The main reason (why banks don't like btc and other cryptos) is the loss of profits.
Transactions made via blockchain kills transactions made via banks.
But the topic is essential! It should be upped!
Obviously and it's true, transactions that have been done by bitcoin users do not go through the bank, obviously they know that the transactions are very large, they do not receive some of these benefits.
is it possible the bank will plunge to be able to complete and participate in bitcoin transactions, possibly of course there are, but there are obstacles that will be experienced by the banking of course. because of the difference of the transaction.
