Bitcoin just posted one of its best weekly performances since 2020, climbing roughly 25% in late August to touch highs around $80K. Spot ETFs are vacuuming up capital. Exchanges are swimming in volume. Stablecoin dominance is cracking. And the companies that literally produce Bitcoin for a living? They’ve been too busy selling their coins and building data centers to enjoy the ride.
Public Bitcoin miners offloaded between 28,000 and 32,000 BTC during the first half of 2026, a stash worth approximately $1.78 billion at the time. Much of that selling funded a strategic pivot toward artificial intelligence and high-performance computing, with miners collectively committing over $70 billion to those sectors.
The rally everyone else showed up for
The numbers tell a clean story of capital rotating hard into risk assets. Spot Bitcoin ETFs attracted roughly $3.8 billion in net inflows over three weeks through early September, including a single-day surge of $731 million.
Meanwhile, stablecoin allocations within crypto portfolios dropped 22% during the rally period. The total crypto market cap swelled to nearly $2.7 trillion. Exchanges benefited directly from the heightened trading activity, with volumes climbing across major platforms.
One particularly telling signal: USDT dominance showed a potential “death cross,” where its 50-day moving average fell below its 200-day moving average, suggesting stablecoin dominance is weakening.
Why miners got left behind
The miner predicament is a case study in opportunity cost. Throughout H1 2026, the mining sector faced a punishing combination of depressed Bitcoin prices and rising operational expenses, where selling mined Bitcoin was less a strategy than a survival mechanism.
Hashprice jumped over 24% in August as Bitcoin’s price climbed. Some miners have begun borrowing against their remaining Bitcoin reserves rather than liquidating them, a shift that signals growing confidence in further upside.
Macro tailwinds and what comes next
The rally didn’t happen in a vacuum. US Treasury liquidity initiatives provided a macro backdrop that favored risk assets broadly. An overarching short squeeze amplified the move, and ETF inflows provided a steady bid underneath the market.
A consortium of 21 major financial institutions is reportedly planning to launch a new stablecoin venture targeted for 2027, which could draw fresh institutional capital into the broader crypto ecosystem.
The divergence between miners and the rest of the crypto sector highlights a recurring tension in the industry. Exchanges and stablecoin issuers, whose revenues scale directly with market activity, captured the rally’s upside almost immediately. Mining companies, locked into long-term infrastructure commitments and depleted of their Bitcoin treasuries, are structurally slower to benefit.
