After a loss, we will all know where to begin. Several banks provided several services to make our life easy. But the results are taking our money as a transaction cost. I'm not happy with any kind of bank service, if you visit worldwide. Cryptocurrency offers us good privacy, but the government doesn't like it. Crypto can't be properly popular without the shadow of government.
Another big question is what happens to banks during another financial crisis when they totally crash again? Will they get another bail out paid by the public? What happens if they don't get a bail out? Are bank deposits gone then and people will be left with empty hands? There are a lot of important questions surrounding the fragile banking system. If you understand security well enough, cryptocurrencies are a good alternative where you do have more responsibility, but also more certainty as to whether your money could be gone tomorrow or not. Bitcoin does provide a great alternative despite its volatility.
