Please change your first post and thread title to something reasonable.
Maybe something like this?
Subject: I can boost or lose your BTC
Message: Despite having only negative trust feedback, I want to borrow your coins so that I can gamble with them. If I lose, I might be able to pay you back by borrowing from my friend, if he has any money, but otherwise you're SOL. Oh, and if I profit, I'll keep some of the profit for myself. I probably shouldn't lose your coins, although I recently turned 2 BTC into 0 BTC so who knows. Shit happens, right?
Currently your subject and message are pretty scammy. You can't boost my BTC, you don't have a system for winning, and you can't turn $5 into $7 with higher than 5/7 probability.
