No I do not think that banks can be destroyed by the bitcoin itself, the government will indeed stop this and the banks itself also has enough power to stop this easily.
i think no one can stop bitcoin not the governments and nor the banks, banks and governments have to admire the importance of bitcoin and they have to accept bitcoin as legal currency. the banks will also start accepting bitcoin in future.
Lol I think there is no necessity of government to legalize bitcoin, you can not intervene in the government to legalize bitcoin, because it is futile
but even so, I'm sure bitcoin will continue to grow
in fact if the governments will accept bitcoin then it will be more better for the future bitcoin. people will then certainly show more interest and they will invest their money more and more in bitcoin without any doubt and
