Here is the statement from the President of the aforementioned Bank....So he is either purposefully missing the point of Decentralisation or he actually doesn't understand the difference between Bitcoin and a bank implemented cryptocurrency?.....
"I would suspect, down the road, that a number of central banks will have digital currency," he said. "When there is a digital currency available, other than the underground economy, it’s not clear why people would use bitcoin."
A cryptocurrency created by a Central Bank and controlled by the government will be pretty much like the electronic numbers we see in our bank accounts. What makes Bitcoin unique is the decentralization of the network, augmented by its scarcity (limited supply).
Shortly people will use Bitcoin instead centralized "stablecoins" because they don't want their hard-earned money to depend on the government actions.
