Going by your chart, Bitcoin indeed has been increasing well over time, let me say right from inception because that is what the chart also pointed at, if we look well towards it's direction of movement in price, of course we can't compare that to the way fiat has been performing, because it's a centralized currency.
Bitcoin could be of more advantage even if the market continues to react, the volatility is what brings about the set time to invest, hold or sell as the conditions may appears to each everyone of us intending to buy or sell.
