Airdrop is not something new in the crypto industry. The method of distribution has changed. It was very easy to get an airdrop before 2021 but most of them were scam projects. Right now airdrop criteria have become harder and the user needs to spend their own money to get an airdrop. So we are getting more legit projects than before but this time the criteria are getting harder. Also every project is innovating some new methods for the airdrop so i guess it will be harder in the coming days.
I still think that there are classic airdrops left but their numbers were maybe smaller now compared to that new airdrops you are telling. I do not know that if they will get extinct soon and fully replaced by a new airdrop but I feel bad about it even though I'm not into airdrops anymore. I guess it's because I had a good memory or moment on them in the past.
Once airdrop has fully transformed into a new one, that should be the time for us to see a lot of scam projects and it's more painful this time, knowing that airdrops are not free anymore. The project may be innovative too, for them to have an innovative method for airdrop but this can also act as a protection for those who wants to abuse it.
