Coinbase has denied allegations of concealing security breaches following a week of critical posts on X regarding its handling of customer losses. BlockTower founder Ari Paul accused the exchange of hiding repeated hacks, while a separate trader publicly complained about $1.2 million in missing funds. The exchange firmly rejected claims that it suppressed information about security incidents or mishandled user assets. The public dispute highlights ongoing tensions between crypto platforms and users regarding transparency and accountability for custody-related losses.
