do you think Purse.io could benefit from using flexUSD?

For those that have used purse.io to buy or earn, what would you think if you could have a balance in flexUSD that doesn't swing in price while waiting for an order to be accepted?
One way could be the buyer swaps BCH to flexUSD and sends it to their Purse.io wallet and when an order is accepted, a bot/script could exchange the flexUSD for BCH at the rate at time of acceptance (as that's when it's normally locked in) for the earner. This would remove any issue of balance swings on the buyer's side while an order is pending acceptance

or perhaps the earner could have an option to accept flexUSD instead of converting to BCH at order acceptance
