ETF holders’ cost basis is 81,722. This level is crucial.
There’s a number I’ve been checking over and over these past two days: 81,722.
That’s the average cost basis for holders of U.S. spot BTC ETFs. BTC’s recent low was just above 80,400, which briefly pushed the entire ETF group into unrealized losses.
And you’ve seen what happened next: ETFs saw $729 million in outflows over two trading days.
But when you break it down, it gets interesting. The fund with the biggest outflows saw $408 million leave on its own—more than the net total. Meanwhile, the largest fund actually bucked the trend and took in over $330 million. In other words, institutions aren’t all running for the exits: some are selling, while others are buying.
This kind of divergence is common. The area around cost basis is always where bulls and bears clash most intensely. Those afraid of losses sell around breakeven, while those with a longer-term outlook see a discount.
Now BTC is back above 83,000, and ETFs as a whole are back in profit. That level has shifted from resistance to support.
Here’s how I’m thinking about it:
As long as BTC can hold above 81,722, ETF selling pressure should naturally ease, because most people don’t sell at a loss when they’re in profit.
If BTC falls decisively below it again and outflows continue for several days, that would suggest institutions have truly run out of patience. At that point, there could be more room to fall.
This isn’t some kind of mystical number. It’s the cost basis of hundreds of billions of dollars in real money—and that’s more convincing than any chart line. I’d recommend writing it down.
