Well, in my opinion and analysis of the cryptocurrency exchange trading market, it's the volatility of cryptocurrencies that actually enables those that made investments in the digital currency to make incredible profit from trading their cryptocurrency when the price skyrocket to the point where selling or trading would be very beneficial to them.
If cryptocurrencies aren't volatile, it's not going to be very lucrative investment because it's price would be fixed and there is no way of getting to manipulate the market to earn more money from investing in the digital currency. Even other commodities changes in price but not as volatile as cryptocurrency. Is the volatility of cryptocurrencies a good thing? Yes, it's what sets it apart from other commodities in the world.
