CoinMarketCap is owned by Binance and I always knew they are not going to be honest, but look what they are doing now with privacy coins!
They made ICP or Internet Computer as number one privacy coin that has nothing to do with privacy at all, and it is ranked above Monero now.
Even worse, they added WLD Worldcoin ranked at fifth place and they literally scanned eyeballs of people around the world for this crap
I am not sure if they are doing this on purpose or by mistake, but if you are still using CMC it's time to stop and switch to CoinGecko or some other alternative.

Correct me if I am wrong but I think this things are ranked based on their market capitalization, that is, based on the worth of their market cap, even cmc made this clear at the heading of the same you shared the link in your post.

So, when cmc decides to rank privacy coins based on their attained market cap, is it right to blame cmc for that?, I don't think it's right, I think they are doing their job at most, without any show of favorism or what ever, every coin is given their position based on their market cap, which I think is fair enough.
