According to the source, TheMinerMag reports the Bitcoin (BTC) network hashrate reached roughly 1 zetahash per second in 2025, advancing from gigahash levels in 2010 to exahash in 2016 as documented by TheMinerMag. For traders, a sustained hashrate high implies upward pressure on mining difficulty at the next 2016-block retarget, which mechanically lowers BTC-denominated revenue per unit of hashrate if price and fees are unchanged, according to Bitcoin protocol documentation and Luxor Hashrate Index methodology. This margin compression tends to advantage low-cost miners and weigh on high-cost operators and hashprice-linked instruments, according to Cambridge Centre for Alternative Finance and Luxor Hashrate Index. Higher aggregate hashrate raises the cost of a 51% attack and strengthens network security, a factor monitored by long-horizon investors during volatility, according to Cambridge Centre for Alternative Finance. Key trading watchpoints include upcoming difficulty estimates, miner BTC flows to exchanges, and fee levels as primary drivers of miner revenues and potential supply, according to Bitcoin protocol documentation and Glassnode analytics.
