Well I was told by richie in bittrex slack you have to pay 3btc to get listed.
That's not the issue - we've submitted our documentation, clearly stated we have no complaints with paying the listing fee and are waiting on their response.
On our side we've done what we can and are waiting on their decision.
It's probably just a matter of time then, it seems to take a bit longer with them having to run everything by their lawyers nowadays.
