Bitcoin improves over the dollar (and other fiat currencies) where it actually counts.

- The dollar is not very good for storing “just in case”. (loses value due to inflation)

- You can’t carry cash around or the police will take it, and if you leave it in a bank, you can have your account frozen and the money drained if you use it for purposes deemed unacceptable.

You cannot own dollars the way that you can own bitcoins. It is not that Bitcoin comes at no risk; it is rather that you can always expect to have **the same** fraction of the total later on, if you secure them properly.
