https://info.btcz.rocks/Check "Exchanges" paragraph. There are at least 3-4 exchanges where you can vote for BTCz without registration. Don't be lazy. Vote up!
Also what do you think about Coinomi payment: 1.25 BTC + 0.25 BTC in BTCZ ? Maybe better to add some funds and pay for cryptopia listing?
Coinomi is a good popular purse and the price is moderate, and the listing of cryptopia 5 BTC is expensive. It is better to file more applications for Bittrex, we have a good community, it should work out.
