Best way to earn passive income with crypto?

I see the crypto market as easy money. I'll prove it's a casino you can beat. I enjoy taking risks and exploring various degenerate ideas in crypto.

I would say two things:
- If you have no money to invest, try to participate in airdrop programs. 
- If you do have money, buy BTC/ETH and borrow safely against it(max 1/3), then use that money to get an extra return using DeFi. 
Then either buy more BTC/ETH, pay off your loan or add to your DeFi position. Or a combination of the 3.
