If you are traveling and lose your credit card, but in a country that has a reasonably active Bitcoin scene, you can sell some BTC to pay bills while "over there".
This may become an issue for us.
Here is a case for having an online wallet, "travels anywhere".
My own knowledge to good to have a bitcoim is you can feel that you have an easy life. Just like you can shop online using your bitcoin, you can buy all the stuff you like. And also you have a finacial freedom. You can also share that to others how they can have their bitcoin also.
