The number of Bitcoin addresses holding over $1 million increased by 26,758 in the first half of 2025, reaching a total of 182,327 by June 30. This growth was driven by strong buying during market dips and renewed institutional demand following the launch of U.S. spot Bitcoin ETFs. The April 2025 Bitcoin halving event also contributed to bullish sentiment, with Bitcoin peaking at $111,970 on May 22, 2025. While not all addresses represent unique individuals, the rise indicates significant accumulation by wealthy investors and firms.
