First of all as of this post 6000 dollars is worth 497.5 BTC.
You have okay history, but nothing as big as this.
If you ask me, you just plucked a sum out of the air hoping you would get lent it. Nobody wants be pay interest on an extra 102.5 BTC they won't even use.

Please nobody lend to him. If he likes he can provide me or another trusted party with id and other info, which they will release if you scam. But even then, you will not get your bits back.
