I have received a lot of valuable airdrops in the past, and now I see a lot of new coins, or the new airdrops have no important value. There are also many airdrops some time ago. Some scammers remind everyone to be careful about airdrops. Airdrops are rarely trusted now.
Yes, but you can still earn through Airdrops on the Binance exchange if you know how, because on the Binance exchange there are many things that their users can do, be it to trade as they wish, or to airdrop for those who are lucky.
