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.
I think cryptocurrency can really stop the spreadout of fake money but in cryptocurrency there is too much problem that you could encounter like the risk, volatility and security.
