I spoke with bittrex CEO. If we want to be list at bittrex we must complete 3 conditions:
1. Make stable and working wallet for all users (without Runtime error)
2. Make big hype on twitter with tag @BittrexExchange
3. Create a request
C-cex:
We need 300 votes and we have 4,5 days... we need 0.3 btc

if all investors pay 0.01 btc we made this achievement in one day
We have also talked to Bittrex and they have told us that it is based on community demand but they will look into it.
