I think this is a big NO.We know that every banks aim for one only goal.That is to centralize an decentralize financial system.And bitcoin is a decentralized cryptocurrency and if banks do happen many changes will happen in bitcoins.So i think having bitcoin banks is not good for all of us bitcoin users.
Correct, banks will aim to try to get control over the network so we must avoid the construction of a bitcoin bank, in a way this reminds me of the fight against the creating of an American central bank that happened and we know how that ended the Federal Reserve was eventually created.
There is no way bitcoin banks will be establish if people would not allow it, we want the same system that we are using now, we can simply transact online without the need of a third party and we know banks in real world is govern by the central bank and we are not sure if people who govern are really willing to serve the interest of the people. Here in bitcoin, we are all equal and we have freedom since we can transact anything and anytime we want.
Dont make a mistake, the only reason a bank of bitcoin has not been created is because it is not going to be successful because we know the truth but when adoption increases to the point the average person uses bitcoin then you can be sure bitcoin banks will being to exist because th average person does not know the truth.
