LOL.. going by your definition, most of the coins in top 10 right now are "old coins". Bitcoin was invented in 2008 and was first mined in 2009. Ethereum ICO happened in 2014. Ripple's initial release was on 2012. In case of Cardano, the ICO started in 2015. Dogecoin was first introduced in 2013. So going by your definition, almost all of the top coins are "oldies". Among the top 10, I could find only Uniswap, that was created at a later date (created in 2018 by Hayden Adams and listed two years later in 2020).
