$BTC Regulatory and economic policies significantly impacted the price of Bitcoin at key moments. For example, in 2017, the ban on exchanges in China caused abrupt drops, while institutional adoption in 2020 boosted its value. The approval of ETFs in the U.S. and fiscal stimulus policies in 2021 increased demand, raising the price. However, regulatory restrictions and announcements of bans in various countries generated volatility. In summary, regulatory decisions and economic policies shaped BTC's behavior, creating ups and downs in its value based on the perception of its acceptance and global regulation.
