Bitcoin recorded the largest weekly dollar gain in its history last week, rising $14,775 between Aug. 17 and Aug. 23, according to data from Galaxy Research. Over the same seven days, the cryptocurrency climbed 23.5% — its biggest weekly percentage gain since March 2023.

Record Weekly Dollar Gain

Bitcoin posted its largest weekly dollar gain on record during the week of Aug. 17 to Aug. 23, according to Galaxy Research, the research arm of digital asset financial services firm Galaxy Digital. The cryptocurrency climbed from $62,818 to $77,593, delivering a $14,775 weekly increase — the biggest dollar gain in Bitcoin's history.

The sharp rally reflects renewed buying interest, as institutional demand and positive market sentiment continued to support higher prices. The milestone highlights the scale of Bitcoin's latest advance compared with previous market cycles.

Strongest Percentage Gain Since March 2023

In percentage terms, Bitcoin gained 23.5% over the same period. According to Galaxy Research, the move ranks as Bitcoin's 41st-largest weekly percentage gain of all time, while also marking the strongest weekly percentage increase since March 2023 — a rally that coincided with the collapse of US regional lenders including Silicon Valley Bank and Signature Bank.

Dollar gains and percentage gains capture different dimensions of a price move: the former measures the absolute price increase over the week, while the latter expresses the move relative to the starting price. The gap between the two records is partly mechanical: as Bitcoin's price level has risen, any given percentage move translates into progressively larger dollar amounts, so dollar records can fall even when a rally ranks lower historically in percentage terms. Many of Bitcoin's largest weekly percentage gains date from its early years, when the asset traded at a small fraction of current prices.

Although the percentage gain was not a record, it underscores the strength of the latest rally after months of relatively subdued price action and reflects a notable improvement in market momentum.

Momentum Draws Investor Attention

The latest weekly gain reinforces growing optimism across the cryptocurrency market. Record dollar gains and the strongest weekly percentage advance in more than three years suggest renewed investor confidence. Even so, the week's closing level of $77,593 sits well below the $100,000 milestone Bitcoin first crossed in December 2024, meaning the record dollar gain occurred below the asset's previous peak rather than at fresh record prices. Market participants will continue monitoring institutional inflows, spot demand, and macroeconomic developments to determine whether Bitcoin can sustain its upward momentum in the weeks ahead.
