Ethereum based stablecoins are hardly the best way to do this. From a user standpoint you have to 1) buy your stablecoin on some exchange 2) transfer it to your own wallet 3) pay a hefty fee to transfer it to the recipient (>$20 when the network is busy) 4) Recipient pays another hefty fee to transfer it to an exchange so they can offramp.

If I'm sending a remittance or similar paying $$$$ in fees is absolutely not desirable. And with current gas prices the cost of sending anything less than 50k is pretty comparable with just doing a wire transfer.
