In a world of consumerism, bitcoin has been used as a digital money to pay bills in the fastest and easiest way. Many countries who doesn't have a legal regulation of bitcoin is entering the market in the simplest way of paying bills the fastest and accessible way. So it can be a commodity but not yet a currency.
What? How so? It is not being used to pay bills, and it is certainly not the fastest and easiest way. Almost no one accepts bitcoin for payment, and governments don't want to recognize it as a payment form because it would mean that their own one doesn't matter anymore. It's too slow, too awkward, too clumsy, and not easy enough to pay bills. If I want to pay my electric bill, I just sign into my bank account and enter the account number. Instant payment. Bitcoin takes several minutes and
it's not linked to your account number.
It's a commodity. A store of value in limited supply.
