From an investors perspective, if someone wants to do something and they think it shall create lots of money, I kind of want to give them money in return for a guaranteed return of whatever they earn. We need some form of economic obligation to return this return. The current mechanism is debt, but this doesn't really work in both parties' interests due to the punitive effects of debt
Imagine I could deposit £100 into o2oo.io, then invest in a project, with the goal being that all spending of that investment must be through o2oo.io, and all payments and profits are also through o2oo.io and automatically reduced to pay the guaranteed return.
This derisks the investor and still guarantees a return for the worker.
The problem is trustworthiness. Do we trust workers to pay the return of investors? How do I know I shall get 3% of my £100 back? Or my £100 back when I need to?
