Bitcoin in ‘high-risk zone’ as ETF outflows signal institutional exit: Swissblock
Swissblock says Bitcoin has entered a high-risk zone as spot ETF outflows and institutional selling outweigh demand.
Intelligence analysis by GPT-5.4 Mini

Swissblock says Bitcoin’s risk score has climbed to 33/100 as May shifted from accumulation to distribution. The firm and Glassnode both point to persistent US spot ETF outflows as a sign that institutional demand is weakening.
Bitcoin is like a big ball being passed around by many hands. Right now, some of the biggest hands are letting go more than they are catching it, so the ball is wobbling.
A company that watches Bitcoin says the market is in a risky spot because more money is leaving Bitcoin funds than coming in. That can make prices harder to hold up.
News about strikes in Iran also made traders nervous, and Bitcoin dipped a little. But it has been stuck in a wide price range for months, so this move is part of a bigger shaky pattern.
Analysis
Risk index turns higher
Swissblock says Bitcoin is sliding into a high-risk environment because selling pressure is now dominating buying pressure. Its proprietary risk index is at 33 out of 100, and the firm says that when the index shows selling pressure overwhelming the market, it reflects institutional distribution rather than casual profit-taking.
ETF demand is weakening
The article says May has shifted from accumulation in March and April back into distribution. Swissblock argues that spot Bitcoin ETF demand is no longer absorbing selling pressure effectively, and warns that without stronger ETF support, the risk index could keep rising.
Glassnode added that US Bitcoin ETFs have seen net outflows on nearly every trading day since May 7. It described that as a persistent institutional sell signal lasting more than two weeks, with the steady outflow adding supply “without a visible demand offset.” CoinEx chief analyst Jeff Ko told Cointelegraph that more than $2 billion has left spot ETFs over the past two weeks, showing institutional risk appetite remains cautious.
Geopolitics add pressure
The market weakness was intensified by reports that the US launched fresh strikes on Iran. Bitcoin fell about 1% on Tuesday morning, dropping from above $77,000 to just below $76,500 on Coinbase. Even so, the article notes Bitcoin has been range-bound for almost four months, and Ko suggested the short-term reaction could still lean risk-on if investors focus on a possible US-Iran peace deal rather than the strikes themselves.
