Volatile markets are associated with high volumes of trading, which may cause delays in execution. These high volumes may also cause executions to occur at prices that are significantly different from the market price. Volatility is good for traders because it gives them opportunities. Even though the price of the underlying stock may fall, you're still earning steady dividend income.
If market situation is stagnant, it will be difficult for Traders to get profit, I can't imagine how traders can make profit if the Crypto market is not Volatile.
The volatility of cryptocurrencies is what makes it attractive to most of the traders. Imagine if this market is not as volatile as it is now, imagine if the volatility is same as the stock market, do you think it will be seen as an opportunity? of course not. Even more, there are some traders whose first engagement was in cryptocurrency not in stock cause most of the stock market traders cannot contain the higher risk of the crypto market unlike the stocks.
Volatile Crypto prices is a moment for traders to get profits. If Traders want to trade with coins that are not volatile, of course they will choose stable coins.
Trade a coin that is not volatile? of course that is stable coins, and who want to trade stable coins lol. missing your point here.
