yes untill this time Cardano has third position on Coingecko higher than one level above BNB on fourth position. but honestly it is not reduce the value of BNB and enthusiasts of BNB . and some people know about value of BNB so its mean the value of the coins its more important than position on CMC or coingecko
Now the position is different again, in coinecko the third position has been taken over by Tether and the fourth position is occupied by Cardano followed by BNB in the fifth position, this is not only about a value, but also about the daily trading volume, so the position can be for the better, because when it comes to value or price, there are many coins that are more expensive than BNB, but they all don't make it into the top ten of the cryptocurrency rankings.
