It is possible for new coins to reach top 20 list. I wonder if these coins will remain their position in the top 20 list.
Based on your images you're set list for 24 hours change, it's why all of them is DeFi token. I'd say it's almost impossible if these token will remain their position on top 20 because there's no coin/token will pump everyday... sometime it will dump or crash.[1] https://www.coingecko.com/en/coins/sushi
