That's a very simple exchange. It will work.
It is just a simple USDT > BTC swap.
Just ask users to verify how much BTC you will receive, as there are fees (mining and swap fees), not a free service.
CCE.cash is perhaps a unique exchange that has a specific feature where it is possible to receive several different currencies within one swap order. Maybe it's a way to send a specific amount in one of the currencies
