Another new mixing service? Why not, free to test, here's my address: bc1q2aj8jasgscv0982dc7u4uvd7gjr2afdn6u8dfs. PM when done, in case you send and expect a test quickly. I don't always check my wallet, but if you don't mind waiting, within 48 hours for sure after confirmation.
Assuming bech32 addresses are fine to enter in the "receive mixed coins" to? Does the "delay" option affect time of tx or tx fee?
