I am a long-term holder, I often don't care much about market volatility, I focus on DCA and identify potential profit-taking zones when the bullrun occurs. I consider high volatility to be a good basis for BTC and the crypto market to get better media coverage, attract the attention of potential investors and create a foundation for the next cycles.
Volatility is one reason we get a chance to buy the dip. Many of us look for a chance to buy more once the market goes up and regret not buying when the price is low. Fortunately, the market has moved in both directions over time, and we have had a chance to buy cheap coins. One of my friends, "Crypto Library," was telling me that I was looking for a dip to accumulate more. But unfortunately, when the market moves to lower trend, we wait for further dump and miss that opportunity again.
Inasmuch as Volatility has its advantages, it also has its disadvantages too, Volatility has made the market really unpredictable, and for those who prefer to time the market, it can be really disadvantageous to them as they can not really predict exactly when the price is low enough to buy more and when the price is high enough to sell, one can end up buying, thinking its the lowest the coin can go and then end up seeing more reds, thereby resulting to losses, and one can also end up selling at a price he feels he's made enough profits, and then the real bull run kicks in and he regrets selling.
