Red Fox Crypto Bitfortun BS-1 Video: https://youtu.be/6R1NaRx7eu0?si=fV__AZ1fo5WMb21c
Bitfortun BS1 fake hashrate exposed: the BM1373 lottery miner shows 5.5 TH/s on the screen and dashboard, but ...the real hash rate is about 5.1 TH/s. The firmware adds +400 GH/s in code.
Huge credit to JD at Harlo Labs for finding the +400 GH/s offset in Bitfortun’s GitHub/firmware, and to Red Fox Crypto for catching the API reporting ~5,100 GH/s. I ran the BS1 on my local Public Pool (Umbrel) and the extra 400 GH/s never shows up at the pool.
In this video I show:
• Stock dashboard vs API vs pool hashrate
• The boot screen starting at 400 GH/s before the chip even ramps
• Why pool numbers fluctuate and why 3 hours is not enough to “see” 400 GH/s
• Comparison with my Bitfortun Octa / Octaxe on real open-source firmware
• What Helium Deploy said about compensation for false advertising
• Why custom Harlo Labs firmware (like they did for the Hammer P2) is the fix
This is not stolen hashrate — the chip is hashing. The display and dashboard are inflating the number. On a small lottery miner, 400 GH/s is a real % of the spec, not noise like a 3–5% swing on a big-boy Bitmain box.
If you own a Bitfortun BS1:
1. Check API / pool average, not just the screen
2. Watch for Helium Deploy’s compensation / listing update (they’ve already moved the product page toward 5.1 TH/s)
3. Wait for Harlo Labs firmware — flashing the ESP32 should be straightforward
I am not a firmware developer. I missed this on the first review because I treat small-miner variance like large ASIC variance. That was a mistake on this class of device. Every GH/s matters when people are buying “5.5 TH/s” lottery tickets.
Subscribe for the follow-up when Harlo Labs firmware drops and I flash this unit.
