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
Yeah during the days of its existence it served as an tool for online transaction with much decreased transaction fee. This has grown in a short holding various functions from a technology to a best investment. Even looking it's growth and backing power countries too have regulated bitcoin acceptance. So we can strongly describe it as money.
