You don't need to carry it around in your wallet, right? Makes it harder for people to steal your money, huh? Well, while yes it keeps pick pockets out of business that doesn't mean your digital money is safe. You know hackers steal money from people's accounts all the time? But hackers shouldn't be your only concern. According to a blog post I saw somewhere on the net, the government is also very much interested in stealing some of your money. Whether those allegations are true or not, the fact is if you have money in you Paypal account, Bitcoin wallet, or elsewhere as long as it can be accessed online, that money can be stolen. The best way to be prepared for such an eventuality is by having some cash at home. Get a safe. Withdraw some cash from your account and hide it there. You never know when you'll need it.
