Xapo stores over half a million bitcoins, and no doubt a few hundred thousand more as the owner is responsible for getting some very deep pockets involved in the early days and storing their coins too.
That's now somewhere in the region of $3 billion or more that could be had away.
You are right, many people here are taking security too lightly, they think that a company that holds giant amounts of money should just have an office in some building because "Bitcoin is on the blockchain". I guess they don't think that data can be stolen by physical means, starting from plain robbery at gunpoint and ending with sophisticated side-channel attacks or infiltration. There's no such thing as too much security and we definitely don't want to see another Gox-like incident with Bitcoin.
Yes, definitely. Those images have reminded me the “offices” where online casinos in Gibraltar have their servers. They are very similar. It’s not just about storing bitcoins, as the article says what Xapo have there is a data center to secure a lot of information. They are not stupid. If they could secure all the info in a cheapest place while at the same time keeping the info equally safe they would do it.
