Bitcoin Ends August Lower as the Market’s Recovery Loses Momentum

Bitcoin ended August 2019 with a monthly loss, interrupting the force of a recovery that had carried the asset far above its levels at the beginning of the year. CoinMarketCap’s historical snapshot for August 31 records bitcoin at $9,630.66, with a market capitalization of $172.47 billion and a reported circulating supply of 17,908,500 BTC.

Using the opening price of $10,077.44 on August 1 and the August 31 value of $9,630.66 from the same daily market series, the calculated decline was approximately 4.4%. The calculation is `(9,630.66 ÷ 10,077.44 − 1) × 100`, rounded to one decimal place. Because cryptocurrency trades continuously across venues, this is a dataset-specific monthly result rather than a universal closing price.

A third negative month

The August decline was bitcoin’s third negative calendar month of 2019. Contemporaneous CoinDesk reporting on August 30 identified January and July as the other losing months and described bitcoin as approximately 4.8% below Bitstamp’s August 1 opening price of $10,096 at the time of its report.

That 4.8% figure and the 4.4% reconstruction are not directly interchangeable. The CoinDesk measurement used Bitstamp prices before the final August 31 UTC close, while the reconstruction uses a separate historical daily series and its own aggregation methodology. The defensible conclusion is therefore that bitcoin lost roughly 4% to 5% during August, not that every exchange produced an identical return.

The final day itself was comparatively quiet. CoinMarketCap’s snapshot placed bitcoin’s 24-hour change at 0.19% and its seven-day change at negative 4.76%. Reported 24-hour volume was $11.45 billion, but that aggregate should be treated cautiously: exchange-reported cryptocurrency volume in 2019 was not uniformly audited, and different data providers applied different venue-selection and screening rules.

Broader market figures showed that the weakness was not confined to bitcoin. In the same August 31 snapshot, Ether was priced at $172.47 and had fallen 9.18% over seven days. XRP was $0.2592, down 4.39% over seven days, while bitcoin cash was $279.94, down 8.69%. These are snapshot returns from CoinMarketCap’s measurement window, not synchronized executable prices from a single exchange.

Why the close mattered

Bitcoin’s inability to regain its monthly opening level mattered because it followed a volatile summer in which large price movements had returned to the market. The August result did not establish a durable trend by itself, but it showed that renewed interest in bitcoin had not eliminated substantial drawdowns or fragmented price discovery.

The institutional context was also changing. Regulated bitcoin futures were already trading at CME, giving professional participants a cash-settled instrument for gaining or hedging exposure. That market remained much smaller than reported global spot activity, but its existence provided a regulated reference point distinct from the numerous offshore exchanges included in broad market aggregates.

Later documentary context

A Bitwise presentation delivered to U.S. Securities and Exchange Commission staff on September 12, 2019 used data through August 31. It reported estimated August average daily notional volume of $234.39 million for CME bitcoin futures and compared that figure with approximately $1 billion in daily activity across ten spot exchanges Bitwise considered economically significant. Those figures were presented after the event date and reflect Bitwise’s methodology and advocacy in support of a proposed exchange-traded product; they clarify the institutional setting but were not part of the public record on August 31 itself.
