Afaik binance is the company owner of the cmc website, and this tool would help her promote any shitcoin she accept to list either as a real trending one or as a paid service which is more dangerous.
I do not agree. The tokens that purchased the CMC boost and displayed in a different color, i believe that is enough 'warning' to anyone interested in it that the token is not organically visible at the top, but is being boosted to the top through payments made to CMC. I know that some greedy people would ignore common knowledge like this, but it should otherwise be easy to understand.
