Coingecko has a strong warning for people who are offering to expedite listing on their platform
Anyone claiming that they can list a coin or expedite the listing process on CoinGecko is a scammer.
You are asking for a huge fee without showing us anything, for us asking money without showing proof of their work is considered attempted scamming, I don't know how are you going to address this when Coingecko issued a strong warning and they have not changed their policy until now.
