I agree with this idea a bank bitcoin bank. I think that is also because I want btc to be regarded as a currency that we can store and solve a lot of things.
If the physical bank forms, bitcoin should get world recognition to operate in public, this is not an easy thing and takes time and process. Other problems will also arise such as the disagreement of fiat banks globally. I think these two parties must unite, meaning fiat banks must accept bitcoin as a legitimate currency, of course this also must get approval from the government.
