I’m thinking about getting back into crypto mining in 2025, but the landscape has changed so much. Most of my old rigs from 2021 are outdated, and energy prices jumped in my region. Does anyone here actually run a profitable setup today? I’m curious how people balance hardware, maintenance, payouts, and the whole monitoring routine. And are cloud-based or hybrid options really worth considering?

Has anyone here recently upgraded their workshop with new ECU/TCU programming tools? I’m working with a mixed fleet — passenger cars, light trucks, and a few agricultural machines — so I need something versatile. Ideally, a device that handles reading/writing in different connection modes and doesn’t require constant paid add-ons. I’m trying to avoid suppliers that send outdated hardware. Any recommendations?
