I think the time for those telegram hype has come and gone. All those onces that are still active are there, with the glory of those that were successful, like the notcoin, dogs, and $Cat, which are the ones I can recall. Telegram game airdrops like hamster, which was among the most hyped, were just fucked up, and many of them used their players to gain traffic all over their social media and streaming platforms like YouTube, which I believe that's what all of them are doing currently.
 
I won't discourage you from giving it a try, but just don't put your hope expecting any big reward from anyone that's being recommended to you here.
