Pricing
Six plans, or any amount in between. Every estimate here is live from the Bitcoin network, changes daily and is paid in bitcoin.1
Sale · every plan, any amount
Same hashrate. Same 24 months. Same pool payouts to your own wallet. Only the price is lower, and that lowers the bitcoin price a plan needs to pay back.
Runs from the start date to the end date, shown in your time zone. The sale price is applied at checkout with no code, to every plan and any custom amount, for new and returning customers alike. It doesn't combine with a welcome-wheel code: the larger discount applies. A lower price doesn't change what mining pays: estimates are still live and not guaranteed, and a plan can still pay back less than it costs. Risk disclosure.

Our largest plan: the hashrate of about forty S21 XPs, with every machine's serial number listed in your rights agreement.
Mining rights pay what your hashrate mines; they're not a fixed return. Estimates use today's price and difficulty and include the 2028 halving. Estimates change with the network every day and a plan can pay back less than it costs, so run the calculator first. "Power you skip" compares our 5.0¢/kWh with the 2026 U.S. home average of 18.2¢/kWh.2 Plans aren't offered in every country.
With mining rights you never run a machine, so you never pay to power one. We buy electricity at an industrial rate, and it's already in your price.

Mining rights only make sense if they get you bitcoin cheaper than buying it. This model starts from live hashprice, includes the 2028 halving, and gives you a straight answer either way.
Our honest verdict
Buy instead.
These mining rights would cost about $1.46 for every $1 of bitcoin they pay you. At these settings, simply buying bitcoin is about 31% cheaper. We'd rather lose the sale than your trust.
Yes. Spark is $100 for about 3.4 TH/s of mining rights for 24 months, and plans go up to $100,000 online, or any amount in between. Payouts vary with Bitcoin's price and network difficulty, so a plan can pay back less than it costs.
Power at our rate of $0.0023 per kWh is included in every plan. Running the same hashrate at home at the 2026 U.S. average of 18.2¢ per kWh would cost about 79 times as much. For a $1,000 Core plan that's about $4,580 of home electricity over 24 months, against about $58 of ours that's already in the price. At today's hashprice, mining at U.S. home rates costs more in power than it earns.
At November 2026 levels, about $0.032 a day before the pool fee, or roughly 42 sats. A $100 Spark plan's 3.4 TH/s earned about $0.11 a day. These numbers move every day with Bitcoin's price and network difficulty, and the 2028 halving will roughly halve them.
It depends on the power price, the machine's efficiency and Bitcoin's price. In November 2026 hashprice was about $0.032 per TH/s per day, so a 13.5 J/TH machine broke even at roughly $0.096 per kWh. Below that it earns a margin today, but the 2028 halving will cut revenue roughly in half at the same price and difficulty. Run your own numbers in our calculator first.
At block 1,050,000, expected around spring 2028, the block subsidy drops from 3.125 to 1.5625 BTC. At the same Bitcoin price and difficulty, payouts from your rights roughly halve overnight. Our estimates and calculator include the halving.
Yes. If Bitcoin's price falls or difficulty rises, a plan can pay back less than it cost. Your rights also depend on Tallyhashs running the machines for the full term, and they have no resale value at the end. Only commit money you can afford to lose.
