In a significant legal development for the cryptocurrency industry, Coinbase has successfully defended itself against allegations of insider trading related to its 2017 listing of Bitcoin Cash (BCH). A U.S. federal judge has dismissed claims that the exchange engaged in market manipulation or allowed employees to conduct illicit pre-launch trades. The ruling marks a pivotal moment in shaping the legal expectations for crypto exchanges regarding transparency, market integrity, and user protection.
Background: The BCH Listing Controversy
In December 2017, shortly after Bitcoin Cash emerged as a hard fork of Bitcoin (BTC), Coinbase unexpectedly announced support for BCH trading on its GDAX platform—now known as Coinbase Pro. The announcement came just days after the company had publicly stated it wouldn’t list BCH until January 1, 2018.
This abrupt reversal triggered immediate market volatility. Within minutes of the listing, BCH prices surged dramatically. However, due to overwhelming demand and system limitations, Coinbase suspended trading within three minutes—leaving many users unable to execute sell orders at peak prices.
This sequence of events sparked outrage among traders who believed internal employees had advance knowledge and exploited it for profit. A group of plaintiffs led by former user Jeffrey Berk filed a class-action lawsuit accusing Coinbase of fraud, unfair competition, and breach of duty by failing to maintain a functional and fair trading environment.

Court Ruling: No Evidence of Market Manipulation
On August 7, U.S. Magistrate Judge Vince Chhabaria of the Northern District of California issued a decisive ruling: the plaintiffs failed to provide sufficient evidence linking Coinbase’s actions to illegal insider trading or price manipulation.
While the court acknowledged operational shortcomings—such as the abrupt halt in trading—the judge found no proof that Coinbase CEO Brian Armstrong or any staff members profited from non-public information. Critically, the court noted that the complaint lacked a coherent causal link between the alleged misconduct and actual market outcomes.
“The complaint does not adequately explain how BCH or BTC markets were manipulated,” wrote Judge Chhabaria. “Nor does it plausibly allege that Coinbase or its CEO had a motive to manipulate prices.”
Furthermore, the court rejected claims that Coinbase violated securities laws, emphasizing that cryptocurrency listings do not inherently constitute securities offerings under current U.S. regulatory frameworks.
Arbitration Dispute and Ongoing Responsibilities
Although Coinbase prevailed on most counts, the court denied its motion to refer the case to arbitration—a procedural strategy often used to limit public litigation. This suggests judges may be increasingly cautious about allowing crypto firms to sidestep judicial scrutiny through user agreements.
Importantly, the ruling also affirmed that exchanges carry an implicit responsibility to operate functional markets. As stated in the opinion:
“The most plausible interpretation under California law is that Coinbase has a duty to maintain a properly functioning market.”
This sets a precedent: even in the absence of fraud, exchanges can still be held accountable for systemic failures that harm users during high-volatility events.
Internal Investigation Clears Coinbase of Wrongdoing
Following the initial allegations, Coinbase commissioned two independent law firms to investigate internal trading activities around the BCH launch. Both reviews concluded there was no evidence of improper conduct by employees or executives.
These findings were instrumental in reinforcing the company’s defense and demonstrating a commitment to compliance—a critical factor in regulatory and judicial evaluations.
