Bitcoin is a decentralized online virtual cryptocurrency that are available in several countries. Bitcoin a cryptocurrency that has no definite DeFi system or any documents on banking systems. Banks cannot support bitcoin hence central government cannot control bitcoin as asual.
We need banks to make fiat into digital currency expecially in centralized exchanges. We need banks and banks need bitcoin vice-versa. Even bankers are holding bitcoin because they see value in it
In fact, if there is a harmonious cooperation between bitcoin and banking, it is possible that there will be an overall improvement with bitcoin trading itself.
but usually banking is always based on the rules of the country, there are still many countries that have not recognized the existence of bitcoin.
This is of course a problem in itself, because we know bitcoin can run without interference from banks, but it is better if there is cooperation it will be wide open for the public to be able to participate in it.
hopefully in the future it can be realized for all countries.
