The cryptocurrency market has indeed faced significant challenges recently, including BTC's price volatility and major bearish factors such as El Salvador revoking BTC's status as legal tender. Although these developments may seem like the end of the bull market, a definitive conclusion would be premature.

High market volatility does not necessarily signal a long-term reversal. Analysts like Yu Jianing have emphasized the need for risk management and a rational approach amidst macroeconomic uncertainty. Factors such as U.S. Federal Reserve policies and changing market expectations have contributed to the current bearish sentiment.

Despite these challenges, institutions like Standard Chartered Bank remain optimistic, predicting a significant rise in BTC prices over the next few years due to the growing maturity of BTC ETFs and reduced volatility. Companies like Strategy (formerly MicroStrategy) are continuing their strategic BTC investments, though with a more cautious approach.

The recent policy changes under the Trump administration, including the establishment of a cryptocurrency working group and potential stablecoin legislation, signal regulatory clarity and support for the crypto sector. However, investors are urged to remain cautious, given the uncertainties surrounding regulatory implementations.

In summary, while the market is facing turbulence, calling an end to the bull market seems premature. Long-term structural improvements and institutional investments may still provide positive momentum for the market's future growth.
