What would this coin earn you?
How this coin is mined
A Bitcoin fork that switched its proof-of-work to Blake2b at block 961,640 (30 Aug 2026), so the Blake2b ASICs built for Siacoin mine it. It keeps Bitcoin's 3.125-coin reward and 10-minute blocks. Price comes from the NonKYC exchange, network hashrate from the public BTCB2 explorer.
Mining this coin: FAQ
Is Bitcoin BLAKE2b mining profitable right now?
At 5¢/kWh the most profitable Bitcoin BLAKE2b miner today, the iBelink BM-S3+, earns about $141.19 a day and burns $4.08 of electricity, leaving about $137.11 a day. 14 of 14 Blake2b-Sia miners we track are profitable at that price. Set your own power price above and the whole page recalculates.
What is the best miner for Bitcoin BLAKE2b?
Ranked by profit per day at 5¢/kWh: iBelink BM-S3+ ($137.11/day, 25 TH/s at 3,400 W), iBeLink BM-S3 ($103.59/day, 19 TH/s at 3,100 W), Goldshell SC6-SE ($92.05/day, 17 TH/s at 3,300 W). The most efficient machine we track is the iBelink BM-S3+ at 136.0 J/TH; cheap power favours raw hashrate, expensive power favours efficiency, so the order changes with your price.
At what electricity price does Bitcoin BLAKE2b mining stop paying?
At today's price and difficulty the iBelink BM-S3+ breaks even at about $1.73 per kWh: above that it costs more to run than it earns. Pool fees (usually 1-4%), cooling and any hosting margin come on top, so plan with a buffer. Of the 14 machines we track, 14 are in profit at 3¢/kWh, 14 at 6¢ and 14 at 10¢, which is why miners chase cheap power.
How long does a Bitcoin BLAKE2b miner take to pay for itself?
The fastest payback at 5¢/kWh is the iBeLink BM-S1 Max: about $4,599 for the machine, $63.99 profit a day, so roughly 2 months if price and difficulty stayed where they are today. The top earner, the iBelink BM-S3+, costs $13,999 and pays back in about 3 months. In practice difficulty usually rises as new machines ship, so real payback is longer; a falling coin price stretches it further, a rally shortens it.
How much BTCB2 does one miner make per day?
The iBelink BM-S3+, at 25 TH/s, mines about 0.231 BTCB2 a day today, worth $141.19. That is 0.051% of the network's 48.64 PH/s. The whole network mints about 450.0 BTCB2 a day ($274,730), and every miner earns its share of hashrate.
Should I mine Bitcoin BLAKE2b solo or in a pool?
On its own, one iBelink BM-S3+ would find a Bitcoin BLAKE2b block about once every 14 days on average, and luck can stretch that a long way. With blocks this frequent, even a single machine gets regular rewards; pools still smooth the payouts. FPPS and PPS+ pools pay a fixed amount per share (fees often 2-4%), PPLNS pools pay out only when the pool finds a block (often 0-2%, but lumpier).
How do Bitcoin BLAKE2b's block rewards and supply work?
Right now each block pays about 3.125 BTCB2 including fees, with a block every 10 minutes on average, about 450.0 BTCB2 a day. 20.12 million of the 21.00 million maximum are already out (96%). It kept Bitcoin's schedule after the fork: 3.125 coins per block, roughly one block every 10 minutes, and halvings every 210,000 blocks.
What hardware mines Blake2b-Sia, and what matters when buying?
Blake2b-Sia is Sia's version of the Blake2b hash. It is cheap to compute, so dedicated ASICs (Goldshell, iBeLink and others) took over early. Since 30 August 2026 the same machines also mine Bitcoin BLAKE2b, so hashrate moves between the two coins whenever one pays more. We track 14 Blake2b-Sia machines; judge them by J/TH (efficiency) against your power price, then by price per TH, cooling type and the warranty and repair options where you will run them.
What does a 1 MW Bitcoin BLAKE2b mining site earn?
One megawatt of power runs about 294 iBelink BM-S3+ units. At 5¢/kWh that is roughly $1.23M a month in profit before pool fees, cooling overhead and staff, for about $4.12M of machines. That fleet would add about 15% to the network's hashrate, so once difficulty catches up every machine earns roughly that much less. Site profit is very sensitive to the power price: every 1¢/kWh costs about $7,296 a month at one megawatt. CryptoSites.io lists powered land, container farms and hosting with the power price on every listing.
How do I start mining Bitcoin BLAKE2b?
Pick a machine for your power price (see the table above), then sort out power and cooling: most ASICs need 200-277 V at 10-30 A each, hydro models usually 380-415 V three-phase and a cooling loop, and air-cooled units are too loud for a home. Set up a Bitcoin BLAKE2b wallet, point the machine at a pool, and watch temperatures in the first days. If you don't have cheap power and space, hosting is the usual route: a host runs the machine for an all-in price per kWh. CryptoSites.io lists both powered sites and hosting.

NewBitcoin Difficulty Is Down 15% From Its Peak. Should You Buy a Mining Site Now?
Lower difficulty means each machine earns more bitcoin. But difficulty follows hashrate, and hashrate can come back fast. Here's how to price a site on a range, not on today's number.

Where the World's Hashrate Is Moving in 2026 (and What It Means for Site Prices)
The network stopped shrinking in Q3 2026, but the map underneath it is still changing fast. Developed markets are giving up hashrate to AI, while a group of energy-rich countries keeps absorbing new machines.

Hashprice Near $40: Which Mining Sites Still Make Money (and Which Owners Will Sell)
At about $40 per PH per day, a fleet's efficiency sets a hard ceiling on the electricity cost it can afford. Here's where that ceiling sits, who is under pressure, and what it means for anyone buying a site.
