- they don't give us the same oportunity ...
What does this mean? We're not getting any advantage, we are all investing personal income. You mean BTS trust should pay you also?
Well, employment payments deals and negotiations are non-public, so we have no way of knowing there isn't a contractual obligation to devote some % of pay above the real salary to cycling funds back through. If you want people to be vested in your ecosystem in a way where they can't leave, Angelshares do that well.
I'm not suggesting this is being done, but that it's a plausible explanation for the rather heavy re-investment. That person is mostly competing against themselves, which is not an entirely rational strategy.
