PANews reported on December 21 that according to Bitcoinist, analyst Maartunn pointed out that this Bitcoin pullback may be related to the large amount of selling activity on the Coinbase platform since October 26 (when BTC was trading at $66,000). The increase in selling pressure clearly shows that the market has shifted from a bullish market to a market full of fear and hesitation. The combination of reduced buying activity and increased selling pressure shows that the market is struggling to maintain its upward momentum. Bitcoin has experienced a major pullback, falling 15% from its all-time high of $108,300. This price drop marks a sharp shift in market sentiment, which has quickly shifted from extreme bullishness to uncertainty and caution. As altcoins have been hit hard, Bitcoin's pullback has raised concerns about the sustainability of the recent rally. In addition, Bitcoin is currently testing the $92,000 support level.
