Your option 1, I want to do..i want to learn more about it. Then I aim to option 2 and because I don't have money to option 3.. so I want to rent out for others. I am thinking about it might take care that way of it's own costs and give me a little to live.

The problem is, I don't know how. Own hardware is a problem, I don't have a home. I am living minimalist and nomadic life. Ok,. basically I am a hobo. My sister said recently that I am a modern homeless and rewriting the word homeless....

Whatsoever, my Idea is to run a node, BTC, lightning, nostr and give something to the community. It should take care of it's own costs and give me a little money to make my life a bit better.

I just don't know yet how. I thought about doing it on a hosting somewhere, but that could get expensive and make me badly broke. So I am keeping my eyes open, maybe I find a solution.
