TUSD or DAI in and Monero Dollar out
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.
Goal:
the mixer goal is it to make it more private
the monero dollar goal is it to make it as private as possible with the monero technology and modified atomic swap contracts.
people use stablecoins to get not volatile coins. if you want to sell or buy products, it is much better for you and the buyer to use stablecoins because on the next day you own still the same value.
the most people buy monero because of the privacy and if you buy any other stablecoin on the market your privacy will no longer be available if you use it to buy and sell or pay anything.
