Bitcoin has recorded an 8% gain in the US trading session in December, contrasting with negative returns in Europe and Asia-Pacific. This surge is attributed to increased trading volume and US investor interest in Bitcoin accumulation, while other regions exhibit distribution trends. Despite these gains, Bitcoin's price recently fell to $85,800, marking a 3.5% decline in 24 hours following a significant selloff in November, which was the largest drop in Short-Term Holder Realized Price since the FTX crash.
