The number of wallet addresses holding more than 1,000 bitcoins (about $43 million) has reportedly surged as Western countries tighten sanctions on the Russian government and wealthy elites. According to data tracked by analytics site Coin Metrics, that number rose 7 percent to 2,226 on Feb. 28. The highest since June 2021. In addition, the number of addresses storing more than 100 bitcoins also increased, albeit a minor increase of 1.3%, bringing the total to 15,953. Block Research data shows a slight increase in the number of addresses with Bitcoin balances over $1,000, $10,000, $100,000, $1 million, and $10 million. But according to the data, the most prominent wallets are growing the fastest.
