Coinbase CEO Brian Armstrong has addressed criticism regarding the app's push notifications for gambling-like features, such as sports betting and Bitcoin price predictions. Zcash founder Zooko criticized these features for targeting young and economically disadvantaged users. Armstrong responded by asserting that adults have the freedom to spend their money as they choose, likening early investments in stocks or cryptocurrencies to gambling. However, Armstrong acknowledged the need for better user protection and transparency. He emphasized the importance of clear information disclosure and AI-driven financial literacy tools to help users make informed decisions. Armstrong also suggested that users should have the ability to customize their app experience by setting preferences during registration, allowing them to enable or disable certain features. He concluded that societal norms, determined through democratic processes, should guide the acceptability of behaviors like sports prediction markets, rather than private companies.
