KEY POINTS
  • Bitcoin had been coasting in recent months on fairly low volatility until "things exploded" Wednesday, says the cryptocurrency fund manager.
  • Kelly says bitcoin tanked because of concern over a "hard fork" or "effectively a software upgrade" in bitcoin cash.
  • Traders got concerned that the bitcoin and bitcoin cash markets would run into a slow down or "chaos" after the software upgrade.

Bitcoin had been coasting in recent months on fairly low volatility until "things exploded" Wednesday and prices tanked more than 10 percent, BKCM founder and CEO Brian Kelly told CNBC.

Kelly, a cryptocurrency fund manager, said the sharp downturn had to do with bitcoin cash, which splintered off in August 2017 from regular bitcoin with the goal of being able to process more transactions.
