even the banks ask as part of due diligance.
Because we don't care, lol. As long as I can get my money back and get some profit, it's fine by me.
Unless it's a trust loan, I refuse to do those personally. Also, you don't have to tell the bank why you need the money, as long as your credit score is good, you can just say you need it for personal reasons, or you can make up an excuse.
OP, I don't think anyone will lend a lot to you with that collateral. Also, how much of those coins do you have?
I don't think it would be a good idea to 100% fulfill his loan, with that kind of collateral, you might not get back ALL the bitcoins by selling them, you'll crash the markets
