ICO's have very positive future. If not regulated it could bring both clash and cash. Some ICO's has very short lifespan, in this point of view they should be regulated to avoid lose of investor's money, but when they began to be trustworthy they should be free floated, unregulated and free from govt. hand.
As Bitcoin became successful as free float crypto currency, all the ICO's should have their chances at some sort of point.
