You can't store value in something whose only purpose is to store value. Insofar as you can save an asset, it's because you're defecting in a game where other people are actively using it to provide the future value you want to claim later. If everyone only ever saved Bitcoin, then who's going to buy it when you want to sell it later? Someone else who wants to store it forever? The reason saving currency in a bank works for the economy is because they're loaning out the back to productive businesses and then giving you some of the interest. This doesn't work if you keep it under your bed/in a crypto wallet. (Maybe you could solve it by paying people more to take risk, but I don't think interest is that attractive to people?)
