Bitcoin is holding near $80,000, yet crowd enthusiasm has rarely been lower — and software engineer Michael Sullivan argues that disconnect may be the most bullish signal in the market today.
Sullivan, author of Bitcoin Sentiment Weekly, examined language-based sentiment data in a new interview with Bitcoin Magazine. Where price charts record what the market did, language-based sentiment scores what participants are actually saying, tracking how much excitement, conviction and desire the crowd expresses. He explains that those measures have been washed out to levels he compares with 2015, a pattern he interprets as the early stages of a "disbelief rally" — a phrase for advances that begin while much of the market still doubts them.
His remarks follow Bitcoin's pullback from roughly $86,000. Sullivan draws parallels with sentiment conditions observed in 2015 and 2022 — two years remembered in Bitcoin's history for extended drawdowns — and describes how to tell when the Bitcoin market becomes overheated. The framing echoes the market adage behind the interview's title: prices are said to climb a "wall of worry" when they advance despite widespread skepticism among participants.
The conversation also widens beyond sentiment itself: Sullivan discusses Bitcoin and AI as a candidate narrative for the next bull run, examines how AI-driven deflation fits his case for Bitcoin, and addresses the frustration currently showing among short-term holders.
