Sazmining opens sales of Proto mining boards to private Bitcoin miners

what happened

Sazmining, a mining-as-a-service provider based in Wyoming, has started offering Proto immersion hashboards directly to individuals, according to Crypto Briefing. The boards, developed by Block, had previously been sold mainly to large mining operators. Each unit delivers about 204 TH/s at 15 J/TH, which works out to roughly 3,060 watts of draw. Cooling relies on a non-conductive liquid instead of fans.

The price starts at $4,187, or $3,978 for buyers paying in crypto. A financing option requires $1,397 upfront and 18 monthly payments of $155 at 0% interest, which adds up to the same $4,187. On top of the hardware, Sazmining keeps a 15% fee on the bitcoin each board mines, and passes electricity costs to customers at about $0.063 per kWh. Under current conditions, the payback could take more than six years.

Bitcoin's network hashrate has climbed back above 1,000 EH/s, reaching about 1,076 EH/s by October 30, 2026, with difficulty at 148.36T. Ivo Georgiev, founder and CEO of the wallet company Ambire, who started mining in 2011, said: "It's still hard to make money as an individual miner, and it's not going to get any easier."

why it matters

For a miner, revenue depends on the BTC price and network difficulty, while costs come from electricity, Sazmining's fee and the purchase price of the hardware. Each halving cuts the block reward in half, so with the network unchanged, income per unit of hashing power falls and payback stretches even further. The next halving is expected roughly 76,000 blocks from now.
