Zooko said Coinbase was pushing high-risk sports betting and Bitcoin price prediction products to inexperienced and financially vulnerable users, while CEO Brian Armstrong defended user choice but said aggressive marketing to such users is inappropriate.
A public dispute emerged over how Coinbase presents high-risk products in its app after Zcash founder Zooko said the platform was pushing sports betting and Bitcoin price prediction features to young, inexperienced, and financially vulnerable users. In posts on X, he called that approach shameful. Coinbase CEO Brian Armstrong responded by defending the principle that adults should control their own money, while also saying aggressively promoting high-risk offerings to inexperienced users is inappropriate. He pointed to disclosures, AI education tools, and user preference settings as possible safeguards. The episode highlights a broader tension in crypto and consumer finance over balancing user autonomy with protections around speculative or gambling-like products, and it may raise concerns about regulatory scrutiny, reputational risk, and investor confidence.
