News: Bitcoin experienced a slight pullback on Friday, failing to hold the $4,000 level and indicating a potential short-term bearish trend. However, the overall crypto market saw a $5 billion increase, with Bitcoin breaking above $3,700, suggesting some underlying bullish momentum. Regulatory news remains mixed, with Chile implementing crypto taxes and reports of increased darknet market activity, while institutional interest continues to grow in the long term. The performance of altcoins like Bitcoin Cash ABC also remains weak.
