Brian Armstrong, CEO of Coinbase, dismissed concerns over Bitcoin miners shifting to artificial intelligence on July 20, emphasizing that the network’s difficulty adjustment ensures consistent block production regardless of hash rate fluctuations. "Hash power or energy going to Bitcoin mining doesn’t determine its price," Armstrong stated on X, highlighting the protocol’s ability to self-correct when mining power decreases.
The Bitcoin network recently saw a 7.9% decline in hashrate over ten days, dropping to 908 EH/s, which triggered a 5% difficulty reduction to 127.17 trillion on July 11, marking the 14th adjustment of 2026. This mechanism makes mining puzzles easier when miners leave, maintaining an average block time of ten minutes. The difficulty reset raised the hashprice, miners’ revenue per unit of computing power, by 12.5% to $31.1 per PH/s, though this remains 37.2% below the peak seen in October 2025.
Armstrong’s remarks came in response to billionaire investor Chamath Palihapitiya’s argument that Bitcoin bulls face two challenges: speculative liquidity moving towards prediction and equity markets, and mining energy potentially being more valuable for AI applications. Armstrong called the first challenge temporary and rejected the second’s impact on Bitcoin’s price, stressing that demand factors outside of mining power primarily influence valuation.
In June, Armstrong identified $60,000 as Bitcoin’s price bottom. Despite some disagreement 56.3% of approximately 27,000 participants in a July 14 poll opposed this view the Coinbase CEO reaffirmed his bullish stance, remaining long on Bitcoin. His position shows confidence in the network’s resilience despite shifts in mining activity and market speculation.
