So, is bitcoin money or currency?
If this is the choices, then none of the above. Bitcoin is not a coin, neither have a form of bank notes since it is decentralized so it is not a money. Bitcoin is not a fiat of any country so we can say that it is not a currency. If I will be choosing what is bitcoin, I think I will be saying that it is an investment, an asset most people use their money in order to have a profit through time.
