Bitcoin Pulls Ahead: Dominance Jumps as Macro Tailwinds and Shorts Fuel a 24% Weekly Surge

Bitcoin’s latest leg isn’t just another green candle—it’s a repricing of risk. Up roughly 24% on the week to trade near $79,000, Bitcoin is on pace for its strongest run since 2023, and its dominance briefly hit about 61% before easing to roughly 59%, close to year highs. That’s the tell: when the benchmark outpaces the field and dominance rises, capital is choosing liquidity and settlement assurance over speculative breadth.

The alt picture is more nuanced than a simple lag. Ethereum led the pack, climbing about 30% over the same stretch to above $2,500. But the broader complex failed to follow through. Total2—the index of all crypto ex-Bitcoin—jumped more than 24% between August 19 and 22, reclaiming $1 trillion, then surrendered part of the move and now trades near $1.05 trillion, down over the last two sessions as Bitcoin kept climbing. Total3, which strips out both Bitcoin and Ethereum, cooled after an early burst and sits around $753 billion, down on the week even as BTC pressed toward $80,000. The CoinMarketCap Altcoin Season Index reads 46—well shy of the 75 threshold that signals true alt season (25 typically marks a Bitcoin-first regime).

What flipped the switch was policy and positioning. The U.S. Treasury said it will double long-bond buybacks—from $2 billion to $4 billion per operation starting September 9—supporting demand for duration and softening the dollar. That macro shift favored inflation hedges, the same dynamic helping gold notch records this year, and it sharpened Bitcoin’s bid. Two days later, President Donald Trump met crypto executives at the White House and pushed Congress to advance the Clarity Act, legislation meant to settle which U.S. regulator oversees which crypto assets. As Bitcoin broke through $70,000, shorts scrambled: more than $4 billion in crypto short positions were liquidated over two to three days, per Bitget Wallet research analyst Lacie Zhang—classic fuel for a vertical move.

Focus on dominance to understand why altcoins aren’t running. In risk-off-to-neutral transitions, allocators often consolidate into the asset with the deepest liquidity, clearer regulatory path, and the strongest collateral profile. Bitcoin fits that bill; many altcoins still carry higher execution and regulatory risk, which blunts follow-on flows until conviction broadens. The Altcoin Season Index stuck at 46 reflects that psychology. Business constraints matter, too: compliance-driven mandates tend to greenlight BTC well before they extend to the long tail. Ethically, durable policy clarity—if the Clarity Act advances in the Senate in mid-September—could normalize access and reduce the advantage held by the best-capitalized market participants, setting the stage for a more even dispersion of returns later.

Technically, a sustained break above $80,000 can open a path toward $82,000 to $87,000, while $75,000 to $76,000 remains the primary pullback zone. Until dominance decisively rolls over and the Altcoin Season Index climbs toward the mid-70s, rallies in the long tail may stay sporadic.
