Are all of these recent icos good for the economy of crypto? I have seen a couple of brilliant one's (ethlend). But some, are garbage.
Many ICO is scams or with a project having no scope. Investing in such ICO is a sheer waste of time and money. So investing an ICO having a strong team with a clear vision and a promising product can only give you appropriate return on your investment. So it is very important to study extensively about the project and team before investing in an ICO.
