Bitcoin has been touted as a crypto-currency, capable of replacing fiat currencies but the reality today is that most people prefer to hold bitcoins rather than spend it. Can we really say it si a currency when a large number of bitcoin users treat it as an asset?
Maybe it depends. Four countries wherein it is already legal, it is a currency that its users can use to buy the things that they want. For investors wherein it is not yet legal, it is an asset to be held for a long period of time as its market value is increasing. Maybe it relies in between being an asset and being a currency.
