Solo Bitcoin Miners (Bitaxe, Nerdaxe, NerdOCTAXE)

Solo miners in this category, including the Bitaxe NerdOCTAXE, Nerdaxe Gamma 601, Nerdaxe Ultra and Nerdminer Pro, run SHA-256 at hobbyist scale rather than industrial throughput. These are open-source-derived designs popular for learning how Bitcoin mining works and for the small chance of solo-finding a block, rather than for steady pool income.

Power draw across this group ranges from roughly 3.5W on the Nerdminer Pro up to around 18W on the Nerdaxe Gamma 601, low enough to run continuously off a phone charger or small power supply. Hashrate is correspondingly modest, measured in KH/s to TH/s rather than the hundreds of TH/s of rack ASICs.

Buyers typically point these at solo mining pools like CKPool or run them purely for the hashrate display and learning value; treat any block reward as a lottery-style bonus rather than a planned return on investment.
