In my understanding, Bitcoin was created as a currency an electronic form of it. But it is currently used as a form of investment. Do you think this will always be the case, and Bitcoin will never really be a type of currency?
It's not a currency as per definition by this world's standard but we can call it as a currency as it has a value although it's just a tool
for online transaction. It's unique because it has limited volume and because of that some investors who sees the increase of demand in bitcoin in the future
has invested in bitcoin as they want to store their money and watch it grow.
