Everything in our lives is now in our phones.
Why should we carry a wallet or credit card?
I really do not understand that.
millions of counterfeit money is printed every day
There's a lot of fake money in the world.
Can credit cards prevent this?
Bitcoin will kill them.
in my opinion no. because if bitcoin kills it all the same changes the official currency in that country. and you know if there is currently no country that officially recognizes bitcoin as the official currency in a country.
