- Bitcoin whales have accumulated 270,000 BTC over the past 30 days, the largest wave of accumulation since 2013.
- Bitcoin reserves on exchanges have fallen to their lowest level since December 2017, tightening the amount of readily available supply.
Bitcoin largest holders appear to be buying again in size, and the pace is starting to stand out even by long-cycle standards.
According to CryptoQuant data cited by Bitfinex, whales have accumulated 270,000 BTC over the past 30 days, marking what the firms described as the strongest accumulation wave since 2013. At the same time, the amount of Bitcoin held on exchanges has dropped to its lowest level since December 2017, adding another sign that available supply is continuing to thin.
Whale buying is picking up while exchange supply shrinks
Those two trends together matter more than either one on its own. Whale accumulation can sometimes reflect quiet positioning by larger market participants, but when it happens alongside falling exchange balances, the message usually looks more directional. Coins are not just being bought. They are also being moved away from trading venues, which tends to reduce immediately liquid supply.
That does not guarantee a straight line higher in price, of course. Bitcoin has a habit of making even strong-looking supply signals wait longer than traders expect. Still, the setup is notable.
The CryptoQuant chart shared by Bitfinex adds another layer to that view. It shows larger order sizes clustering in periods that historically aligned with stronger long-term accumulation, while smaller retail activity often appeared more reactive during tops and pullbacks.
Market structure is starting to look tighter
If exchange reserves continue falling, the market may become more sensitive to fresh demand shocks. That is usually where supply-side narratives start to matter more. When fewer coins sit on exchanges and larger holders keep absorbing available Bitcoin, it becomes harder for the market to find easy liquidity without higher prices pulling sellers back in.
For now, the picture is fairly clear. Bigger holders are accumulating aggressively, exchange balances are thinning, and the broader structure looks tighter than it has in years. That does not remove volatility, but it does suggest the underlying supply backdrop is becoming harder to ignore.
