Bitcoin briefly dropped below $83,000 late Monday as thin liquidity and growing concerns over a potential index methodology change combined to accelerate selling pressure. The decline pushed other major cryptocurrencies lower, with XRP, Ether and Solana posting losses of up to 2% during early Asian trading hours Tuesday.
What Happened: Price Drop
Bitcoin briefly fell below $83,000 late Monday before recovering to trade above $86,000 during Asian hours Tuesday morning. Cardano's ADA and BNB Chain's BNB also declined, while Ether traded at $2,803.60.
The drop followed thin weekend trading and concerns over MSCI's proposal to exclude companies with heavy cryptocurrency holdings from its major equity indices.
The move would affect firms collectively holding more than $137 billion in digital assets, including Strategy Inc., Marathon, Riot, Metaplanet and American Bitcoin, which together represent roughly 5% of all Bitcoin in circulation.
Market participants attributed the decline to structural weakness rather than macroeconomic triggers. The selling came amid shallow order books and limited market depth, conditions that intensified pressure across digital asset markets.

Why It Matters: Index Exclusion
Farzam Ehsani, CEO of crypto exchange VALR, said the decline reflects underlying fragility in market structure. "Bitcoin's drop below $90,000 is the result of a collision between the fragile market structure and weak liquidity conditions observed over the weekend," Ehsani said. He added that pressure intensified because order books lacked sufficient depth to withstand the liquidity shock.
Traders have begun pricing in potential forced selling from index funds if MSCI reclassifies affected companies.
"Any rule change automatically triggers a review of their holdings, potentially leading to forced sell-offs of these companies' shares and triggering significant capital flows," Ehsani said.
He warned that investors should prepare for short-term imbalances from forced capital flows.
The December decline capped a difficult November for Bitcoin, which finished down 17.5% in one of its steepest monthly drops in three years. A sustained break below roughly $80,500 would open the path toward a $64,000 technical level tracked by some traders. Ehsani said Bitcoin could test the $60,000 to $65,000 range if selling continues, levels where institutional buyers might emerge.
Despite broader market weakness, U.S.-listed cryptocurrency exchange-traded funds showed selective demand. Solana funds recorded five consecutive weeks of net inflows, adding more than $600 million since late October. Spot XRP ETFs surpassed $666 million in cumulative inflows.
