That seem to happen that everything will be in crypto but the current financial system won't cut its ties to the economy. There will be fiat/digital fiat and cryptocurrencies. But only the few and strongest will remain. Banks will stay and they are not going to be kicked out of the community. They will join the revolution and forced to adopt crypto's. Though we are going to be our own bank but those banks will also upgrade.
Of course it will be, besides there is also no point on kicking out each other, because they have each advantages and disadvantages which makes them both sides of a coin. It will only depebd to people which will they choose or if they will prefer both. But mainly our economic is improving and moving forward to technology.
Crypto market side = no need to kick the current financial system.
Banking sector = they have to eliminate their competitor that has a potential to get their investors/depositors but sooner they figure out that they can't beat the system so they'll join.
