The best way is joining in a bounty campaign, if you want make money without trading and mining. No risk and simple way to make money in crypto.
it is easiest to join several existing airdrop campaigns. although not all will be money, but if I am willing to do a lot of airdrop projects I think there is a possibility of getting money. Bounty is also good, but like Airdrop, there is also the risk of not getting money.
