Yes, STO's can be a new attraction for new money to come into the crypto market.
I see many people are tired with utility tokens (especially token without good mechanism) where they don't get anything from holding it and just hope the price will increase.
I believe as well STO are what this market need to get back on it's feet, not on the short term i reckon, but perhaps within 2019
I wonder how bounties will work for STO's. They won't do any or they will pay with eth/btc or will they continue like regular, giving out their token.
