the Bank of England governor recently said bitcoin has no value,
Those clowns don't have the slightest idea about the true meaning of "value"
[SMH].
Also even if it were not banned, governments can monitor all activity because basically everyone uses centralized exchanges and the blockchain is public.
Decentralized exchanges have become quite popular in recent years and more users are making the switch on a regular basis.

If they start using it in the right way
[as opposed to hodling], then they don't have to worry about the latter part that much.
since all the wallet apps will be removed from the app stores?

Regardless of what the future holds for
BTCitcoin, there will always be workarounds when facing such issues.
