first of all, thank you all for the feedback!
well its not like i did something very illegal. I just want to go sure. Anonymity is important for me.
The concept I suggested has one advantage: anonymity is assured by monero which is open source. Those mixer services are mostly not open-source and have more likely a vulnerability than monero.
and yes both services (morpthoken and xmr.to) have no KYC, no registration
Yes the fee's are def a con. I already tried it, its smth about 5% fee in total.
@BitMaxz, thats a very interesting method. Heard that first time that a "mixing" service doesnt actually mix but use new coins. I will have a look. The good thing is, you can verify that the coins are new.
Edit: cant see on the chipmixer website, that they mention to use new coins :S ?
