It is important how we define the concepts.
Money is a change tool. We buy goods and services for money.
Bitcoin is also a change tool. We can buy goods and services with Bitcoin.
Bitcoin = Money
If that is you definition then I guess that is right bitcoin is money but an internet money, it is different from the money that we use
which is fiat. Bitcoin is a tool for online transaction and because of this tool we have a faster transaction which makes it very valuable
