Veteran trader Peter Brandt warns that Bitcoin may be forming a bearish reversal pattern, potentially leading to a drop into the $70,000 range if it breaks support at $90,000. Currently trading at $97,201, he suggests a possible low of $76,614. Brandt also highlights a bearish head and shoulders pattern for Cardano, which could plunge if it fails to hold above $0.91, while XRP appears to be forming a bullish continuation pattern.
