is it a good idea to invest in ICO's and what do you think is a good deciding factor to pick what ICO's to invest in?
Surely, the team behind the project matters most than any other factor. If you have a low profile or weak team managing an ICO project, you don't expect much success from such ICO.
if the project has a weak team, then just the project will not be successful. Investors now become very smart and they are making a good research of the project before they carrying their money. so I think that projects with a weak team simply cannot raise enough money
