This discussion in Deutsch (German) is for beginners who are not ready to waste money. Good replies should explain what to learn first about power, heat, wallets, profitability, firmware, and realistic expectations.
Thanks for posting this. I was trying to figure out the same thing today.
For anyone still troubleshooting this, the most useful sequence I found was: confirm the wallet and worker format first, then verify the stratum target, then check miner logs, then look at temperature and uptime, and only after that start changing firmware or network settings. Doing it in a clean order saved me a lot of time because I stopped guessing and started isolating the real problem.
I ran into this after changing pool settings and thought the machine was the problem. In my case the miner was fine, but the network path was unstable and the shares started coming through only after I fixed DNS and restarted cleanly.
What helped me most was writing down the exact symptoms before changing anything. Once I compared the dashboard, local logs, and power behavior together, the real cause became much easier to spot.
I like this topic because it gets closer to how mining actually works in the real world. A lot of people read generic advice and assume the answer is always hardware or always pool-side, but in practice it can be wallet format, DNS, latency, stale behavior, unstable power, or simple operator error. The more details people share, the more useful this thread becomes for future readers.
It helps a lot when people include what symptoms they saw, what they tested, and what actually changed the result.
This is a strong SEO-style topic because it matches the real questions miners keep asking again and again.
This is exactly the kind of question many new miners search for before they commit money or hardware.
I think the most helpful answers here are the ones that explain what to check first, not just the final fix.
A practical comparison with real setup details would make this thread much more useful for future readers.
