Zcash founder Zooko Wilcox-O’Hearn has sharply criticized Coinbase for aggressively promoting prediction markets and sports betting to its users, particularly those with limited financial knowledge. In a series of posts on X, he described his encounter with a young, financially unsophisticated user whose Coinbase app was prompting them to gamble on sports events and Bitcoin’s price. “I hate this with a burning passion and it makes me ashamed to be part of this industry,” Wilcox-O’Hearn wrote.
Coinbase CEO Brian Armstrong responded by defending the platform’s approach, citing libertarian principles of personal freedom. “Consenting adults should be able to do what they want with their own money, as long as they’re not harming others,” Armstrong argued, adding that no investment is perfectly safe and that defining acceptable risk is subjective. However, he acknowledged that aggressively promoting high-risk products to unsophisticated users “doesn’t feel right.”
Armstrong proposed several possible changes, including clearer risk disclosures, AI-powered financial literacy tools, and personalized onboarding where users could enable or disable certain product categories. He stressed that private companies should not be the ones drawing the line on such matters, leaving that to voters and lawmakers. Wilcox-O’Hearn later thanked Armstrong for the thoughtful response, ending the public exchange on a respectful note.
The debate has reignited discussions across the industry about balancing financial innovation with consumer protection, and how exchanges should handle high-risk offerings like prediction markets.
