Some ICOs are legit some are scams. Most of them are legit. You need to study an ICO before investing meaning whitepaper, team, do they have a product, etc.
Since trading those days are very poor and volatile i turned my attention to new exchanges and ICO profit.
I've checked new exchange like bitpaction.com
They add new coins daily and they have many events during adding.
Take a look here:
