Bitcoin’s Retreat Reached a 20-Day Low Near $43,000

Bitcoin’s retreat deepened on February 28, 2021, when Reuters recorded the dollar price at $43,165.78, down 6.39% from the news service’s stated previous close. The reading put bitcoin 26% below Reuters’ February 21 high of $58,354.14 and at its lowest level in 20 days.

That reversal was the day’s clearest cryptocurrency development. It interrupted a February surge associated with growing corporate and financial-industry interest, and it showed that institutional-adoption headlines had not removed bitcoin’s capacity for abrupt, market-wide repricing.

A point-in-time reading, not an official close

Reuters’ February 28 update said bitcoin had lost $2,944.20 from its previous close by the time of the $43,165.78 observation. In the same update, Reuters put ether at $1,329.46, down 8.88%, or $129.57, on the same comparison basis. CoinDesk separately reported bitcoin trading near $43,000 and described the level as the lowest in about three weeks.

Those figures are verified as contemporaneous published observations, but their precision has limits. Bitcoin and ether trade continuously on multiple venues; neither asset has a universal closing auction or a consolidated tape. Reuters did not identify the underlying exchange, composite, cutoff time or timezone for its “previous close” calculation in the surviving syndicated copy. The 6.39% and 8.88% changes should therefore be read as Reuters’ snapshot-to-reference comparisons, not Coinburn calculations or globally binding daily returns.

The defensible market claim is correspondingly narrow: by February 28, bitcoin had fallen into the low-$43,000 area and ether had also declined sharply. The cited records do not establish the eventual UTC close, total global volume, liquidation value or performance on every exchange.

Corporate adoption met market risk

The pullback mattered because it arrived after two prominent corporate treasury disclosures. Tesla’s February 8 annual report said the company had invested an aggregate $1.50 billion in bitcoin after revising its investment policy in January 2021. The filing also warned that digital-asset prices could remain highly volatile and described unique risks of loss.

Square added another event-day-known reference point. On February 23, the payments company announced that it had purchased approximately 3,318 bitcoin for an aggregate $170 million. These records documented real corporate balance-sheet demand; they did not promise price stability or establish a valuation floor.

By February 28, the gap between the adoption narrative and the trading outcome was visible. A 26% retracement from the February 21 peak had unfolded in seven calendar days. That percentage is Reuters’ comparison, not an independently reconstructed exchange return.

Context without a single-cause claim

A February 26 Reuters report connected bitcoin’s broader weekly retreat with a selloff in risk assets as global bond yields rose. That was a plausible contemporaneous macro explanation, especially because equities and other high-valuation assets were also under pressure. It was not proof of exclusive causation.

The surviving sources do not separate the effects of profit-taking, leverage, derivatives liquidations, venue-specific liquidity, corporate news or macro positioning. Nor do they establish that one identifiable order or announcement triggered the February 28 low. Any stronger causal account would require timestamped venue trades, order-book data and derivatives records that are not present here.

The February 28 record therefore marks a stress test rather than a verdict on adoption: bitcoin reached a 20-day low near $43,000, ether weakened alongside it, and recently disclosed corporate purchases coexisted with a rapid correction. Whether that decline would persist was unknowable from the evidence available on February 28, 2021.
