I invested in bitcoin only for the third point because Bitcoin dynamic prices give more chances to earn money by trading.
We cannot forget the fact that demand is largely increasing and that means more hands and more value. I sure would not want to give that up for anything yet until we are sure that yes, it is the right time to start spending for daily needs without huge volatility.

3) bitcoin price keeps on fluctuating and since it has begun it is increasing. So your money increases in value.
