The drop follows a bruising November in which Bitcoin shed more than $18,000, marking its largest dollar loss since May 2021 — a period remembered for a cascade of crashes across the crypto ecosystem. Analysts say the latest slide underscores Bitcoin’s growing sensitivity to broader market sentiment, particularly as uncertainty clouds the outlook for year-end trading.
Seasonality and Sentiment
Although Bitcoin’s relatively short trading history offers limited seasonal guidance, past data shows the cryptocurrency typically gains in December — an average increase of 9.7%. October has historically been its strongest month, while September tends to be the weakest.
But analysts caution that Bitcoin’s traditional seasonal patterns may matter less this year, given its unusually tight correlation with the stock market.
“Bitcoin tends to be a leading indicator for overall risk sentiment right now, and its slide does not bode well for stocks at the start of this month,” said Kathleen Brooks, research director at XTB. She added that the recent sharp drop in volatility — with the VIX falling below its 12-month average — may have unsettled investors already wary of economic uncertainty.
Futures markets are also signalling caution. CME Bitcoin futures expiring three months from now are trading at their smallest premium to near-dated contracts in at least a year, reflecting diminishing confidence in a sustained price rebound.
Ether, the second-largest cryptocurrency, mirrored the decline, sliding nearly 6% to $2,845. Ether dropped 22% in November — its worst month since a 32% loss in February.
Mounting Pressures Across the Crypto Landscape
A cluster of negative developments added further strain to the crypto market on Monday, according to Jefferies strategist Mohit Kumar.
Last week, S&P Global downgraded Tether’s rating, citing an uptick in higher-risk assets within its reserves and persistent disclosure gaps — a claim the stablecoin issuer strongly rejected. At the same time, Strategy, the world’s largest corporate holder of Bitcoin, signalled it may sell part of its holdings if its internal “mNAV” ratio — enterprise value relative to the value of its Bitcoin holdings — drops below 1. The metric currently sits near 1.19.
Shares of Strategy and other crypto-exposed firms, including Coinbase, Riot Platforms, and MARA Holdings, slipped 3–4% in premarket trading. Strategy’s stock, down 60% over the past year compared with Bitcoin’s 13% decline, is already at risk of being removed from key benchmark indices — a move that could intensify pressure on both its share price and the mNAV metric. MSCI is expected to conclude a consultation this month on whether companies with digital assets exceeding 50% of their balance sheets should be excluded from major indices.
With investors pulling back across the sector, the total crypto market has shrunk dramatically. After peaking at around $4.3 trillion, the market has shed more than $1 trillion in value, according to CoinGecko.
Bitcoin’s latest slump adds to growing uncertainty over whether cryptocurrencies can regain momentum before the year closes, as sentiment remains fragile and traditional markets brace for a turbulent December.
