I repair and mine on ASIC and FPGA Miners (Crypto scum. I would only recommend the former), as well as do contracted electronic hardware and generator (diesel and propane) repair and installation for local businesses. A good hustle to say the least, allows me to live alone and play this shit all day most days at 22 (depressing ik). I also volunteer in my State's Flood Rescue Service (NSWSES Team Leader, for any fellow Aussies here).
Idk if i do mine but I do outside of perp school, focus on geopolitical issues around the world, watch good tv, photography however I'm at the age where I can't do much hobbies rn I enjoyed the gym planning to go back
