Bitcoin surged to a fresh all-time high above $111,000 on Wednesday, as institutional inflows and macroeconomic tailwinds continued to fuel investor appetite for the world’s largest crypto. The rally, which has seen Bitcoin gain more than 18% since the start of May, was underpinned by steady demand for U.S.-listed spot Bitcoin exchange-traded funds.  Net inflows into the products have surpassed $2.8 billion this month, lifting total ETF holdings to over $122 billion, according to eToro Australia analyst Reece Hobson. “Bitcoin’s surge to an all-time high of $110,000 stems from multiple catalysts,” Hobson said. “Institutional inflows, particularly through U.S. spot bitcoin ETFs, have pumped billions into the market, while the April halving has tightened supply.” Analysts say macro conditions have also played a role, including growing liquidity, a weakening U.S. dolla,r and renewed geopolitical uncertainty. Still, attention is beginning to shift toward whether the latest breakout could set the stage for renewed strength in altcoins, which have largely underperformed in the current cycle. “Alt season will kick off when two key events align,” Hobson said. “Quantitative easing must begin, injecting more liquidity into the system, and Bitcoin dominance needs to hit around 70%.”  Bitcoin dominance, a measure of the asset’s market share, currently hovers near 61%, according to CoinGecko. Mena Theodorou, co-founder of Australian exchange Coinstash, said a broader altcoin rally remains unlikely in the near term, citing the ongoing price discovery phase in Bitcoin. “As Bitcoin continues into price discovery, it tends to absorb much of the market’s liquidity,” she said. “We’re more likely to see strength appear in select altcoins and sectors, rather than a broad-based rally.” Despite Ethereum’s sluggish performance, newer tokens such as Solana and Sui have outpaced it, with investors rotating into platforms offering scalability and developer traction. “Bitcoin’s driving the market narrative,” Hobson said. “It’s the Bitcoin show until the alt season kicks in.”
