Airdrops? Yes, it is one way that one can earn from crypto, but this time around, it is so difficult to know a legit airdrop that can be profitable because of too many scams in the crypto space. If you are looking at earning good altcoins through airdrops, you may luckily see them, but they are rare.I know I have made some profits from airdrops in the past, but things have changed drastically; it is not as before again. 

I have participated in crypto staking as well, but no good profit was realized while I still ended up putting my asset at risk. 

I am earning from crypto now through trading and also investing and holding for a long time.
