BlackRock IncBlackRock's iShares Bitcoin Trust ETF holdings are cited as a key driver of long-term holder supply increase, indicating strong product demand.

The net position change of Bitcoin long-term holders, measured on a 30-day cumulative basis, has reached one of the largest positive levels on record. According to data from CryptoQuant, the 30-day net increase reached approximately 1.29 million BTC in May 2026, marking one of the largest increases in at least the past six years. This surge is largely due not only to recent buying, but also to Bitcoin acquired months ago through spot ETFs, institutional investors, and corporate treasuries that has been held for roughly 155 days or more without being sold, thus becoming classified as long-term holder supply. In particular, BlackRock's iShares Bitcoin Trust ETF held approximately 739,000 BTC as of July 23, 2026, and such ETF holdings have boosted long-term holder supply. XWin views this development as a positive structural change that could lead to medium- to long-term supply compression, while noting that confirming a short-term price rally requires assessment alongside other indicators such as ETF flows and exchange inventories.
