Hello,
I have a problem. 2 days ago i sent BCY to Poloniex echange, but i didnt receive them. I checked the transaction in block explorer and there i can see that the transactions was successfully. I wrote to the Poloniex support, but they havent answer me yet. What can i do more?
You cant do anything more then to wait for Poloniex support to answer your ticket. If you sent it to right address that Poloniex gave you for your BCY deposits all should be fine.
