They should have been verified long long time ago with those kind of numbers. I have to admit that I didn't know they weren't verified, but I have worked with some projects before and they got verified in 6 months thanks to being non-gambling website I suppose.
The only reason I could think of why bitcasino.io wasn't verified must be regarding both crypto and gambling together, shouldn't be that difficult if you ask me. Kudos to them for finally getting it, you guys deserved it long time ago and you guys have been doing a great job, the support is great, games are great, never had any shady deals, always on top of the game and that is why we love you.
The number of followers didn't determine if you will get verified or not as they look for other things also and you need to have presence over the community and active for the time.But still Bitcasino.io is now verified which is good for us.
Oh yes, it seems Twitter, which has now changed owners to Elon, will change some policies such as if we retweet from a verified account, we will be charged. I heard about it from the chat in the group chat but I haven't looked for any more news.
