to correct you:

its not MONEY
but is a currency

there is a difference
no government can decide what currency is. cigarettes in prison can be a currency, sexual favours/beer/cigars/pizza between friends in exchange for other favours can be a currency

governments can only decide what is or isnt MONEY

currency is a umbrella term which pretty much anything, which everything then fits into sub categories below the umbrella term. for instance
assets are investment holdings currency(gold, art.antiques,bitcoin)
commodity currencies are raw produce used to make secondary products (beef, wheat, gold, oil)

yes gold fits into 2 different markets..
but dont confuse the raw material utility of gold to produce jewellery/circuits(commodity) with golds separate asset holding market utility
to think that because gold asset is like bitcoin asset, that bitcoin also belongs in a commodity category.. bitcoin is not a raw material so is not a commodity

mortgage/credit agreements/insurance policies(the contracts/promissory notes themselves) are a currency but not money they are asset currencies (banks privately trade these behind the scenes)

money is legal tender of a country and authorised by law of the nominated/named country to be used to buy things and by law pay taxes/court fines/pay minimum wage

in short
crypto assets are a currency but are not money
