off course can bitcoin not make banks disappear what will the world be like if there where no banks. Where do we all need to store our money i dont think it would verry save on earth on that moment.
Well, the answer is simple, we will save our money in Bitcoin if all banks disappear because of bitcoin.
I also think it can be happen, but I wish that one day bitcoin replace banks. I think banks are not that secure that bitcoins are secure and safe,. there are some issues with online wallets, but if we find a safe place to store our bitcoins then our money will be safer then any bank account.
