Monero Dollar in and TUSD or DAI out
Why do you compare it with other mixers?
and NO...fee is not low.
I can just do one simple thing with much lower fee. Buy Monero and any other stable coin on exchange, when I want to buy/sell.
10-20 times less fee
Other than that XMRD is premined, and centralized.
