I've used them a few times. not only did they teach me how to do it correctly with the manual for n00bs http://coinmixibh45abn7.onion/en/bitcoin-mixing-service/how-to-use-bitcoin-anonymously/ -> first time I had an issue today and their support got back to me within hours and resolved the problem real quick. gentlemen
So what did they teach you? How to copy and paste an address and click send?
