Ask HN: Passive income ideas for blockchain developers?

I've been working full-time in the blockchain space for the past few years, with a focus on Bitcoin and Ethereum.

Commonly used stack: React, Node.js, Redis, MySql

Commonly used libraries: web3.js, ethers.js, bitcoinjs-lib

Do you have any recommendations for passive income opportunities in the space?

“Passive income” on here usually refers to overlooked opportunities to do low risk, low reward web apps. Since you want to do something in the blockchain space, and the only proven market for blockchain technologies at the moment is blockchain developers and speculators, you might want to do something for those demographics.
