As long as we can know how to minimize the risk, we can prevent the big loss in trading because whenever the price goes, we can anticipate and make a profit.
Yes, it is all about skills. If you are skilled to work on risks then you will never see volatility as an unwanted thing of trading but you will be loving it. I have seen people complaining about range bounded markets how BTC is doing right now. Because, they want markets to go on different price ranges so that they could make profits rather then sticking between 2 price levels.
If they can know that bitcoin can go to any price without having a deal with them, they don't have to complain, but they need to prepare themselves for the change in the price. The importance of this matter is how they can analyze the market, so they will have guidance on where the market will go. Although the market is unpredictable, they can know the pattern if the price will go up or down, so they can prepare before it's happening.
