I just reviewed the Bitcoin ETF flow data and something interesting is happening. The spot ETFs in the U.S. have just completed eight consecutive days of inflows totaling $2.1 billion. This is the longest streak since October 2025, when it drove Bitcoin to its all-time high of $126,000. The total assets in these ETFs are now around $102 billion, representing 6.5% of Bitcoin's market value.

The price movement has been quite clean: Bitcoin went from $68,000 to $77,000 during this period, almost perfectly synchronized with those inflows. But here’s what no one clearly mentions: while someone is buying $2.1 billion through ETFs, someone else is quietly selling.

On-chain data shows that Bitcoin has recovered its True Market Value at $78,100, the first level since mid-January. But the real problem is the next level at $80,100, which is the average cost basis for all those who bought in the last 155 days. Once Bitcoin breaks that level, more than 54% of recent buyers would be in profit. And this is where historically they start to sell.

Realized gains for short-term holders have already shot up to $4.4 million per hour. That’s three times the threshold that has preceded each local top this year. The setup is clear: either Bitcoin sustains the rally above $80,100 or it sells off again like every previous peak in this cycle. That’s the level worth watching.
