Clearly, because you're smart enough not to give someone on another continent your wallet, as per the analogy.

I'd love to say it's because I'm smart, but inaccessible to bad actors on other continents is the default setting for my wallet. Hell, I'm not smart enough to even figure out how to change the setting. :)

It's the default for Bitcoin wallets also, but some users choose to "change that setting".

I've never had a mugger pull a knife on me late at night to take my bitcoins.

I _have_ had someone on another continent charge things to my credit card.

Did you have to pay for the charges to your credit card?

On average, yes.

I've never had someone on another continent take Bitcoin out of my Bitcoin wallet, and it's incredibly trivial to ensure that it stays that way. What's your point?

Other people have apparently had less success employing incredibly trivial security to keep their bitcoins safe.

Maybe because it's a new technology and we are just learning about it? Who told them to jump in anyway? Didn't they know hackers existed? I bet these are the same persons who leave their $3000 cameras or other gear unattended when they visit less lucky countries, and are surprised when they are stolen from them.

You mean that some people choose to not do the incredibly trivial things that are required to keep Bitcoins safe, right?

Perhaps we should meet in Istanbul with a cashed-up wallet and a very long pair of tongs?
