And now there is no place where i can change the UNB to something else?

Hi. I`m a newbie in mining. I was configured ma ASIC to the UNB pool a few days ago. All these days it was 'currently undergoing some maintenance". After i get some coins and created an account on Bittrex i`ve discovered that i can`t generate a UNB-address to deposit my coins. Moreover today they posted a message about delisting of this coin. And all this time i see the new buy/sell orders. What is it? Is it usual for Unbreakable?

Джентльмены, подскажите, пожалуйста. На офф сайте DigiByte вижу 3 адреса пула для SHA-256, с разными сложностями (8К, 16К и 32К). Как из них выбирать? Чем руководствоваться?
Спасибо.
