Bitcoin's social sentiment shifted from extreme fear to 'ultra FOMO' in just 72 hours, with prices nearing $80,000. Analysts warn that this enthusiasm could signal caution rather than optimism.

Bitcoin’s social mood swung from one extreme to the other in roughly 72 hours this week, with on-chain analytics firm Santiment tracking a shift from deep fear to what it’s calling “ultra FOMO mode” between Monday and Thursday.
The firm is now reading that crowd enthusiasm as a warning, not a green light.
Monday looked rough. Bitcoin had just stalled near $76,000, negative commentary piled onto social platforms, and Santiment’s positive-negative sentiment ratio dropped hard into FUD territory. The firm flagged that as a buy signal.
By Thursday, April 23, Bitcoin had recovered above $78,000 and was knocking on $80,000 again. As of writing, BTC is trading around $77,500, up by about 4% on the week and almost 10% over the past month per CoinGecko, though it’s still around 38% off the all-time high above $126,000 set in October 2025.
Santiment posted earlier today that the ratio had flipped hard into “ultra FOMO mode” and called it a “clear caution signal,” adding that a sustained break above $80,000 would be more convincing if optimism pulled back slightly first.
“Prices can continue to rally, and a breach above this resistance level would be massive in bringing in new and returning traders,” the firm wrote. “However, it will ideally happen when optimism calms down just slightly.”
ETF flows were more straightforward, with Farside Investors logging $223 million in net inflows across US spot Bitcoin ETFs on April 23, where BlackRock’s IBIT accounted for $167.5 million of that. Wise Crypto noted IBIT has pulled in roughly $3 billion year-to-date, landing in the top 1% of all ETFs by inflows.
Not all analysts agree BTC’s recent move was fully supported by strong demand. According to one of them, Carmelo Alemán, the rally from about $76,000 to $79,400 was largely by futures activity rather than spot buying.

'Ultra FOMO mode' refers to a heightened state of enthusiasm among investors, which Santiment warns could indicate potential market caution.

During that move, open interest went up from about $24.9 billion to $28 billion, while at the same time, short liquidations across Bitcoin and Ethereum were over $1.1 billion. This, per the market watcher, meant that a lot of leveraged bearish positions had to close, and that’s what drove prices up.
While such rallies can be sharp, they can also be unstable if they’re not backed by sustained spot demand, and Alemán noted that this structure often leaves the market vulnerable to reversals if buying pressure fades.
