For me it is not a good news, bitcoin is created to become decentralize it means no one really owns it even the goverment.
This thing is what i like most about bitcoin, then you say that theres a bank for bitcoin. It will make things more complicated.
Actually we have a bank for bitcoin and it is our wallet. So no need to use banks.
For now i am satisfied with wallet being our banks, because we can control it and it makes transactions more easier.
There have always been banks for bitcoin. Coinbase, Luno, exchanges that you can convert to fiat are all banks as far as I am concerned and that is exactly what that project was offering. The essence is just for conversion, even though it has wallet capabilities, but security wise, no one would ever want to leave their bitcoin one day getting dwindled on an exchange wallet. I really do not know why OP would be so happy regarding this anyway, not like it is a new thing.
And was sometimes bitcoin not created to become independent of banks? Banks have to comply with a lot of regulations and are under financial supervision. This causes the state to have control over the currencies. I don't think it's about the idea of decentralization.
Sorry to deliver the bad news. Exchanges are all going to be regulated as they serve as banks anyways. Unless you want to do without fiat, then you will always have a business to do with them. That has not stopped bitcoin or some other cryptocurrencies from being what they are, but until we can have a system where we can spend our cryptocurrency without having to convert to fiat, then we do not have anything to do about it.
