⚠️ What to Know — “Mining Lottery” Nature
Because this device is a “lottery miner” — not a full ASIC rig — the probability of mining a real Bitcoin block is extremely low. Think of it as an experiment or hobby rather than a guaranteed profit-maker. Use it mainly to explore mining mechanics, test firmware, or learn.
NOTE: All devices are tested before shipping. Recommended for tech enthusiasts and miners who understand the solo mining process.
