I don't have anything to offer as collateral that I know of. You guys can give suggestions if one is needed.
You can offer any altcoins if you have or anything solid digital good if you have to keep that in collateral (not gift cards)
And come up with any collateral if you have otherwise you will be treated as a Scammer
Potentialy gift cards could be used.
If you get a gift card like an Amazon Gift Card, the escrow service sould enter the code provided into their Amazon account. When you pay back the loan amount, they jut hae to click the cross next to the gift card to move the ownership back to the party that took out the loan.
You woul dneed an escrow that was skilled at this though.
