What is maximum amount we can mix with your service? Also how much you have in reserve, you should post a signed message with address holding enough bitcoin to process maximum amount that can be mixed with your site.
You can send that signed message to few of the trusted member of the community to verify privately if you don't like to post it publicly. You are new so you need to earn some trust before you can get customers.
On this forum I have no acquaintances, accordingly there is no person to whom I could translate 11 BTC. I hope that customers will leave feedback here, as well as in other forums, and I can post links to the threads on my site so that new users are not afraid to trust us.
Our automated system is designed in such a way that if there is a shortage of funds for mixing bitcoins, we return the customer's funds to the address from which he sent. Commission for this is not taken. This can happen if you want to mix 11 BTCs twice a day. But we will soon fix this. At the moment, we have already found a partner who will help us to significantly increase the total reserve of bitcoins.
