Bitcoin’s seven-day rebound reached 18.96% on March 4

Bitcoin reached $11,512.57 in CoinMarketCap’s historical snapshot dated March 4, 2018, completing a reported 18.96% seven-day advance. The move restored Bitcoin’s aggregate market value to $194.57 billion and marked a sharp rebound from the disruption that had defined the opening weeks of 2018.

The recovery was consequential because Bitcoin was not merely rising with the broader market. CoinMarketCap recorded Ether at $866.68, up 2.22% over its corresponding seven-day window, while XRP gained 7.09% and Bitcoin Cash advanced 9.49%. Among the four largest assets by reported capitalization, Bitcoin had the strongest weekly return.

The rebound in numbers

CoinMarketCap’s preceding weekly snapshot, dated February 25, placed Bitcoin at $9,664.73 with a market capitalization of $163.20 billion. Comparing the two displayed prices produces a 19.12% increase, close to—but not exactly the same as—the March 4 page’s reported rolling seven-day return of 18.96%.

That difference is a measurement warning, not evidence of an error. The two archived pages do not disclose an exact observation timestamp, while a rolling return can use endpoints that differ from the visible weekly snapshot values. Coinburn’s 19.12% calculation therefore describes the two displayed observations only; 18.96% is CoinMarketCap’s own seven-day field.

The March 4 snapshot also listed 16,900,387 BTC in circulation and $6.08 billion of reported 24-hour volume. Its calculated market capitalization rose 19.22% between the February 25 and March 4 snapshots. That increase slightly exceeded the price calculation because the reported circulating supply expanded between the observations.

These were aggregate market estimates, not executable prices from one exchange. The volume figure combined a rolling 24-hour window across venues and should not be interpreted as a calendar-day total or as audited turnover. An institutional series maintained by the Federal Reserve Bank of St. Louis and sourced to Coinbase uses a different convention: one Coinbase observation at 5 p.m. Pacific each day. Venue choice and cutoff time can consequently produce different daily prices without invalidating either dataset.

A recovery, not a return to the peak

The March 4 level remained far below the late-2017 high. CoinMarketCap’s December 17, 2017 snapshot recorded Bitcoin at $19,140.76. The March 4 observation was 39.85% lower by Coinburn’s calculation, illustrating how much of the earlier decline remained unrecovered despite the strong seven-day performance.

That distinction mattered institutionally. A nearly 19% weekly gain could signal renewed risk appetite, but it did not erase the volatility concerns being raised by policymakers. On March 2, Bank of England Governor Mark Carney argued that crypto-assets were failing to perform the conventional functions of money and called for the surrounding ecosystem to be held to standards comparable with other financial activities. He distinguished regulation from a prohibition on technological development.

A Reuters report carried on March 4 framed Carney’s intervention as part of a widening policy response addressing consumer protection, market integrity, money laundering and sanctions evasion. Those concerns were already knowable when the March 4 market snapshot was recorded; they are context, not a proven explanation for that day’s price.

What March 4 established

The defensible conclusion is narrow. Bitcoin had staged the strongest seven-day advance among the four largest crypto assets in CoinMarketCap’s March 4 snapshot and had returned above $11,500 on that dataset. It was still almost 40% below the December 17 snapshot level, and the surviving evidence does not establish what caused the rebound or whether it would persist.
