I think ICO is a good investment when the team behind them already has a big name, and their coin is useful for people's lives. Moreover, if the coin has its own blockchain technology, it is an advantage over other coins.
I believe so too. Since every coin out there having no good people behind it is as good as a scam even when it has a great ideology and solves problems. That is because investors are already very skeptical in the prpjects that they invest in since a lot of investors had been scammed many times by countless shitcoins out there. That is why, the team behind every ico is very important. Because even if an ico doesn't have that much when it comes to ideology, if it has trust from investors because of the team behind that project, it will surely become a profitable ico.
