Your YouTube channel isn't collateral.

You can reposes that easily with either:
1. Your old password
2. Your phone number
3. Your recovery email

So it's a fairly useless form of collateral as it's so easy for you to get it back.

Do you really have nothing better to offer (I mean 0.015BTC is a lot of money to lend to an anonymous stranger) - especially given your trust.

Are you hoping to get both of your requests filled also - simultaneously, and why do you want an extra 0.001BTC from this one?
