What is the need of always mining many of these Telegram airdrops when many are just big scams. Those that had lost huge amounts of money that should have been invested in real project, they are the ones that know what it means by trying to succumb to the interest of many of these telegram airdrops, asking for transactions so you can benefit from the airdrop. We ought to use our time for something benefiting not in airdrops that will take your time and later disappoint you when you are expecting something huge. There are good airdrops and many bad ones, so we need to keep looking for the good ones, maybe not on telegram.
You are right, most of them are scams, and even more of them are just failures, so there are not that many which ends up being good. I mean it takes literally 15 minutes to make one, so why wouldn't people try their hardest. Even people who have absolutely zero marketing fund, end up creating one in an hour with all the design and all, and hope that airdrop hunters would make it go big, which they don't because if there is no marketing budget then they would not hear about it.
Only the ones with some budget for marketing end up getting heard, and even those ones do not end up giving good amount of money to people neither. Which is why we should be avoiding this as much as we possibly could, we can't make it work.
