I thought the airdrop isn't worth since 2018 but after reading your reply it seems still there is chance to make some money but it could be difficult to find actual airdrops from scrutinizing all the available airdrops. Well this is the only way if we don't want to risk our money with new coins and still interested in tasks to get decent chunk of them.
The current airdrop is different from a few years ago, which at that time was much easier, so many of the airdrops were scams. Currently, it is quite difficult because there are tasks that have to be done, but several members have said that the prizes they get are worth it, I am also quite behind on the current airdrop. In fact, it could be said that it hasn't produced anything yet, and it's not easy to get information about the ongoing airdrop, some websites that provide information like that are very limited and only open all the information to their paid members, so at the moment I'm only focusing on memecoin and that's only on Shiba Inu and dogecoin by becoming a long term holder.
Airdrop is still a good option, but you need to spend time and money, and you don't know when you will get something, and if you get it overall. The first thing you should do, it's education, and find a good community of the likeminded people!
