Update: GDAX halted trading of Bitcoin Cash shortly after trading began. A large number of sell orders are still on the hook at $8499.03 while prices on other exchanges remain in the $3500 range.
Coinbase, in a bit of a surprise announcement, notified its users that Bitcoin Cash is now available to customers that held bitcoin at the time of the August fork. While it was widely known that BCH support was coming, most expected it would take until Q1 2018 before Coinbase customers could claim and trade their BCH.
Bitcoin Cash prices responded well by spiking to an all-time high near $3500.
