Multicoin Capital co-founder Tushar Jain said cryptocurrency-market optimism has become somewhat excessive, describing sentiment as "slightly euphoric" and saying a short-term correction or sideways consolidation would not surprise him. He advised investors to focus on the longer term, avoid overtrading and hold high-quality assets with strong investment claims rather than attempt to predict every short-term peak and trough. Separately, the Coinbase Bitcoin Premium Index, which tracks the Bitcoin price gap between Coinbase and other major global exchanges, fell to -0.0198% from 0.0013% the previous day. Its return to negative territory suggests weaker short-term buying appetite among US-based investors. This is not investment advice.
