Bitcoin Whales Buy $23B in BTC in Largest Accumulation Since 2011

Onchain data shows Bitcoin’s largest holders are quietly accumulating at historic levels. Over the past 30 days, whales and large investors have added 269,822 BTC, worth roughly $23.3 billion, marking the biggest monthly accumulation in more than 13 years, according to Glassnode.

Most of the buying came from wallets holding 100–1,000 BTC, suggesting both wealthy individuals and smaller institutions are positioning for a longer-term move. Some analysts believe this behavior points to a shift away from the traditional four-year cycle and toward a potential “supercycle,” driven by sustained institutional demand.
