Think about it, if you could borrow $50,000 and put in into GLBSE, why doesn't the asset creator just borrow the same way as you?
Mostly because banks are only lending to people who do not need to borrow. For example, I have multiple credit cards with $20,000+ limits which I have not even charged anything on for months.
But I agree about the exchange rate risk and investment risk. Zero down Bitcoin investing is not the wisest move. About the most I have done with amping my Bitcoin related investment returns is 20% LTV.
Have done the CC thing a few times. Once they even gave me miles/points for writing the checks they sent in the mail.
