Bitcoin’s Thanksgiving selloff exposed leverage and exchange strain

Bitcoin plunged on November 26, 2020, interrupting a seven-week advance just as the cryptocurrency approached its December 2017 record. Reuters observed bitcoin falling as much as 13% to $16,317 before recovering part of the loss. The news service reported that bitcoin was last down 8% when its account was updated at 10:30 UTC.

Those figures describe an intraday market snapshot, not a standardized UTC-day return or a closing price from one named exchange. Coinbase’s own November 28 market review characterized the broader move as an 11% decline to $17,100. The difference illustrates an important limitation of cryptocurrency price reporting in 2020: bitcoin traded continuously across independent venues, so lows and percentage changes varied with the market, currency pair, timestamp and comparison point.

Even with that qualification, the direction and scale of the reversal were clear. Bitcoin had reached $19,521 on November 25 in the Reuters measurement, close to the record associated with the 2017 boom. The November 26 retreat therefore became the first severe test of a rally increasingly attributed to institutional participation rather than the retail speculation that defined the previous cycle.

Leverage met a thinner holiday market

Reuters reported that traders cited the unwinding of highly leveraged positions after bitcoin’s rapid approach toward its record. That explanation was an attributable contemporaneous assessment, not a verified calculation of liquidations. No comprehensive, regulator-supervised dataset covered every crypto derivatives venue, and the surviving sources do not establish a single trigger.

Coinbase’s subsequent review supplied evidence that the session was nevertheless unusually active. The company said institutional-client volume exceeded $2.4 billion on each day from November 23 through November 26, placing all four sessions among its ten largest institutional-volume days at that point. Coinbase also said its over-the-counter desk remained busy on November 26, with some clients increasing positions during the decline and crypto-native firms rotating from smaller tokens into bitcoin and ether.

That activity complicates a simple flight-from-bitcoin narrative. The selloff demonstrated that new institutional demand had not eliminated volatility, but Coinbase’s account suggested that at least some large clients treated lower prices as an opportunity to add exposure. Because these observations came from Coinbase, they described that company’s clients and could not establish behavior across the entire market.

Exchange infrastructure came under pressure

Market access also became part of the story. Coinbase Support said it was investigating connectivity issues affecting Coinbase and Coinbase Pro on November 26. A contemporaneous CoinDesk report placed bitcoin down 11.54% at approximately $17,120 while the incident was unfolding. The outage did not prove that Coinbase caused the broader decline, but it showed how centralized access points could become unreliable during the periods when customers most wanted to trade.

A separate exchange event added potential selling pressure. OKEx restored withdrawals for all digital assets at 08:00 UTC on November 26 after suspending them on October 16 because a private-key holder had become unreachable. OKEx said users could withdraw without restrictions. Coinbase later identified that reopening as one possible contributor to the decline, reasoning that customers gaining access to previously immobilized assets could increase available supply. That was Coinbase’s interpretation, not proof of causation, and the surviving primary notice does not quantify net selling.

What the session established

The verified record supports a narrower conclusion than any single-cause explanation. On November 26, bitcoin experienced a double-digit intraday reversal near its former record, leverage was cited by market participants, one major U.S. exchange reported connectivity problems, and another large exchange restored withdrawals after five weeks. Together, those developments exposed the operational and liquidity risks still surrounding bitcoin’s increasingly institutional market.
