the chance to break through.
I read somewhere about a company that stimulates projects to achieve more and grow. Something along those lines but cant remember the name anymore.
Investment is only good if you understand the idea and execution. For that, you have to dedicate your time. Many investors wont do that. They want fast liquidity, fast money, fast execution.
