BlackRock's IBIT dominated with a $1.23 billion inflow, while Bitwise's BITB saw $29.85 million, Grayscale's Bitcoin Mini Trust $14.93 million, and Hashdex's DEFI fund $1.17 million.

Positive Market Sentiment Amid Easing Geopolitical Tensions

Having witnessed a 10‑day streak of ETF inflows, Bitcoin has been able to record this bullish run thanks to easing geopolitical uncertainty with the Iran-Israel ceasefire taking center stage.

BlackRock's IBIT dominance cannot go unnoticed because its inflows since early June have surpassed $2.6 billion, securing 9-concecutive days of inflows.

Therefore, the $1.02 billion net inflow reflects sustained institutional conviction, supply-driven bullish dynamics, and geopolitical stability with Bitcoin ETFs already cementing their place as a mainstream investment vehicles.

Meanwhile, Bitcoin and crypto funds have raked in inflows for 10 consecutive weeks, adding $1.24 billion recently and pushing year-to-date totals to $15 billion. Despite holiday lulls and global jitters, investors are seizing the pullback as a buying opportunity—not a sell signal.

Bitcoin attracted $1.11 billion in weekly capital inflows, boosting its monthly total to $2.37 billion and year-to-date haul to $12.7 billion—backed by nearly $152 billion in assets under management, according to CoinShares data

Therefore, these metrics paint a bullish Bitcoin picture as more institutional and retail investors continue jumping on the BTC bandwagon.

Bitcoin’s Illiquid Supply Ballons

Bitcoin’s illiquid supply—the portion of coins held in wallets that rarely move—is now 14.37 million BTC, up from roughly 13.9 million BTC at the start of the year, reflecting a rise of 470,000 BTC YTD.

This means over 72 percent of the circulating Bitcoin supply—approximately 19.8 million BTC—is now effectively “off‑market,” held by long‑term investors and cold wallets. That’s a historic peak in illiquid supply, driven by two reinforcing trends:

What’s Driving the Surge?

  1. Record Accumulation in Recent Months Over the past 30 days, around 180,000 BTC moved into illiquid wallets—the strongest monthly shift since December 2022.

“Whales & sharks” (entities holding 10–10,000 BTC) added 83,000 BTC, while small retail investors offloaded a few hundred.

  1. Institutions & ETFs Mopping Up Corporate treasuries and U.S. spot Bitcoin ETFs are absorbing newly mined BTC almost as fast as they’re released, sometimes even exceeding miner issuance. As a result, what little liquid supply remains is being hoarded or locked away.

 Why It Matters

  • Reduced sell‑side pressure: With fewer BTC on exchanges, sudden demand surges can trigger sharp price moves.

  • Heightened scarcity: As more coins become illiquid, a supply “squeeze” becomes increasingly likely, bolstered by the upcoming mining reward halving in 2028.

  • Maturing market: The shift toward long-term holding echoes Bitcoin’s evolution as a “digital gold” rather than speculative asset.

Outlook

This rising illiquid supply trend—a bellwether of investor conviction—may predispose Bitcoin toward sustained upward momentum. While cyclical pullbacks remain possible, fewer coins available for trading mean any demand spike might outsizedly impact price.

Conclusion

Bitcoin’s illiquid supply topping 14 million BTC underscores a market dominated by conviction, not speculation. 

With whales, institutions, and treasuries continuing to accumulate, the tightening float points to mounting scarcity, setting the stage for potentially bullish price dynamics in the months ahead.

This coupled with Bitcoin’s ETF and capital inflows going through the roof have the potential of sending the apex cryptocurrency to a new all-time high (ATH) above with the present price being $107,104.
