2) I do not consider the possibility I am wrong about this matter. There is no legit Investment vehicle that returns 3000%+ per year. Please do not trust me on this matter - ask anyone with a degree in economics. Ask any accountant you know. Ask any banker, any stock broker, any CBOE bond trader, google it - seek your own information about this very important point and understand then why I can be so certain.
Just by the way, and it has been said already early on in this thread, if somebody indeed establishes the unlikely ultra-high-yield business, he does not borrow money and distribute the gains. He keeps it for himself.
If pirateat40 had a business that yields 3,300% a year, he could invest one bitcoin and then earn 10 million bitcoins in 4.5 years. Of course he could also invest BTC 10,000 and earn 10 million bitcoins in just under two years. Why would he borrow money from others and give them the gain? Because he's such a good, altruistic person, of course.
Never mind that 10 million bitcoins do not even exist yet.
