telegram base i think is only starting. theres a new one, just saw today promoted by signature campaign. other than telegram base, seem nothing new.
Yes, I agree with you, the Telegram based casinos trend is the latest one and it's not over yet. I expect to see many mini apps of casinos on Telegram. Hope that this trend will stay for a long time.
As we know the mini app game has a lot of demand... so it is likely that the casino will integrate its operations into telegram like some other casinos, this trend has not ended and now many casinos are on telegram but I only know a few.
Some casinos that are about to launch their tokens, have already started moving to the telegram mini app and as we know FortuneJack has a bot there it is not impossible that not the old casino can also integrate into telegram like other casinos.
