About Bittrex, well, after they asked for $5000 in $ valute, i just stopped to talk with them. I understand paying for listing and we are paying, yes, but bribing someone to do this, can not happend.
I know it's not the first on the priority list at the moment but checking out the example of Tor market http://mwy3ogagzse5cubq.onion/ and i hope you will make it work without javascript for maximum security.
