All specific figures in the claim - 74.536 BTC added, $5.93 million value, 3,389 BTC total holdings, ~$273 million total value, and Arkham as the data source - are consistently confirmed across multiple independent outlets including Odaily, KuCoin, and Bitget, all published on May 16, 2026. No conflicting data was found. The slight uncertainty (7%) reflects the fact that the ultimate primary source is Arkham's on-chain monitoring dashboard, which was not directly fetched, and that MSBT is a relatively new product with limited direct regulatory filings available for cross-check.
