Maybe a year two -one project if you get behind an airdrop project you can earn like your friend. But I think you should pay attention to your investment because if you research and start investing from top coins then you will get good amount of money from here when bull season starts.
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.
well, if investing is included, then trading is also included, and that makes these two things the best way currently to earn crypto, even increase our assets. It's just that, I think people will look for free ways to earn crypto, and that might be in airdrops, bounties or selling skills. Even though it is currently quite difficult to get crypto from this method, this method can still be used.
