I think right now it makes more sense to store bitcoin and or other types of cryptocurrency for a number of reasons. Right now bitcoin has become a hedge asset, something that most people realize is a breakthrough technology and are storing it but not using it as currency. I think part of that reason is that using it as a currency right now is not as efficient as many other ways. Now it does have some features that are great and better than traditional money, but other features are still a major work in progress.
Using Bitcoin also triggers more problems in many countries of the world. First and foremost taxes. Apart from that, anything that is deflationary and tends to gain in value is preferred to be hoarded by people, that is not surprising at all. Even if it was easier to use as a medium of exchange or currency, people would still tend to hoard it. That is the same for fiat currencies. When interest rates are high, overall investments go down as people prefer to put their money to stay idle in exchange for a guaranteed interest rate for a specified period of time.
