To provide a concrete example, I use Bitcoin where I don't trust a provider to not charge me again in the future.

Some banks give you some tools to protect against this case like generating debit card numbers with an exact balance on it. But Bitcoin generalizes over the case.

Your comment is the sort of all-or-nothing mentality that I don't understand. I look at banking institutions vs cryptocurrencies as different options just like credit cards vs cash: I want to be able to choose, and I don't want to be limited to one single solution.

It's kinda of like the decision between an iPad vs a techie's laptop. I think the most common cases (e.g. my parents' needs) are best served by an iPad or a banking institution, but it's dangerous when someone begins telling me that I don't need such a powerful laptop.

All too often I see cryptocurrencies dismissed with the condescending implication that nobody is capable of evaluating the trade-offs.
