Bitcoin's price dynamics are increasingly driven by global liquidity and monetary policy rather than its traditional four-year halving cycle, according to Arthur Hayes, co-founder of BitMEX. Hayes points to U.S. and Chinese credit expansion, ETF inflows, and institutional adoption as key factors influencing Bitcoin's valuation. Recent data from K33 Research supports this shift, showing a record 63,083 BTC added to ETFs in a single week. Hayes suggests that liquidity expansion, including U.S. Treasury bill issuance and potential Federal Reserve rate cuts, is bolstering Bitcoin's rally. He predicts that Bitcoin's price cycle will now align more closely with liquidity conditions, potentially extending the current bull run into 2026.
