Bitcoin's recent volatility between $100K and $110K is largely driven by U.S. tariff policies and trade negotiations. With the U.S. imposing 25% tariffs on Japan and Korea, $BTC briefly dipped below $108K. However, the extension of the trade deal deadline to August 1 has given $BTC a boost, approaching $110K. Traders should keep an eye on geopolitical developments as they continue to impact BTC's price action.
