On-chain data reveals a significant accumulation trend among Bitcoin's most steadfast investors, even as the market faces volatility. According to analysis shared by CryptoQuant community analyst Maartunn, the supply held by Bitcoin long-term holders (LTHs) has increased by approximately 332,600 BTC over the past month. LTHs are defined as investors holding their coins for more than 155 days, a cohort historically considered the market's "diamond hands."
This accumulation marks a sharp reversal from the latter half of 2025, where the LTH supply saw a negative monthly change, indicating distribution and selling, most intensely during a November crash. However, since January 2026, the LTH netflow has turned positive and has been climbing steadily.
It's crucial to note that an increase in LTH supply reflects accumulation that occurred roughly five months prior, as coins only enter this cohort after the 155-day threshold. This contrasts with selling, which instantly resets a coin's age. Nonetheless, the rising trend signals a growing tolerance for long-term holding among investors, particularly notable given ongoing market uncertainty linked to geopolitical tensions.
Supporting this narrative, analysis of UTXO Age Bands data shows the current cycle is structurally different from previous bull and bear markets. In past cycles, long-term holding bands expanded during rallies and then collapsed sharply during downturns as holders distributed coins. In 2025-2026, this pattern is absent; the share of coins held for six months and beyond has not compressed despite price pullbacks.
Two key structural factors explain this change. First, spot Bitcoin ETFs now hold significant amounts of BTC in cold storage, with institutional redemption mechanics insulating them from short-term price swings. Second, the adoption of digital asset treasury strategies by corporations means selling is governed by formal policy, not sentiment.
Adding to the institutional demand picture, Morgan Stanley has filed an amended S-1 with the SEC for its own spot Bitcoin ETF, MSBT. If approved, it would be the first major U.S. bank to issue such a product directly. Strategy CEO Phong Le has estimated that a mere 2% allocation across Morgan Stanley's $8 trillion wealth management platform could represent roughly $160 billion in potential Bitcoin demand—approximately three times the current size of BlackRock's IBIT fund.
At the time of reporting, Bitcoin was trading around $68,500, down more than 6% over the previous week, demonstrating that while long-term holder behavior suggests underlying strength, market volatility remains a present reality.
