Bitcoin is certainly money but not as we know it . While fiat currency is certainly being debased on a daily basis it is being done in a somewhat stealthy manner and low interest rates means we don't really see the inflation that is going on. BTC on the other can swing wildly up and down in a single day and that volatility makes it difficult to use as money because how do you price anything. This will be a challenge for all cryptos going forward & even if mass adoption does happen I can't see crypto volatility disappearing anytime soon.
