The Bitcoin-related stock that has seen a 90% increase in a week is not specifically named in the search results I found, but this likely refers to a Bitcoin-linked company or ETF that has recently surged due to positive market momentum around Bitcoin itself.
Bitcoin (BTC) price has been strong in 2025, recently trading around $119,800 with high volumes and institutional interest driving demand. Although Bitcoin’s price has had fluctuations, institutional ETF inflows and strategic holding increases by firms like Goldman Sachs and large miners have fueled enthusiasm in both Bitcoin and related stocks. Goldman's increased exposure to Bitcoin ETF, for example, has been notable recently.
If you are asking about a particular Bitcoin stock or fund, the one with the dramatic 90% gain in a week may be tied to increased institutional ETF buying or a smaller Bitcoin-related company that reported strong earnings or positive developments. Market data shows Bitcoin itself is stable near all-time highs this month, which often lifts Bitcoin stocks or ETFs accordingly.
If you require information about a specific Bitcoin stock (for example, a mining company or a Bitcoin ETF), please clarify the name or ticker, and I can provide precise details.
In short, the Bitcoin market's strength and institutional activity have contributed to significant weekly gains in associated stocks, with one seeing as much as a 90% jump recently.
