Banks are the main industry that mooves the economy of each countrie since all transactions are made from and with them, companies hasnt any option outside them to make their deals and protect their money.
Bitcoins wont be working with banks, until the countries figure a way to tax the crypto world, as well banks with their fee, nowadays if you go to your bank and let they know you wanna become a trader they will support, because they thing you going into forex and trade currencies, if you say you wanna go crypto world i dont know but im pretty sure they will warn you that you can loose those money
I don't really know how bitcoins could be working with banks
But if you actually meant to say that it is banks that are not going to work with bitcoins because governments can't figure out a way to tax the cryptoworld, then I can't possibly agree with that. First, banks starting to accept bitcoins may exactly be the way how governments are going to tax bitcoins. And, further, governments don't need to tax bitcoins specifically. People here seem to be obsessed with the idea that governments are searching for opportunities to tax, for example, Bitcoin transactions. But why would governments ever want that? At max, they might want to tax profits earned via bitcoins but they don't need anything special for that since they basically already have everything in place (see income tax)
