Bitcoin Futures Open Interest and US Spot ETFs Turn Bullish as BTC Hits $74,000 on March 4

Bitcoin climbed from $68,000 to about $74,000 on March 4, setting a new monthly high as derivatives metrics and US spot ETF flows shifted bullishly. Analyst Amr Taha highlighted a sharp jump in futures open interest led by Binance and noted that spot ETFs accumulated roughly 23,600 BTC between February 25 and March 5. Another analyst, Maartunn, pointed to a widening Coinbase premium and rising leverage, suggesting strong institutional demand but also an increased risk of volatility if spot buying slows.
