Every miner on the network shares the same daily pool of bitcoin. When total network hashrate grows, each machine’s share shrinks, even if nothing about the machine has changed. That makes hashrate growth one of the biggest forces on how long your fleet stays profitable.
Sometimes hashrate races ahead of bitcoin’s price. Sometimes it lags far behind. Understanding why helps you judge how much life your current machines have left.
How hashrate reaches your revenue
Bitcoin adjusts mining difficulty every 2,016 blocks, roughly every two weeks, so that blocks keep arriving about every ten minutes. When more hashrate joins, difficulty rises and every terahash earns less. As a rule of thumb, 10% more network hashrate means about 10% less bitcoin for each machine.
So a machine’s earnings depend on two races: bitcoin’s price against your costs, and your hashrate against everyone else’s.
What makes hashrate grow fast
- High hashprice. When each terahash earns well, operators buy machines and plug in everything they have. Strong margins pull new capacity onto the network within months.
- Plenty of new machines. A new generation with a big jump in efficiency, plus manufacturers with spare production capacity, can add hashrate very quickly.
- Power ready to use. Sites with energised power, transformers and cooling already in place can deploy machines in weeks rather than years.
- Cheap capital. When money is easy to raise, large operators expand aggressively.
What holds it back
- Machine supply. New miners depend on advanced chip production, which competes with other industries for the same manufacturing capacity. Lead times can stretch for months.
- Power and infrastructure. New grid connections, substations and large transformers can take a year or more to arrive. Hashrate cannot grow faster than sites can be built.
- Retirement of older machines. As new models join, older ones fall below their shutdown price and switch off, which offsets part of the growth.
- Curtailment and seasons. Many sites switch off during grid peaks, summer heat or dry seasons for hydro power, so hashrate also swings through the year.
- Margins and regulation. Thin hashprice slows purchases, and policy changes in a mining region can take capacity offline quickly.
Reading the gap between price and hashrate
When bitcoin’s price rises faster than network hashrate, each terahash earns more and existing fleets enjoy wider margins. That window lasts until new capacity catches up. When hashrate rises faster than price, margins tighten and the least efficient machines are pushed out first.
Watching both numbers together is more useful than either alone. Hashprice combines them into a single figure — see What Is Hashprice?
What slow growth means for your fleet
When hashrate grows slowly, machines you already own stay competitive for longer. A model that might have been retired in two years can keep earning for three or four. That changes how to look after it:
- Repair rather than replace. A longer useful life makes a hashboard repair or a new power supply easier to justify — see Hashboard Repair or Replacement.
- Uptime is worth more. Every day a machine sits waiting for a part is a day of good margin lost. Keeping common spares on hand pays back faster — see Cheap Part, Expensive Downtime.
- Plan replacements around the halving. Slow growth helps, but the next halving still cuts revenue in half on a fixed date — see Bitcoin Halving and Miner Economics.
What fast growth means
When hashrate grows quickly, older machines reach their shutdown price sooner. Decide early which units to run, tune, move to cheaper power or retire, while they still have resale value — see what to do with old ASIC miners.
