And do they have a future in general?
I think regulation can be good...right now just seems like there are so many (potential) scams.
yeah i invested in an ICO twice , and it was successfull , if you wanted too to invest in an ICO you must know first what is the worth of their tokens in the future . Read their whitepaper , and their roadmap, and if it is interest you a lot , you can invest as much as you want . But there are many ICO's that are good at start but in the end its a scam , so be carefull to chose the ICO you want to invest.
