Risk disclosure
Mining rights can lose money. Here is every major way it can happen, in plain language, so nothing surprises you later.
Not a fixed return
Mining rights have a fixed price and a fixed term, but their payouts are not fixed. Our estimates use today's Bitcoin price and difficulty and include the 2028 halving, which cuts revenue roughly in half. If Bitcoin's price falls or difficulty rises faster than that, a plan can pay back less than it cost.
Bitcoin's price
You pay for your rights in advance, and payouts arrive in bitcoin. If Bitcoin's price falls, the dollar value of your payouts falls with it.
Network difficulty
As more machines join the network, difficulty rises and each TH/s earns less bitcoin. Difficulty has risen sharply in some years and can rise again at any time.
The halving
At block 1,050,000, expected around spring 2028, the block subsidy halves from 3.125 to 1.5625 BTC. At the same price and difficulty, payouts roughly halve.
No ownership, no resale value
You own rights, not hardware. When the term ends your rights end, and there's nothing left to keep or sell.
Counterparty risk
Your rights depend on Tallyhashs running the machines for the full term. If we fail, become insolvent, or lose access to power or our facility, payouts could stop early and you might not get your money back.
Downtime
Machines fail, need repairs and can be curtailed by the grid. Downtime reduces what your hashrate mines.
Power and regulation
Electricity tariffs, permits and mining rules can change. Some jurisdictions have raised tariffs or paused new permits in recent years. Changes like these can force relocation or shutdowns.
Mining in Iceland
Our machines run in Iceland, where the power is hydro and geothermal and depends on rainfall, snowmelt and the grid. In dry years Iceland's national power company has cut supply to large users, data centres included (in 2021 and again in 2024), and it has said it is reducing the power it sells to cryptocurrency mining. The Reykjanes peninsula has had repeated volcanic eruptions since 2021, some close to power plants. Any of these can reduce or stop the hours your hashrate mines, or force us to move machines.
Regulatory status
Rights to mining profits may be regulated as securities in some countries. Regulators could restrict their sale or require changes to how they work.
Custody
Payouts go to a Bitcoin address you control. If you lose your keys, or send payouts to an address you don't control, those funds can't be recovered by anyone, including us.
Models and comparisons
Our calculator, live estimates and "power you skip" comparisons are illustrative models based on public network data and stated assumptions, including a U.S. average home electricity price. They are not forecasts, promises or financial advice.
Tax
Mining payouts are usually taxable where you live, including when they're paid in bitcoin. We don't provide tax advice; speak to a qualified adviser. See how mining payouts are taxed.
