I must say all the points you highlighted are strong points Bitcoin can put forward any day as a favorite contender of the future of money, however I do not buy the idea of your 5th point. Bitcoin cannot be said to be a less volatile currency. Only recently, we were trading at about $1150 per Bitcoin, it came down to $752 and now trading at over $900, how else can volatility be described?

That aside, strong volatility is not a disadvantage, it in essence is showing high liquidity and which is what creates the enabling environment for demand and supply to compete effectively leaving us with a reasonable for Bitcoin.
