Hi, requesting a loan for 4 btc.
It is to be used for a swift serious business investment with a quick payback within 5-7 days.
As far as collateral goes the interest for this loan will be a 60% when paid back, no bank would give that interest no, so its a good opportunity up for grabs. Contact me on my ICQ for further discussion on collateral if you are interested in making money fast.
