I have saw another crypto mixing services who show their proof of bitcoin to another users bitcointalk, do you can do same? And it will make your services more trusted by costumers.
What proof do you mean? We generate Letter of Guarantee signed by our account 1BitmixerEiyyp3eTLaCpgBbhYERs48qza for every mix. It is a digitally signed proof of our obligations. In case of cheating anyone may show this Letter to public. We have outstanding reputation since Jan 2014, currently we process over 80,000 btc monthly. I think no additional proofs needed.
