In the traditional fiat system, vesting, notes, bonds and rights issues are all financial instruments that allow debt to be used as an asset.
I'm not certain how I feel about the financial experts applying their shittery to Bitcoin. On the one hand, Bitcoin should be strong enough to cope with it, on the other, there is a real chance that Saylor and Trump and others could turn Bitcoin into a shitcoin.
I suspect these will be incredibly successful strategies that will work until they don't, just as mortgage backed securities were incredibly successful until 2007.
I hope that when they fail they won't take Bitcoin down with them. We shall see.
