Fiat money can only be used as a MOE (Medium Of Exchange).
Commodities can only be generally used as a SOV (Store Of Value).
Stocks, shares and other assets can also only be used as a SOV.
#Bitcoin, on the other hand, can be used as a MOE, SOV and a plethora of other uses. In fact, as time moves, we are slowly discovering/inventing new ways for its uses.
So #bitcoin is not really an "investment", it's a brand new way of life.
