At the moment there is no exact answer.
I think that not all people are ready to abandon the usual banking system in favor of Bitcoin. It is very difficult and global solution. We cannot say with accuracy that it is better, since the adoption of Bitcoin as the base currency can lead to catastrophic consequences (crisis, unemployment, etc.).
Logically, Bitcoin is much more mobile and convenient than our banking system. And I hope that in time we will be able to use bitcoin for the benefit of people.
