It does have something with Bitcoin. Bitcoin is a fully digital currency which isn't guaranteed by any bank or company. It requires its users to be way, way safer with their computers than almost anyone is.
Surely it depends on how much currency you happen to be holding?
At the moment, most holders of Bitcoin are people either speculating or experimenting with it. But if Bitcoin ever becomes a more generally used medium of exchange, users don't have to hold a lot of money for it to be useful, in the same way you wouldn't keep a lot of cash in your wallet.
