Bitstamp has just suspended its Bitcoin exchange services, because some of its operational wallets have been compromised. And, while it's nowhere near the scale of the Mt. Gox debacle (850,000 Bitcoins gone), the company says hackers still made off with 19,000 BTC or roughly $5 million. The service clarifies on its website (which now shows a splash page) that the stolen money came from its online wallets only and that the "overwhelming majority" of its reserves are stored safely offline. According to ZDNet, the service had $96.9 million store in offline storage in May 2014, but the amount might have gone down due to fluctuating Bitcoin values.
