So essentially locking up the funds in a smart contract so a bot would use the money to make said money into more money? That can be done by individual users doing crowdfunds or a smart contract platform like rootstock is to bitcoin. I don't think it's nessesary to add trustless smart contracts to steemit, because that idea is lacking in research and development.
Just look at ethereum. It has only like 3 working DAPPs so far. There isn't a need for smart contracts currently.
