Bitcoin whales freeze – Is BTC drifting toward $86.5K danger zone?

Bitcoin’s [BTC] pace has softened, and the market suddenly feels quieter than it has in months.

Big buyers aren’t adding much, long-term holders (LTH) aren’t selling heavily, and the price has slipped below key levels. We’re in a tight spot, and we could go sideways next.

Or… is this the start of something bigger?

The first sign of weakness

Bitcoin’s uptrend is losing strength, and here’s the first sign: the slowdown in dolphin balance growth (wallets holding between 100 and 1,000 BTC).

According to CryptoQuant’s Julio Moreno, these addresses added as much as 965,000 BTC year-over-year at the peak. At the time of writing, that growth has slipped to 694,000 BTC.

This cohort includes ETFs and public companies, meaning some of the market’s most influential buyers have paused their activity. When the very group that fueled the rally stops accumulating, it becomes harder for Bitcoin to climb higher.

For now, the strongest buyers are stepping back.

This slowdown comes at a time when corporate treasuries holding Bitcoin are under visible strain.

The combined market cap of major BTC‑heavy firms such as MSTR, Metaplanet, XXI, and others has dropped sharply, falling from around $152 billion in mid‑July to just $73.5 billion.

Despite that, these companies are holding their Bitcoin positions steady even as the market tests them.

OG sellers step back

Building on that slowdown, the OG cohort have also pulled back on their selling. The 90-day daily average of spent UTXOs from coins older than five years has dropped from roughly 2,350 BTC to around 1,000 BTC.

These coins were originally purchased for around $30,000, and when they move, it is typically to sell. With their activity now reduced, one of the market’s largest sources of selling pressure is beginning to ease.

Even more importantly, each cycle’s STXO peaks from this group are getting smaller, so LTHs are becoming less reactive as the cycle matures.

At a crossroads

With selling pressure cooling, the focus is now on where Bitcoin goes next… and the charts aren’t offering much comfort.

BTC has already slipped below the $89,800 level, a key zone many traders were watching closely.

According to Joao Wedson of Alphractal, losing this support raises the odds of a broader sideways phase, especially as Bitcoin also failed to hold important on-chain levels. The critical line now sits at $86,500.

If BTC breaks below it, Wedson warns the next stop could be $80,500. This move would be a new local low but could also set up a cleaner long for patient traders.

Final Thoughts

• Bitcoin is drifting into volatility, and the next move depends on whether $86,500 holds.
• Corporate treasuries sitting on $73.5B in underwater BTC could become the cycle’s wildcard.
