Ether (ETH) prices might see a correction, Singapore-based digital assets trading firm QCP Capital said in a morning note. The trading firm said it is still cautiously optimistic about the long-term potential of ether. Although ether has sailed past $4,000, its highest price in two years, QCP writes that it’s observing a shift in market sentiment, marked by negative risk reversals. These reversals measure the difference in implied volatility between call and put options and have turned negative, likely due to the low probability of a spot ether ETF being approved in the near future. QCP also wrote that it is concerned about the amount of leverage currently in the market, but traders will quickly buy back any dips. Excessive leverage is said to have caused the May 2021 crash, where prices fell by 30% over the course of 24 hours, and a 10% correction in bitcoin’s price in January.
