Solo Miners: An Unrealistic Business Venture Amid Low Success Probabilities

The author has dismissed solo miners as a scam, citing the impossibility of verifying their operation and their extremely low probability of successfully mining a block. While building a miner based on the ESP32-C3 board is feasible, the chances of mining a block are astronomically small, approximately 1 in 80 trillion, which is practically negligible compared to GPUs like the RTX 4090, with a chance of about 1 in 7 million. The concept of attaching a monitor to an expansion board, creating a case, and selling it as a solo miner is considered a clever business idea. The author mentions that creating mining code and a display output takes about an hour, a task trivial for neural networks, implying that such an enterprise would be more for novelty than practicality.
