Just as Vod said, you are asking for 0.1 BTC for free here.

This isn't something that lenders will take a risk with. Also, since you already have 0.9 BTC why not just accumulate that 0.1 BTC? i'm sure that it can't be that hard, right? Unless you are offering up some altcoin, ofc.

Either offer valid collateral worth more than 120% of loan value, or expect to be denied. no one's giving away free money here.
