no not btc or anything but it was the eth that use that have the feature that they are comparing but sadly eth gone bad .
Are you talking about trading pairs with ETH, they are planning for the upgrade for a long time and the change they are planning to implement is really complex and it will take a long time for them to implement everything but we are yet to see how a major platform moving to POS will perform and whether they will be centralized like we expect all POS coins are.
you will understand it if your one of the people that use it before but eth could still be better in some aspects because the coin remains in the second spot .
Do not trust the rankings as everything can change easily, example is Doge and it is was no way near the top ten and one rally and it raked well above some of the top coins we thought will never change, so rankings means nothing and we will see changes according to the market movement.
