Currently you will not find any good project in Telegram. Currently all projects are scams. Currently, participating in Telegram projects can not expect more than 1-2 dollars. You are right, currently participating in this project is just a waste of time. Notcoin and dogs were the best, you won't find better projects like these two projects. I participated in several projects in the past, but just wasted time. So currently I stay away from the Telegram mining project.
Just imagine on that, one would have spent a lot of time farming for them, using his data and time wasted to just receive a penny as reward, this does not end there, because at the cause, you will also be required to make some deposits on Ton and by the time you make the calculations with what has been offered, you will discover it was nothing than a pure way of scam and time wasting, i think people are getting to know more better now than before.
Unfortunately many of the projects were like that, and people realized it too late and that resulted with bad returns for many people. I do hope that everyone gets a better result, and they get great airdrops and tap to earns, but so far we haven't seen much.
Even the ones with 100+ million members, ended up with just a few dollars as a reward, and not only that but the token price crashed after a week or two and that meant even lower rewards. So long story short, we can't really keep having hopes for tap to earns, unless they show otherwise, so far there were literally just one place that paid well, everything else, hundreds of others, failed to give any decent return. This is why people stopped putting effort into them.
