Okay, so my fix is better to wait for the announcement, it's much better before making a deposit, thank you for the advice.
Blackjack hasn't been active in the last few days either so I thought he'd definitely let him in here.
As I can see on blackjack.fun that today they have made an update few minutes ago. And the update brings some change in around Tether. Tether is now show as USDT and the address is now with 0x prefix. It already confirmed by admin in chatbox. Now player can use USDT for making deposit and withdraw without any confusion. Good Luck guys. Enjoy you blackjack strategies.
Thank you sujonali1819 for this comment and thank you all who notice this!
Thank you sujonali & Blackjack for telling me, to be honest I was late visiting this thread a while after the update was complete.
And after I checked it was fixed now, there were no more problems, maybe when I made a deposit to try it from USDT.
~~I am asking from all of you, what would be the best time to take part of it in UTC time? Any suggestions can help.
Because there are many different regions I think it is uncertain, but in my person it is certainly 12:00 UTC time because it is the curfew rest time for Indonesia.
I think it's much better to have 2 times a day in a Freeroll tournament but I'm sure lots of people will spend in this tournament.
