For me it would be Airdrop and bounties on cryptocurrency. I did trading in the past and almost lost all the money I get from airdrops. In airdrops/bounties you don't need to learn so many things like technical/fundamental analysis to make a profit you just need to invest time and look for sources where you can get legit airdrops/bounties. You also don't need to invest, you just need to work things out here. Just search on google how to make money on cryptocurrency bounty campaigns. I already abandon airdrops as more and more scam airdrops are popping so I am just now focusing on bounties and thankfully my first bounty was a jackpot sold like $600+ and left some worth $1k+ to make it grow more.
In your first sentence, you suggested airdrops but you concluded that it's no longer profitable and you have already the use of it so it's kind of misleading.
Airdrops or bounty campaigns is a way to earn crypto, but it's not regular neither secure. There are some crypto jobs out there that are available. You can check out some sites that offer projects or jobs that will pay you in crypto. Web creation/design, graphic design or even just data entry jobs. Of course, most of these jobs are just project based or contractual but I find these more secure.
