About the Bitaxe Naja Duo
The Bitaxe Naja Duo (model 1201) uses two of Bitmain's newer BM1373 chips. Sellers state about 4.4 TH/s at roughly 42 W at stock, about the power of a GT 801 for twice the hashrate. Listings that say 8 TH/s are quoting an overclock at about 92 W.
Best for: Bitaxe owners who want a big efficiency jump in a small, quiet board.
Check before you buy
- 8 TH/s is an overclock, not the stock figure.
- Some listings are pre-orders with multi-week shipping. Check the badge.
- Power supply: pick the North America option where offered.

Questions
What is the cheapest Bitaxe Naja Duo right now?

Is the Bitaxe Naja Duo in stock?
At the last check: Solo Satoshi: in stock; Bitcoin Merch: pre-order. Stock changes fast, so confirm on the shop's page.
How much electricity does the Bitaxe Naja Duo use?
Sellers state about 42 W, roughly 368 kWh a year if it runs 24/7. At $0.10, $0.15 and $0.25 per kWh that's about $37, $55 and $92 a year.
Can a Bitaxe Naja Duo make money?
Almost certainly not. It's a solo "lottery" miner: it either finds a whole Bitcoin block (a huge reward) or nothing. As a rough illustration, on a 1,000 EH/s network it would find a block about once every 4,300 years on average, while electricity costs money every year. Buy it as a hobby, not an investment.
