Agreed. BTC is still so immature that people are mostly accumulating it (HODL). If we reach a critical mass of HODLers I assume we will see it be used more as a means of payment for non-illicit goods and services. I have used BTC to by gold and silver (from APMEX), which is the oldest forms of money known to man.
BTC is working fine as a currency inside that crypto space.It could be debated what BTC really is. Is it 'money'? Is it property rights to digital scarcity? Is for example Steem a currency, digital right to digtal scarcity or a preference share (that gives dividends) or perhaps a tribrid of all three? I doubt BTC can be analyzed​ from a fiat perspective (when will all people by coffee with BTC etc).
