I forgot to include investing as a way to make money from crypto. But I agree with you that one of the best ways is to invest. But unlike airdrops which you can get for free or with a little capital, you need a little more capital if you want to invest. But I think investment is the easiest option to get money from crypto because you can choose a good project and you just put your money there.
I think crypto is currently running quite rapidly and we are always trying to achieve it even though it is in the spotlight in the financial and they invest or own this digital currency, by doing various methods such as airdrops, bounties, they continue to try to succeed but it is a challenge that It has to be finished by looking for a free way to get crypto, but I'm sure there are many people interested and many of them join this commodity such as Reddit, Telegram to find out and get the latest information about airdrops which are taking place at the moment.
