I will not give up on Ethereum yet. As you just said, STO's requires real investors with huge amount of money, I think their main problem will be the number of real investors that they would have. On the contrary, ICO's can be bought by anyone and I think its a much better risk than STO's with only few investors on it. The only problem with ICO's are the scams, if crypto can take care of it, Ethereum has a long way to go.
