Cryptocurrencies that appear to have flat charts when zoomed out are often the ones that will experience the most significant price increases when investment capital flows into them.
"In many cases, you'll also see a live chart button or a trading view button for a more detailed view, though this isn't available for every crypto. Believe it or not, though, the price isn't the main thing to look at. That's because it's common for a crypto to have lots of activity in the short term, even if the chart looks flat when zoomed out. In fact, the cryptos that are flat are often the cryptos that end up pumping the most when money starts flowing in."
