Bitcoin prices rose above $90,000 today, reaching a near three-week high; however, fund flows in derivatives and spot ETFs indicate that traders remain cautious, suggesting limited market confidence in further price increases. Data shows that despite the price rebound, demand for leveraged long positions in Bitcoin remains stable, and the Bitcoin futures basis is below the neutral threshold, currently at an annualized premium of 4%. Since December 15th, Bitcoin spot ETFs have recorded net outflows of over $900 million. Furthermore, Bitcoin put options traded at a premium on Saturday, indicating increased demand from professional traders for downside protection. (Cointelegraph)
