it depends how you define money..

bitcoin is certainly a medium of exchange, to me it also fullfills the store of value attribute regardless of volatility.

the thing you can argue most about, is the unit of account property, because stuff is always priced back to another currency like USD and BTC is not really used as the accounting currency, except for altcoin markets mbe.


i wouldnt worry about things like officially accepted money by law (legal tender), as most of the $/€ we use is technically not official money, its just created by banks out of thin air and is not issued by the fed or ECB. (in reality we have 2 seperated money cycles)
