Bitcoin has value because it can be used to buy goods or services. If no one could ever use it to buy goods or services (i.e. it failed to function as a currency) then it would be worthless.
That's my issue. If BTC has value because it can be used to buy goods, what happens where everyone is HODLing and nobody is using it to buy goods? It will most likely see a continuous decrease in adoption and, as a consequence, a decrease in value because at that point you own a digital coin that is completely useless.
