Bitcoin has begun December with a 4.85% drop, marking its worst start to the month in four years, according to Coinomedia. This decline is notable as December is typically a bullish period for the cryptocurrency market. Analysts are closely watching to see if Bitcoin will recover as the month progresses, amid macroeconomic uncertainties and shifting investor sentiment. The broader cryptocurrency market is also experiencing caution, with altcoins showing sluggish movement and a decline in market volume. Factors such as tightening regulations may be contributing to the early dip in Bitcoin and the overall market.
