Are the Biggest Holders Buying or Selling?

The biggest wallets sometimes move before the rest of the market — here's what they're doing.

THE READ
MIXED
The biggest holders are sending mixed signals.
27.9%of all Bitcoin held by the biggest wallets
Balances are down about 7K BTC over the past month — but the move is split: the very biggest added while other large wallets let go.
WHERE THIS SITS
Big holders letting goBig holders adding

Near a six-month low — big-holder balances haven't been this low in months.

This is a noisier read than most. Some of these wallets are exchanges, ETFs, and custody addresses, so a balance change isn't always a real buy or sell.
What changed this month
  • Big holders let go of about 6.8K BTC over the past month.
  • About 7 wallets dropped below the big-holder threshold this month.
  • The very biggest and the other large wallets are moving in opposite directions.

The very biggest vs the rest

Mostly large exchanges, ETF custodians, and a few of the wealthiest treasuries.

Top tier is mostly exchanges and ETFs — possibly absorbing what other holders release rather than fresh accumulation.

What this means

The very biggest are adding while other large wallets are letting go. Could reflect ETFs and exchanges absorbing supply other holders are releasing.

What would change this read?

If big holders flip to net buying across timeframes, that's historically preceded rallies.

Watch the very-biggest vs other-large split — if they diverge (one buying, one letting go), the signal gets murkier.

Sustained selling that accelerates is more cautionary than a single month of outflows.

Understanding Whale Flow

What we mean by big holders. This page tracks addresses holding at least 0.01% of all Bitcoin — roughly 1,990 BTC each, or hundreds of millions of dollars per wallet at today's price. There are around 800 of these wallets globally. They include major exchange cold wallets, spot Bitcoin ETF custodians, large treasuries, sizable funds, and the wealthiest individual holders. The page also tracks the very top tier separately — wallets with at least 0.1% of supply (about 19,900 BTC), which is dominated by exchanges and ETFs. These are often called 'whales' in crypto — but you don't need the slang to read the page.

What 'flow' means. We measure how much Bitcoin this group holds today versus 7, 30, and 90 days ago. When the total goes up, more Bitcoin is sitting in big-holder wallets — they're adding. When it goes down, less is sitting there — they're letting go. The actual buying or selling happens through exchanges, OTC desks, and other venues we can't see directly, but the resulting on-chain balance changes reveal the direction.

Why this might be a leading indicator. Large holders often have longer time horizons, better information, or simply more conviction than retail traders. Historically, sustained adding by this group has often preceded price rallies, and sustained selling has often preceded corrections. The signal isn't perfect — exchanges and ETFs muddy the picture, on-chain flows lag actual decisions, and big holders can be wrong too. But the direction is informative more often than not.
