I think providing a bitcointalk account as a collateral is not valid now. It's because Tomatocage will give that account (the collateral) a negative trust rating IF ever you defaulted on a loan
I know that well enough but I don't plan on defaulting on my loan. I had worked for this account to reach this rank and I am not wasting it with a single loan which I can get more from all the works I can do.
