Hello, here is my response and will be making a clear and better post.

1. I have no real way in guaranteeing your money, but you can see @bellyrub's transactions daily its make over 200 SBD.
2. I Think I will doing a post about that might be more attractive - delegated-SP is lower risk to the investor because they can claw it back at any time (with a seven day cooldown)
3. At the moment it will be set manually but if and when it gets more traction I would get that automated just like @bellyrubs process.
4. It would be easier and faster to pay in SBD since bellyrub takes sbd no need for market sales.
