A crypto's volatility depends on the market. It's volatility makes it more alive than just remaining at the same price for years. It will be announced as dead soon if it remains at same price for years.
News in crypto market makes positive/negative impact on its price. Good news makes it more popular among people and hence more people are buying it and hence increase in price, however on the other site if the news about a coin is bad like security flaws, theft, hacking etc.makes bad impact on its reputation and hence it's price will go down.
Maybe the topic means the level of volatility here in crypto which is actually very very high compared to stock markets. Even bitcoin, ethereum and other top coins considered a bit stable in their movements are still very volatile compared to traditionally regulated stock market. But this is because crypto market is still young and is still undervalued. This is our opportunity just like how facebook and google started cheap years ago. We don't want to miss this train.
