Odaily News Robinhood Markets Inc.'s cryptocurrency trading volume more than halved in April as retail investors' interest in digital assets cooled, outpacing declines at rival exchanges. Robinhood said in an operating report on Wednesday that nominal cryptocurrency trading volume was $10.1 billion last month, down 57% from $23.6 billion in March. It's still up 173% from the same period last year. In addition, the stock trading platform's average daily revenue trading volume (used to indicate the number of transactions per day that generate commissions) fell 43% to about 400,000. (Bloomberg)
