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 don't know why you carry a wallet and a credit card, haha. I just have literally everything on my phone. All of my loyalty cards are on my phone. I use Google Pay. I have all my debit and credit cards from different countries on one phone. I easily pay for everything in all store by just tapping my phone. I'm sure this will be possible with crypto in the future too, but an obvious solution to counterfeit money is already here. Just don't use physical money. It also helps in the stores, so I don't need to count my change to make sure I'm not getting ripped off.
