Amidst a host of problems surrounding the inclusion of Bit Cash (BCH) into Coinbase\'s digital asset exchange (GDAX), trading was resumed on December 20th with some 11,591 BCH-USD transactions (the only exchange pair currently listed) taking place within the first 15 minutes of the books re-opening. This BCH figure equates to approximately $39m.

The previous day\'s launch on GDAX came to an abrupt halt after only two minutes of open trading. Excessive volume led to a volatile tripling in the cryptocurrency\'s value to over $9,000, and threatened to destabilise the market for other exchanges. Bitcoin Cash, a hard fork off the Bitcoin blockchain which was initiated in August, was listed on GDAX after months of study and review.

GDAX re-opened for post-only access at 0900 PST on December 20th, allowing Coinbase users to submit transactions but not allowing for their execution, and these early transactions (worth over $4,000) were quickly completed two hours later, when full trading resumed at 1100 PST.

The state of the BCH market has caused widespread discussion and controversy in the industry, with allegations being made that insider trading might have taken place in advance of the Coinbase market launch. Coinbase CEO, Brian Armstrong, has promised a full investigation into these allegations, in the light of the massive price hike which occurred prior to the company’s formal announcement of BCH trading.
