Lawyers for Coinbase are set to ask a federal judge in San Francisco on Thursday to toss a class action lawsuit alleging the company botched the launch of bitcoin cash (BCH) transactions on its cryptocurrency exchange in a way that enabled company insiders to profit at the expense of customers.

Coinbase’s lawyers at Keker, Van Nest & Peters attorneys claim Coinbase insiders by necessity had to be informed about the launch of BCH on its platform and that all of its employees were explicitly barred from trading based on inside information.
