ICO investing is high risk-high reward depending on a lot of factors which involves the project itself, team, and supporters. Sadly, some ICO investors have either quit or are waiting for a better investment system to avoid losses from scams. Speaking of good projects, I've been eyeing one called MenloOne that's going to launch as a decentralized ICO listing marketplace where its CEO mentioned about having solved the various issues most investors fear in ICOs. Has anyone heard of this project and its team?
If the team have already had a good reputation, it is a good sign. But anyway you should do your own research. It is always risky to invest.
