Important as ever: DYOR as not all ICO's have a genuine solution to a genuine problem. Some may seem like a fantastic solution, but often it is marketing combined with a strong team, and not so much a great working product.
you are right, some ico have a very strong team maybe because they pay people with not small money, and this is not a great working product, after they won hardcap and listed in exchange, many investors were disappointed because the project never developed and has a value that is very far from ico prices
