Bitcoin held in miner-linked wallets increased by about 1,797 BTC over the seven days through October 31, the largest weekly rise in roughly six weeks. CryptoQuant data reported by TokenPost put the cohort's balance near 1.194 million BTC at the end of the period. The change indicates that more coins remained inside addresses classified as belonging to miners, although it does not prove that mining companies bought Bitcoin on the open market.

The reserve increase was modest but directionally notable

A gain of 1,797 BTC represents about 0.15% of the tracked balance. It is small relative to the roughly 1.194 million BTC held by the cohort, but it marks a break from weeks when outflows or flat balances dominated. Miner reserves rise when rewards and incoming transfers exceed coins moved out of labeled wallets. Bitcoin's current block subsidy is 3.125 BTC, implying roughly 450 BTC of new issuance per day when blocks arrive near their ten-minute target. The reserve change is not the same as weekly production because labeled wallets can also receive older coins or transfers from other addresses. It can mean operators retained more production, but it can also reflect transfers between known addresses or changes in how an analytics provider classifies wallets.

Hashrate eased from elevated levels

Over the same week, Bitcoin's seven-day average hashrate fell by about 12.45 exahashes per second to approximately 1.053 zettahashes per second, TokenPost reported. Hashrate estimates the computing power devoted to securing the network and competing for block rewards. A weekly decline can reflect machines being switched off, changes in mining economics or ordinary measurement variation. Bitcoin recalibrates mining difficulty every 2,016 blocks, approximately every two weeks, to keep block production near its target pace. The network therefore absorbs short-term changes through a scheduled adjustment rather than relying on a fixed amount of computing power. The weekly decline does not, by itself, indicate a threat to network security.

CryptoQuant's earlier reading adds context

CryptoQuant said on October 28 that miner reserves were still only at the 13th percentile of their range over the previous year, while hashrate stood at the 81st percentile and mining difficulty had reached a six-month high of 140.6 trillion. The firm also observed that miner transfers to Binance were low relative to the prior year. Taken together, those readings show a network operating with substantial computing power while miner-held balances remained historically lean despite the latest weekly increase.

Wallet labels are estimates, not company accounts

On-chain miner metrics depend on clusters of addresses attributed to mining pools and their participants. CryptoQuant's documentation warns that historical reserve values can change as it discovers and validates additional miner wallets. The balance is therefore not equivalent to audited treasury disclosures from listed mining companies, and it cannot reveal why a particular operator moved coins. A transfer away from a labeled wallet is also not automatically a sale; coins can be pledged, lent, moved to custody or sent to another address.

What the market can watch next

The latest data show retention increasing while hashrate softened slightly, but neither measure predicts Bitcoin's next price move. A sustained reserve build would provide stronger evidence that miners are limiting distributions, while renewed outflows could reverse that interpretation quickly. Future difficulty adjustments, mining-company earnings and transfers from miner wallets to exchanges will help clarify whether the one-week change reflects a durable shift or a short-lived balance movement.
