what happens to the bank? they do like us, they take advantage of bitcoin and speculate with a lot of means and get even more in their pockets
Actually, Digital currencies are a very big threat to the banking system. The features that these currencies some what oppose the way of banks and are more preferable. For instance, bank keeps track of our all transactions whereas bitcoin transactions are anonymous.
Bank can seal our capital any time if we break some rule, but nobody can control digital assets. Above all, keeping money in the bank does not give any real profit but bitcoin does.
As in the quote, digital currencies were a threat to the banking system. But being centralized makes people believe in the banking system. Keeping money in the bank does not give real profit, but bitcoin does. Same time the risk with bitcoin is big, banking does not have it.
