There are a lot of new ICO, if you really want to invest in ICO, you should check the team and the white paper behind the project, if you think the project is legal, continue, but always invest in the money you can afford.
Do you think it's enough to check only team and while paper? I think it's very important to know that project has a prototype (MVP) that is working and possible to test it. Welltrado has it and it gives me additional trust in this project.
I think we need to check their community also because the community will decide that project will be succeed in the early or not.
