If hardware wallets became unusable, would confidence in Bitcoin weaken, or would people adapt with new storage methods? Is this even a possibility ?
It pains me seeing unusual topic like this when op doesn't even know what is hardware wallet entails LoL.
I think you can take some time to read about wallet so you would not come up with unimaginable questions or post that has no logical meaning.
What's the point of starting multiple similar topics asking "what would happen if something impossible happened"? You already have 4 of them here and they make no sense, specially since you just keep opening these topics and go away!
Maybe op has not took highly concentrated liquor that might have led to post fishing without minding if they are similar or not. The liberty to create new posts without critical analysis whether they are good when read is what had encouraged scenes like this one.
