I saw similar projects in the past with some variations, of course. Now, the use of smart contracts, I assume, can be guaranteeing that an "investor" will be getting the profits he/she deserves out of the operation. I am not so sure if there can be a platform that can help you with that concern but am sure there must be out there. The use of smart contract is making the project more attractive but these days investors can be demanding more...they want to know if they are dealing with a genuine project and real people so they can avoid being victimized by another scam or rugpull.
