most of the airdrops are scams, most of them are only looking for followers on social media ... but many are also good, it is very difficult to judge a good airdrop ,, I personally always participate every time there is an airdrop, if paying is good if it doesn't mean a scam ... that's all my step in following the airdrop
So what is your experience in earning via airdrops? I used to participate in every available also, was subscribed to lots of telegram channels and daily checked airdrop related webpages. Few years ago it was easy to find airdrops (scam and legit). But right now, I barely find any and get email notifications. I cant even remember last time I receive an airdrop token in my wallet, not speaking it has any value.
I think the telegram channels you are subscribed, they just want users to follow their channel more and then they make a profit by selling this channel or they just want to earn commission from registration to gain more profit from an airdrop program, unsubscribe and search for more quality systems is my advice to you. You don't even need to subscribe to telegram channels, you just need to look at coinmarketcap and binance, they have airdrops about new tokens, most of you will be paid a token to your wallet with a relatively good value after it is listed
