It does not matter what idea the project carries. Let it be a technological sphere or any other, it is important who is behind this project. Study the team and project advisers
I disagree, it's important to know what the project is all about because it determines whether people will use it or not after its ICO stage. On the other hand, ICO investing is high risk depending on a lot of factors. Factors such as the project itself, its team, and supporters.
Speaking of legit projects, I've been following Menlo one since its token sale announcement. It's a decentralized ICO marketplace where its CEO mentioned about having solved the various issues most investors face in ICOs. Anyone else planning to participate in their ICO?
