Bitcoin is not a money, it is digital currency. Bitcoin is a digital asset you need to exchange to fiat in paper money or coins to be called money.
Yes bitcoin is money, just wait for the near future the bitcoin is became centralized currency. and its easy to us to used bitcoin just like money.
Not in my dreams that bitcoin become centalized. One of my favorite to this bitcoin is decentralized.
Digital currency is money as well, the name itself implies that, it is just a currency that is in digital form, your balance in your PayPal account is money, your balance in your debit card is money, and the balance in your bitcoin wallet is money as well.
Although Bitcoin just a digital currency, or exact more is the cryptocurrency, but you can exchange to real money. It like you can use Bitcoin for payment anything, but you must to exchange it to FIAT first, it is the requirement because there is no way to spend Bitcoin as a payment method, unless you are living in a country accept Bitcoin is legally.
