Don't limit yourself to those, you can sell items or provide services and accept cryptocurrency as a payment honestly it is not easy to make money with cryptocurrency since you need to provide something in order to get something. Even in faucet or bounty campaigns, you need to provide your time and efforts to receive reward it's not actually free and even the airdrop there's a lot of task you need to do to receive an airdrop.

So for me it's not easy to make money with cryptocurrency but there's a lot of things you can do to earn with cryptocurrency.
