Global markets start the new year on a gloomy note, but Bitcoin defies the trend with a "red hot" start.

The global market started the new year on a gloomy note, with Bitcoin rising against the trend by more than 6% to reach $45,300. Investors are optimistic about the approval of the first spot Bitcoin exchange-traded fund (ETF) in the United States, but it is still uncertain whether the actual approval will become a reason for speculators to profit. Digital assets are also benefiting from expectations of a rate cut by the Federal Reserve. The weakness in the stock market reflects investors' repricing of loose monetary policies, and cryptocurrency prices may fluctuate. K33 Research estimates that there is a 75% chance that the SEC will approve the Bitcoin ETF, and a 20% chance that the Bitcoin price will rise further.
