Internet reports that in March 2025, the search popularity of "Bitcoin" on Google was 34, the highest level so far in 2025. The search popularity in January and February was only 31 and 27 respectively. This marks a 26% month-on-month relative increase in "Bitcoin" search volume, and also marks a shift in the indicator's continued decline since November 2024. Similarly, the search popularity of "Ethereum" on Google in March also reached its highest level so far in 2025, recording 19. A slight increase from 16 last month. Analysts said that while still far from reaching previous cyclical highs, Google's rising search interest in Bitcoin and Ethereum in March may reflect a renewed interest in retail investors, at least better than the performance so far in 2025. A broader theory for rising interest in Bitcoin in March may be the newly announced tariffs in the United States, which may reignite the long-standing narrative of "digital gold" and "store of value" associated with Bitcoin, especially in the context of rising geopolitical or macroeconomic tensions. This theory is supported by the BTC to SPX ratio, which has increased by more than 8% since the Liberation Day tariff was announced on April 2.
