The continuous rally of Bitcoin above $90,000 is mainly influenced by macro - economic factors. Loose monetary policies globally, with central banks maintaining low - interest - rate environments and large - scale quantitative easing, have increased the money supply. This makes Bitcoin, with its fixed supply of 21 million coins, an attractive hedge against inflation. Also, geopolitical tensions and uncertainties in traditional financial markets drive investors to seek alternative assets like Bitcoin, which is not directly tied to any country's economic fundamentals.
