Bitcoin holders realized $336.6M in profit on September 10.

But it wasn’t evenly distributed across the holder base.
One cohort dominated:
• 100–1,000 $BTC : $128.2M
• 1,000–10,000 $BTC: $56.6M
• Total realized profit: $336.6M
The 100–1,000 $BTC cohort alone generated roughly 38% of the entire day’s realized profit.
Combine both whale cohorts and that rises to around 55%.
There’s another useful comparison.
The aggregate realized price of 100–1,000 $BTC wallets is roughly $67.2K, versus $52.2K network-wide.
So this cohort has a significantly higher cost basis than the average $BTC holder, while still sitting on substantial embedded gains at current prices.
That helps explain why relatively modest coin movement can generate such a large share of realized profit.
One important caveat:
realized profit does not automatically mean selling.
Coins can move to exchanges, OTC desks, collateral accounts, custodians or simply another wallet controlled by the same entity.
So the chart doesn’t prove whales are dumping.
It shows something more specific:
Bitcoin’s current profit realization is heavily concentrated among larger holders, with the 100–1,000 $BTC cohort responsible for nearly $2 of every $5 realized on September 10.
That’s the chart.
