When you think all banks around the world with adopt blockchain technology? Or this will not happen too soon?
Banks are very prone to getting hurt by the crisis and can not really do something good to shield them selves. Though upgrading the system to crypto might solve some problems.
I don't think cryptocurrencies will be a problem to them. Banks are something that is inevitable to exist in a country since it is a great business if you will be looking at it.
As long as there are people using fiat, there will always be banks. Even though people are using cryptos, there will always be people that will use fiat since most of them are not used to use another currency and not that used to technologies and others are not really on cryptos to use on the society as a payment method. I'd stick on an investment crypto rather than a currency crypto.
