Coinbase's data breach crisis deepens as TechCrunch founder Michael Arrington warns of serious security risks to users whose addresses and account balances were exposed. The breach, resulting from bribed overseas customer service staff, led to hackers demanding $20 million in Bitcoin ransom. Coinbase has refused to pay and instead offered an equal bounty for the perpetrators' capture.
