What is your thoughts on banks banning the sales of crypto do you think they are scared they will be replaced
I think also they are scared of crypto. If you check last couple of years, crypto market is rising very strongly. Crypto is one of biggest opponent for bank industry. That's why many banks try to create their own blockchain. They know sooner or later crypto will replace on bank and that's why they are trying to create their own blockchain.
I am not sure they are completely scared of cryptocurrency, because the blockchain technology ought to have been used by banks in a very long time, they will only be scared of cryptocurrency when it becomes means of legal tender, and since government is yet to pick interest in legalizing it, it is of no threat to them.
I even feel that banks are benefiting money in the cryptocurrency because most people are still holding it as means of asset now, and when they need to convert their profit, they convert both capital and profit into fiat and then store it in their banks, which means that banks will have more money to be able to give out loans to the public where they usually make their money from on interest. So, I think that banks are even more interested in cryptocurrency.
