5. Bitcoin isn't real money: like I said earlier, Bitcoin is considered legal tender in some countries and most stores and employee accepts Bitcoin as a mode of payment so Bitcoin is real money.
Where exactly do most stores accept BTC? Because I have a feeling that it's the opposite and only a tiny minority of businesses accepts BTC.
I think it's foolish to argue that Bitcoin is not widely accepted, but not widely accepted money is still money. Bitcoin has liquidity, fungibility, it's resistant to damage and has a lot of other properties that are desirable in money.
