I found what I think is a great investment opportunity and I would like to put 20 dollars on it at the moment but I can't get any bitcoin for probably about a week.
Repayment should be no later than june 6th.
edit-
if i can not repay you buy june 6th i will give you what i invested in or i could send you a small piece of gold or something alike in the mail.
Since almost all lenders require 120% collateral, in hand, i presume you're going to send $24 worth of gold in the mail to whoever is giving you the loan, and you're going to cover shipping costs both ways? This is going to end up costing you a lot more than the extra intrest...
