The decision to lower the interest rate by the Federal Reserve stimulates the American economy, revives investment, and strengthens the US dollar. It also contributes to controlling inflation, but negatively impacts digital currencies and causes investments to focus on industry and technology. It encourages borrowing, which is why Jerome Powell's decision, the chairman of the Federal Reserve, had an effect on the current selling wave of Bitcoin and digital assets, leading to a decrease in their prices. However, there is a subsequent positive effect that contributes to an upcoming rally, encouraging investors to take loans from banks and invest in digital currencies to achieve significant profits. Both outcomes carry both negative and positive implications for the future of digital currencies. In other words, the Federal Reserve remains the ultimate decision-maker in all outcomes through the decisions made.
