Banks cannot compare to Bitcoin. your keys, your coin, and many other things; no third party; problems with failed bank transfers; Since bitcoin is an investment, it will grow in value over time compared to fiat currency. From the start, the goal of bitcoin was not to become the future of money—I love that it was created on anonymity—rather, it was to be a better alternative to banks, because trust is the foundation which Bitcoin was built upon.
It is likely we see the difference between Bitcoin and fiat money. However, despite the thing that fiat inflation is inevitable we still can't say that it soon become useless and make Bitcoin as the future of money. I, therefore, say no, Bitcoin will become widely used in the future because of its interesting feature but never this gives a reason to kill fiat money and proclaimed BTC as a new global currency.
It was not the anonymity, or third-party issue but it is all because people are preferred to us it.
