This year, I'm going to find a legitimate way to make a sustainable income in web3/crypto. 

With a technology focused primarily around money and with trillions of dollars in the space, surely there's got to be a way to pull this off without resorting to gambling.

Good for you, and good luck. It's a lot harder to find a sustainable income than you'd think, given that (as you say) we're in a space with programmable money. 

In my 4 years in crypto, I've managed to do it about half of that time, but in hindsight I think lucky timing (i.e., bull market) played a big role.
