If it feels like something is brewing beneath the surface of Bitcoin, you’re not imagining things. According to data from Glassnode, Bitcoin wallet stats show that wallets holding between 100 and 1,000 BTC (the so-called “shark” cohort) have hit an all-time high.
Every time this kind of accumulation takes place, it makes Bitcoin news, and the BTC price tends to soar. Could there be a pump incoming?
Is BTC Price About to Explode Thanks To Historic Levels of Wallet Growth?
What’s behind the frenzy? Are the sharks onto something, or are we all just witnessing a garden-variety migration with a little Twitter hype thrown in for fun?
On-chain trackers don’t lie. Glassnode’s data shows historic levels in Bitcoin wallet growth.
Further, it displays marked increase in aggregate holdings for addresses containing 100–1000 BTC. At the current Bitcoin price, that’s roughly $11 million to $110 million per wallet.
Over the past week, their holdings grew by around 65,000 BTC. The pace of accumulation has grown as well. A 30-day net increase of 93,000 BTC to reach a record 3.65 million BTC.
Why does that matter? Well, in every previous cycle (think 2020, 2017, and even 2013), heavy accumulation by shark wallets preceded massive bull runs.
It affected BTC price to the upside as an increasing number of coins are sidelined into cold storage and the liquid supply ready to sell keeps trickling away.
Supply Squeeze: Exchanges Running Dry
Ask any chartist what sends BTC price vertical. They’ll paint you a simple economic picture: when demand outstrips supply, prices run. Except this year, it’s not just theory, it’s happening in real time.
Supply on exchanges is sitting at its lowest level in years. By summer 2025, the total BTC held on centralized trading platforms dropped below 2.1 million coins.
That’s less than 10% of the circulating supply and down from over 3 million just two years ago.
That means there are fewer coins available for traders and more being locked up by sharks, whales, funds, and treasuries.
This tightening float coincides with relentless demand from newly launched Bitcoin ETFs. BlackRock’s IBIT alone now manages over $86 billion in assets. Total spot ETF inflows in Q3 2025 reached $118 billion.
These new buyers aren’t day traders. ETFs anchor long-term demand, and they’re vacuuming up supply faster than daily mining can replenish it.
In Other Bitcoin News: Hash Rate Moon Mission
It’s not just wallets and exchanges setting records. As of mid-September, Bitcoin’s hash rate smashed previous records, often cited as the “ultimate” bullish fundamental.
High hash rates mean miners are investing heavily. That tends to correlate with price optimism (not to mention securing the protocol for years to come).
This perfect storm, less liquid supply, more institutional buying, and surging hash rates, is exactly the kind of setup that typically sends BTC price up and to the right.
Add to that companies like MicroStrategy continuing to add BTC to their treasuries, and the massive withdrawal of coins from trading venues, and we could be in for explosive action ahead.
Every indicator that matters for BTC price, from shark wallets and institutional inflows, to record hash rate and vanishing supply, has never looked quite this bullish.
The last time things lined up so perfectly, a dearth of supply and a wall of new buyers sent BTC soaring to new historical highs.
So as the sharks load up and supply tightens, don’t be surprised if history rhymes. The stage is set, the cast is ready, and now, all eyes are on the next act.
If the past is any guide, those 100–1000 BTC wallets know the script better than anyone else.
