1203 ET - Major cryptocurrencies are posting big gains, driven in part by major surges in the amount of trading volumes over the past 24 hours. The Treasury Department steps up its buyback operations for government bonds, which in turn sends yields sharply lower. In turn, riskier assets like cryptocurrency are jumping, with bitcoin up 6.1%, ethereum up 9%, and solana up 6.8%. Trading volumes are up big over the past 24 hours, with ethereum practically doubling its trading volume in that time at $49.3 billion, according to data from Coinglass. Bitcoin volume is up 57% to $76.5 billion. Low trading volumes has been considered a factor for sluggish trade in cryptocurrencies in recent months by analysts.
