Trump's proposed tariffs can impact Bitcoin, Ethereum, and other major cryptocurrencies in multiple ways. Firstly, tariffs may heighten economic uncertainty. When investors are anxious about global economic growth due to tariffs, they might sell off risk - assets like cryptocurrencies, causing price drops. Secondly, if tariffs lead to inflation, some investors may view Bitcoin as a hedge, potentially driving its price up. For Ethereum, as a key platform for various decentralized applications, economic instability from tariffs could affect the development and adoption of these apps, influencing its price.
