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
This can be useful feature sometimes, and I think it can potentially save fees in some cases, and maybe it could be a bit better for privacy if you know what you are doing.
I like they are supporting monero, and I think they have biggest list of supported stablecoins I ever saw.
One thing I would suggest to CCE.Cash is adding .onion link website for better privacy.
