I think people are focusing on the wrong part of Bitcoin’s latest ETF numbers.
It’s not just that $1.01B flowed into U.S. spot Bitcoin ETFs over three trading days.
It’s who had to sell the BTC on the other side.
On September 3 alone, ETF inflows reached $730.8M.
At around $78K–$79K per BTC, that’s roughly 13,000 BTC worth of demand.
And here’s where it gets interesting.
Bitcoin’s long-term holder supply has climbed to around 16.5M BTC.
That’s close to 79% of Bitcoin’s eventual 21M supply.
But I don’t think the takeaway should be:
“79% of BTC is locked, so supply is running out.”
That’s too simple.
Long-term holders can sell.
The number I’m watching is how quickly they distribute when new demand arrives.
Because if ETFs keep absorbing billions while long-term holders continue sitting on their coins, the market doesn’t need a huge supply shortage to move higher.
It only needs new demand to grow faster than willing sellers.
That’s the hidden part of this setup.
And there’s another side to it.
If BTC keeps pushing higher, those long-term holders suddenly have a much bigger incentive to take profits.
So I’m watching three things now:
• ETF flows — does the $1B burst continue?
• LTH distribution — are older holders actually selling into this demand?
• Price reaction — can BTC break through the $82.8K area without a major increase in sell-side pressure?
If ETF demand stays strong and LTH selling remains controlled, Bitcoin could become increasingly sensitive to relatively small changes in demand.
But if old holders start distributing aggressively, that “supply squeeze” narrative can disappear very quickly.
That’s why I’m watching the seller, not just the buyer.
