Bitcoin bullish sentiment hit its highest level of 2026 even as ETF outflows and market declines continued.
Bitcoin News
Bullish comments about Bitcoin (BTC) on social media outnumbered bearish ones by a ratio of 2.23 to one on May 31, the highest positive reading of the year, according to crypto analytics platform Santiment. The firm published the data on May 31, noting that the broader crypto market was declining at the same time.
Santiment flagged the gap between social sentiment and market conditions as a reason for caution. The two largest positive-sentiment spikes earlier in 2026 each preceded short-term price drops. Deeply negative sentiment readings, by contrast, have tended to align with local price bottoms.
ETF Outflows Contrast With Online Optimism
Spot Bitcoin exchange-traded funds (ETFs) recorded outflows for 10 consecutive trading days through May 30. Total net redemptions from those funds exceeded $2.97 billion since May 15, according to Santiment.
The Crypto Fear and Greed Index posted a score of 23 on May 31, placing it in Extreme Fear territory. MN Trading Capital founder Michaël van de Poppe said current market conditions represent the worst sentiment he has ever encountered in crypto. He said it surpasses the negativity of both the 2018 and 2022 bear markets.
Some traders treat extreme sentiment readings as contrarian signals. When BTC fell to a yearly low of $60,000 in February 2026, Gemini co-founder Tyler Winklevoss wrote on X that sentiment was poor enough to make him optimistic about where prices were headed.
Does Retail Sentiment Still Matter?
Santiment noted that extreme optimism in social commentary has historically preceded short-term price declines more consistently than continued gains. Market participants often watch sentiment data to gauge where other investors may be positioned, and to inform their own decisions about buying or selling.
Swan Bitcoin CEO Cory Klippsten argued that retail sentiment still carries meaningful weight, even as institutional interest in BTC has grown. "It still does. You have to remember it's not like BlackRock owns the Bitcoin and Fidelity owns the Bitcoin. It's a bunch of retail accounts, mostly, that actually buy that," he said.
