"Hash rate is the heart rate of the Bitcoin network. When it's beating at all-time highs, the patient is not just alive — it's thriving."
Welcome back to the HODLer Wisdom newsletter. This week, we turn our attention to one of the most underappreciated signals in Bitcoin: the hash rate.
In September 2025, Bitcoin's network hash rate hit an all-time high of 1.12 billion terahashes per second. Most news outlets buried this. Financial media was fixated on short-term price movements. But for long-term thinkers, this milestone deserves serious attention.
Hash rate is the total computational power being applied to secure the Bitcoin network at any given moment. Every miner on Earth — from warehouse-scale operations in Texas and Kazakhstan to small home setups — contributes to this number.
Each "hash" is a lottery ticket: a guess at the random number needed to produce the next valid block. At 1.12 billion terahashes per second, the global Bitcoin mining ecosystem is making over a quadrillion guesses every second. This relentless computation is what makes Bitcoin's transaction history immutable.
Hash rate is easy to dismiss as a technical metric. But it's actually one of the most important fundamental indicators available to long-term Bitcoin investors. Here's why:
Mining at scale requires purchasing ASICs — purpose-built machines that cost $2,000–$10,000 each and are worthless for any other purpose. They require data center infrastructure, cheap electricity contracts, and ongoing operational expertise. Industrial miners typically model 3–5 year payback periods when they make these investments.
When hash rate hits all-time highs, it means rational, sophisticated economic actors have committed billions of dollars in capital to Bitcoin — with the expectation of profitability over a multi-year horizon. This is the ultimate long-term price signal.
To perform a 51% attack on Bitcoin — to rewrite recent transaction history — an attacker would need to control more than half the network's hash rate, sustained over time. At 1.12 billion TH/s, the hardware alone for such an attack would cost tens of billions of dollars, and the electricity would cost millions per hour.
Bitcoin has never been successfully attacked at the protocol level. As hash rate grows, it becomes increasingly impossible. This security is the foundation of everything: it's why Bitcoin can be a credibly neutral store of value that no government, company, or individual can unilaterally debase or confiscate.
The April 2024 halving cut miner rewards from 6.25 to 3.125 BTC per block. Halvings always create short-term pressure on miners — those with inefficient hardware or high electricity costs get squeezed out. Hash rate typically dips briefly post-halving as marginal miners exit.
The fact that hash rate has already surpassed pre-halving levels and hit new all-time highs tells us two things: first, the post-halving miner shakeout is complete; second, the economics of mining at current prices and efficiencies remain strongly positive. This is precisely what happened after the 2020 halving.
A thoughtful HODLer should steelman the opposing view. What could high hash rate signal that isn't bullish?
Miner capitulation risk: If the Bitcoin price falls significantly while hash rate stays high, miners' revenues decline while costs remain fixed. This can trigger forced selling of mined BTC to cover operational expenses — creating short-term sell pressure. However, this also triggers a self-correcting mechanism: less profitable miners exit, hash rate drops, difficulty adjusts down, and surviving miners become more profitable.
Centralization concerns: Hash rate concentration in fewer, larger operations could theoretically increase centralization risk. In practice, the geographic distribution of mining has become dramatically more diverse post-China ban — with major operations now in the US, Canada, Russia, Scandinavia, and Central Asia.
On balance: hash rate at all-time highs, with the post-halving adjustment behind us, is an unambiguously positive long-term signal.
Every four years, the block reward halves. Every four years, hash rate has continued to grow regardless. By the 2028 halving, the block reward will fall to 1.5625 BTC. By then, Bitcoin's price must be meaningfully higher than today for mining to remain economical — or transaction fees must fill the gap.
This is not a problem. It's the design. The halving schedule creates a programmatic supply squeeze that has historically preceded Bitcoin's largest price appreciation cycles. The 2024 halving was no different — it set the stage for the next chapter.

When you hold Bitcoin, you hold a share of the most secure, decentralized, auditable monetary system ever created — one that is being actively secured by hash rate records. That is the HODLer's position.
