When Big Players Hold the Keys: Why Nearly a Third of Bitcoin in Few Hands Matters

Glassnode’s finding and what it means for markets

Glassnode’s latest on-chain analysis shows that almost a third of all Bitcoin is sitting with a relatively small set of holders — what analysts call “big players.” That group includes exchanges, custodial funds, corporate treasuries, government coffers and very large private wallets. The headline is simple: a lot of supply is not widely distributed.

Why that matters is also straightforward. When a small group controls a large share of supply, the way price moves and liquidity behaves can change. Large holders can pull liquidity from the market, or they can dump lots of coins at once. Both outcomes create bigger swings and make it harder for regular traders to predict short-term prices.

Who counts as a big player and how the supply breaks down

Glassnode groups addresses by type rather than by name. The main categories are exchanges (hot and cold wallets used for customer deposits and withdrawals), custodial funds and trust products, corporate treasuries that hold BTC as a balance-sheet asset, government-held coins (from seizures or official reserves), and very large private wallets often labelled as “whales.”

The firm’s headline number — nearly one-third of supply — is driven most by exchanges and custodial services. Those entities often hold many users’ coins together, so they show up as big addresses on-chain. Corporate treasuries are a noticeable slice too; public companies such as MicroStrategy (MSTR) have been long-time accumulators and sit in that bucket. Government holdings and a handful of ultra-large private wallets make up smaller parts of the total.

Glassnode doesn’t publish a neat pie chart that names every holder, but the rough picture is: exchanges and custodial services contribute the largest share of that near-30% total; corporate treasuries and institutional funds make up a meaningful middle; governments and whales fill out the remainder.

How concentration changes market dynamics now and in the near term

Concentrated ownership affects four things investors care about: liquidity, price discovery, volatility and on-chain signals.

Liquidity. When lots of BTC is parked with a few custodians, visible market liquidity can look deeper than it actually is, because much of that supply may be locked into long-term custody or in funds where redemptions are slow. If those coins aren’t available for quick sale, a large incoming sell order can push prices much further than expected.

Price discovery. A market where a few players control supply makes it easier for those players to move prices — intentionally or not. If big holders trade unevenly or execute large block trades over OTC desks, the public order book may lag behind true buying or selling pressure.

Volatility. Concentration raises the odds of sudden swings. If one major custodian shifts policy, if a government decides to liquidate seized coins, or if an institution rebalances a treasury, the market can see outsized moves. That doesn’t mean constant chaos, but it raises tail risk — the chance of rare, large moves.

On-chain metrics. When big pools dominate, some common on-chain indicators — like exchange balances or the share of supply active in the past year — need extra context. A drop in exchange reserves might look bullish, but if it represents transfer to long-term custody rather than retail demand, the market interpretation changes.

How we got here: accumulation over recent years

Concentration didn’t happen overnight. The trend accelerated after the 2020–2021 institutional wave, when corporate treasuries and large funds began adding Bitcoin. The 2021–2022 period saw exchanges expand custody to support a growing user base and new financial products. The arrival of regulated spot ETFs and larger custody solutions in 2023–2024 further pushed many coins into institutional custody.

Governments also added to concentration via seizures and retained holdings from high-profile law enforcement cases. And the behavior of long-term holders — wallets that rarely move coins — has amplified the picture by removing supply from day-to-day circulation.

Investor takeaways: how to think about risk, sizing and positioning

This mix is a double-edged sword for investors. On the positive side, concentration shows growing institutional adoption. Large, professional custodians and corporate treasuries signal that serious money sees Bitcoin as an asset class. That can build a firmer base under prices over the long run.

On the downside, concentration raises systemic risk. When a smaller set of holders controls supply, the chance of a single event causing a big price swing grows. That makes short-term timing trickier and increases the importance of managing position size and horizon.

For investors who are crypto-focused, a practical stance is to be explicit about exposure and scenario planning. Treat Bitcoin positions as potentially subject to sudden liquidity shocks. Keep sizing conservative enough that a large, sudden move doesn’t force unwanted selling. Consider hedging or using staggered entry and exit plans rather than all-or-nothing trades.

Also watch flows and on-chain signs: net flows into exchanges, changes in custodial balances, and large transfers between wallets. These are the early clues that concentrated holders are moving coins in ways that could affect price quickly.

How to read Glassnode’s data and what it misses

Glassnode classifies addresses using heuristics: patterns of movement, known exchange wallet structures, labels from public sources, and other on-chain behavior. That method is powerful but imperfect.

Some big addresses may represent many users pooled together. Others could be multi-party cold wallets that are hard to interpret. OTC trades, custody migrations, and wrapped or layer-two activity can obscure true ownership. And labels can be out of date as institutions redistribute holdings.

So treat the nearly one-third headline as a directional flag — a clear sign of concentration — rather than a precise, immutable fact about who controls what at every moment.

Bottom line: growing concentration of Bitcoin in the hands of a few is a structural shift. It underlines expanding institutional involvement, but it also raises short-term liquidity and volatility risks. For investors, the sensible response is clear-eyed sizing and closer monitoring of custody and exchange flows — not blind optimism or panic.
