Type of Collateral: No (pero pwede nadin itong account ko)
I guess most lenders would not accept your account as collateral as the trend has already change now, if DT would know that you defaulted loan and the owner of the account change hands, they would tag it and that will make the account loss it's chance to join a signature campaign.
If you don't have some approval, try to reduce you loan request, you also have to understand that this is a non secured loan, and if in case a low rank like you would not pay, that would be a loss to the lender.
