As to me, Bitkoin's volatility is too high. High volatility means high risk. That's obvious.
High volatility certainly means high risk but on the other hand, it is the uncertainty of the market value of bitcoin which is helping so many people in making of this much of profit as well. This volatile nature of bitcoin and other digital coins is helping them earn this much of fame and reputation and because of that, people are actually making more money. You have to take such kind of risks if you want to have something more in your life.
I'm not interested in coin with high volatility, usually with bots, the price is up and money is causing a loss. For this reason, large volume coins generally have less volatility.
