Eight months later, Coinbase says their internal investigation into insider trading is complete. The company told Fortune they found no evidence of wrongdoing and did not terminate any employee as a result of their investigation.
“We would not hesitate to terminate an employee or contractor and/or take appropriate legal action if evidence showed our policies were violated,” a company spokesperson said to Fortune.
When Bitcoin Cash, the controversial hard fork of Bitcoin, was created in August 2017, Coinbase told users they had no plans to support the coin. They later reversed that decision, telling investors the exchange would support Bitcoin Cash by January 1, 2018.

“The launch did not go as expected,” Coinbase Vice President and General Manager Adam White said. “We understand why many of our customers and members of the community are upset.”
Coinbase told Fortune it hired two seperate law firms to conduct independent investigations on the matter.
“We can report that the voluntary, independent internal investigation has come to a close, and we have determined to take no disciplinary action,” the spokesman told Fortune.
Coinbase did not wait on the results of the Bitcoin Cash investigation before adding new coins to their exchange. Last month, Coinbase added Ethereum Classic (
“We are making this announcement internally at Coinbase and to the public at the same time to remain transparent with our customers about support for future assets,” the company said on its blog. “Going forward, you should expect that we will make similar announcements about multiple assets.”
