Bitcoin Ended a Volatile Week Near $56,000

Bitcoin ended March 28, 2021 near $56,000 after recovering sharply from a midweek selloff that had taken Coinbase’s BTC-USD market close to $50,000. The rebound removed the immediate threat of a deeper breakdown, but it did not erase the week’s decline or prove that derivatives settlement caused the reversal.

Coinbase’s BTC-USD candle for the UTC day closed at $55,778.82. CoinMarketCap’s separate historical snapshot placed bitcoin at $55,950.75, down 0.04% over its displayed 24-hour window and 2.73% over seven days. The difference reflects distinct markets, aggregation methods and observation conventions; bitcoin has no consolidated global closing auction.

The development mattered because it followed a week in which traders had focused heavily on a record-sized bitcoin options expiry. By March 28, spot prices had stabilized well above the week’s low without producing the disorderly post-expiry move some market participants had feared.

A sharp recovery inside a losing week

On Coinbase, the measured week began at $57,377.29 at 00:00 UTC on March 22. BTC-USD reached a weekly high of $58,421.68 during that session before falling to $50,305 on March 25. That high-to-low move was a 13.89% drawdown, calculated by Coinburn from the venue’s candles.

Bitcoin subsequently recovered to the March 28 close of $55,778.82, a 10.88% increase from the March 25 intraday low. Even after that rebound, the Coinbase instrument remained 2.79% below its March 22 opening price.

The March 28 session itself was subdued. BTC-USD opened at $55,856.54, traded between $54,701 and $56,587.08, and closed 0.14% lower. The $1,886.08 range equaled 3.45% of the session low. Coinbase reported volume of 9,235.8030 BTC, approximately 68.84% below the 29,642.0442 BTC recorded during the March 25 UTC candle.

Those volume figures apply only to Coinbase’s BTC-USD order book. They do not measure global bitcoin turnover, dollar-equivalent derivatives volume or unique buyers and sellers.

The options-expiry question

CoinDesk reported on March 25 that more than $6 billion in bitcoin options were scheduled to expire on March 26 across the market, describing it as a record expiration. Traders and analysts debated whether options positioning had contributed to the preceding decline or could intensify volatility around settlement.

Contemporaneous coverage on March 28 described bitcoin as consolidating above $55,000 after the expiry passed without the feared collapse. That chronology is verifiable. A causal conclusion is not.

An options expiry changes the outstanding derivatives positions and hedging requirements of affected traders. Spot bitcoin also responds to liquidity, leverage, macroeconomic conditions, exchange-specific order flow and changing expectations. Daily candles cannot identify which factor drove a particular trade, and the surviving records do not establish that expiration mechanically produced the weekend recovery.

What the market record established

CoinMarketCap’s March 28 snapshot estimated bitcoin’s market capitalization at $1.044 trillion using a reported circulating supply of 18,667,250 BTC. It listed rolling 24-hour volume of $47.69 billion. Market capitalization was a price-times-supply estimate, not the amount of cash invested in bitcoin or a measure of immediately available liquidity.

The same snapshot placed ether at $1,691.36, down 1.46% over 24 hours and 5.42% over seven days. That broader weakness supports the interpretation that the week’s pressure was not confined to one bitcoin trading venue.

The defensible March 28 conclusion is narrow: bitcoin recovered most of its late-week Coinbase decline and finished near $56,000, while trading on that venue was comparatively quiet. The recovery demonstrated resilience after a heavily watched derivatives event, but it did not settle whether the correction had ended, identify the buyers or establish a reliable relationship between options expiration and future prices.
