Key Takeaways
How much did crypto markets lose and how quickly?
The total crypto market capitalization plunged from $3.55 trillion to $3.32 trillion in the last 24 hours..
What does an Altcoin Season Index of 23 mean?
A reading of 23 indicates “Bitcoin Season,” meaning altcoins are severely underperforming Bitcoin. This is the lowest reading since March 2025.
The cryptocurrency market suffered a brutal $230 billion wipeout on 4 November, erasing gains from the previous 24 hours.
Ethereum led the decline as altcoins crashed harder than Bitcoin, pushing key sentiment indicators into panic territory and confirming the end of any remaining altcoin momentum.
$230 billion vanishes in hours
Markets started the day at $3.55 trillion, and as of this writing, total market capitalization had collapsed to $3.32 trillion. This was a 6.5% drop that accelerated throughout the trading day.

The chart shows a sharp cliff dive with no meaningful support holding.
Bitcoin fell 5.3% to around $100,900, breaking below the psychological $101,000 level for the first time in months.
However, Ethereum crashed harder, leading to a devastating selloff among major altcoins that exposed just how fragile the recent rally had become.
Ethereum leads Altcoin massacre
Ethereum crashed 12.15% to $3,166, dramatically underperforming Bitcoin’s 5.3% decline. The second-largest cryptocurrency suffered its worst single-day drop in months, falling from around $3,600 to test $3,000 support levels.
Technical analysis reveals a brutal breakdown of market structure. The LuxAlgo Market Structure indicator shows Ethereum broke through a critical “Break of Structure” (BOS) level around $3,600, triggering a cascade of selling that accelerated into the close.

Key support now sits around $3,000-$3,100. A break below this zone would likely trigger another leg down toward $2,800. Resistance reformed at $3,400-$3,600, with any recovery facing strong supply from underwater holders.
Altcoin season ends
While Bitcoin remained relatively resilient around the six-figure mark, Ethereum and the broader altcoin market bled significantly harder.
The divergence became crystal clear in the Altcoin Season Index, which plummeted to 23, its lowest reading since March 2025.

The index measures the performance of altcoins relative to Bitcoin. Readings below 25 indicate “Bitcoin Season,” meaning capital is rotating away from altcoins and into Bitcoin or fleeing crypto entirely.
At 23, the current reading shows altcoins are getting absolutely crushed.
The altcoin market capitalization has collapsed from approximately $1.8 trillion in September to around $1.4 trillion today, representing a $400 billion decline in just two months. The 90-day chart shows a brutal downtrend with no signs of reversal.
Fear takes over
The Crypto Fear and Greed Index crashed to 27, firmly in “Fear” territory. Just weeks ago, the index traded in the 60s-80s range, indicating greed and extreme greed. The rapid shift in sentiment from optimism to panic occurred in less than a month.
Trading volume reached $247 billion, indicating elevated levels that suggest active selling rather than passive holding.
When volume spikes during declines, it typically signals capitulation or forced liquidation rather than healthy profit-taking.
What this means for traders
The Altcoin Season Index at 23 means the altcoin season is over. Until the index recovers above 50, betting on altcoin outperformance remains extremely risky.
With fear gripping markets, sentiment needs significant repair before capital returns to speculative assets. For now, Ethereum and altcoins remain under severe pressure with no clear bottom in sight.
