in the future people are not going to use fiat currency they will addict to use crypto basic currency to use day today activity.
Not totally. Fiat still give convenience to people especially under developed countries so I think they will be the only reason for banks to strive and stay alive.
Some people just make sick comments. So you think that Bitcoin is able to make banks fall or what? Dont you know that banks is always involved in everything that has to do with money? When you invest into cryptocurrencies the companies dont just swallow the money and make it disappear in thin air, the money goes straight to the companys bank account.
