The requirements on the escrow are quite high. They would need have a verified Qryptos account (only place that Zebi has liquidity on) and be able to ensure the lender doesn't lose money (not only by selling at the right time if the price drops but also guaranteeing that the lender gets their funds, effectively vouching* for Qryptos).
I don't know if any escrow would be willing to do that, but if so, I'd be interested.
*Whether or not their withdrawal gets processed on Qryptos the lender will receive his funds.
I mean the funds could always technically be liquidated and withdrawn at a later time without a full verification initially, should that situation arise no? Good point though
