(1) SO WHY BANKS ARE REALLY AGAINST CRYPTOCURRENCY? Cause the volatility of cryptocurrency markets are concerns over security and regulations. They've made many banks cautious about involvement in the crypto space. Some banks have even banned the use of cridit cards for purchasing cryptocurrency, reflecting their hesistancy to embrace the emerging technology full. If only the cryptocurrency are ready to make a good terms with the banks.
It is not as bad as you think, although cryptocurrency is reducing the earnings of banks in some ways, yet it is not so serious to the point that banks will now deem it as their core enemy. In my country, it was recently noticed that banks are losing tenths of billions of dollars to cryptocurrency yearly and that can't be a lie because, for instance, initially, I was unable to do any transactions without the involvement of banks and other digital transactions that will still later deal with banks, so banks are having it all at that time. And guess what, it was a huge extortion as they set the fees wickedly high, but now cryptocurrency has saved me, how many more other people would it have saved? So banks are losing in one way or the other due to cryptocurrency, but still, they are making their money even as they declare huge profits yearly.
However, what banks are doing that seems to be anti-crypto is not always the fault of the bank but the fault of their regulators. They have to obey the laws of the land even as the central bank and other regulatory agencies are often threatening them with restrictions and sanctions if they do business that is crypto-related.
With centralized establishment as well, banks have their share of benefits in cryptocurrency which shows that they are not entirely enemies because no matter how much crypto you bought today, there must be an equivalent in fiat in a certain bank as cryptocurrency buying and selling are merely being exchanging for fiat currencies, and banks always hold fiat. So, the government and regulators are to be blamed here and not the banks.
