Review: I received the fund. And try to mix it free. At first I confused by seeing minimum 0.005 BTC have to send. That also noticed by other people here. Unfortunately I send 0.0012 btc with 50 sat/byte fee. It’s seems 135 confirmation from my wallet tnx history. But I did not receive any BTC to my output address. It’s already 20+ hours gone. Even I did not receive the fund back to my sending wallet. So what will if anybody send any big or little amount than 0.001 btc unfortunately for free mix?

It has been explained above post #22, you transaction detected as dust transaction by the system since you haven't sent enough fund for anonymous mixing. Because more than 0.001 BTC will consider as a real mixing (not for the test). That's why OP stated that you have to send exactly 0.001 BTC to the free mixer.
