So I guess the devs are not going to communicate with Crex24 to clear up matters so trading/deposits and withdraws can resume there? weeks now. Crex24 is waiting to hear from you. 
Also note https://cratex.io is a BTCZ friendly exchange that uses BTCz as its base currency (similar to Binance's BNB).
