I don't think they are going to return ever again. Even if they does, I don't think anyone who are aware of what is happening for the last few weeks, will be interested to play with them. Betnomi destroyed their brand and only they can blame themselves for it.
Betcoin reputation becomes very bad here after multiple unresolved issues and many red flags activity in the forum. You can check this thread
https://bitcointalk.org/index.php?topic=1322261.msg13507632#msg13507632 as referenced on all of their bad deeds before they change management to the current one.
Betcoin bad reputation stays there from 2016 to 2020 (I'm not sure on when the date Betcoin starts new management). This proves that forum acknowledges those casino that is honestly wants to improve there service. Betcoin is now back from being reputable here in the forum with an active signature campaign since their new management.
