Coming back to the old days, hunting airdrops was basically to follow few insiders, read the news and use all protocols that had no token. Currently there are thousands of influencers announcing airdrops even from projects that did not comment, projects announcing airdrops before have a product and a lot of noise.
I feel is is getting harder and harder to get good airdrops, when some arrive the tokens are diluted by a huge amount of airdrop hunters not to mention projects that "gamefi" airdrops with tasks and points, terrible.
Maybe it is a wave that passed, not sure about the future of airdrop hunting.
Airdrop wave is not passed and still there are some good project which can give very good airdrop in the future and you should not miss them.. If you research then you will knows that in one year many airdrop hunters get a very good amount just by following simple task.. Arkham gives people a very worthy airdrop and task was to just register(2 minutes work).. Arbitrum gives also worthy airdrop and task was to just perform some transaction.
There are still some projects like Zksync, Linea, Venom, Zoro, Scroll which has potential to give airdrop in the future.. You can test and I hope you will get worthy airdrop.
