So that would not really constitute a bank that stores currency.
(I have nothing on crypto currencies, btw., and if it gives a feeling of agency to use them I applaud it)
If you start from there, you'll never understand bitcoin. I own bitcoin precisely because it is not what economists, bankers and politicians want me to own.
This thread was not about understanding bitcoins - but banking.

It doesn't really make sense to own something just because someone else are saying you should not own it - but whatever floats your boat and as long as your own the consequences of your own actions.
Now that stonk people are in to BTC and it's worth is much higher, it's volatility is far less. It's still a speculative asset and with plenty of risk, but it's definitely a store of value for at least some % of one's savings.
