BitFinex down due to Bitcoin security breach - 120k BTC stolen
As much as the joke about bitcoins "take the money and run" exchange business model is bandied about, how do people actually suggest securing exchange wallets?I'm sure it's talked about, but I've never really found a straightforward explanation of how it should be done - is there even an agreed upon set of best practices? If so, why are these supposedly sophisticated exchanges not able to successfully apply them?
