I stopped doing Telegram-based airdrops, it's a total waste of time, three to four months of work, and getting dust will get you irritated.
The best airdrops now are those coming from testnets, and there are so many of these airdrops now, we still have to be very careful, where people are investing their time and money, expect scammers to be part of that.

I noticed there are many DePin airdrops after the success of Grass tried to work on some of them, but my browsers are affected by these extensions, so it's better to only choose what you believe is worth putting in your computer, of course, after your diligent research.
