The most annoying part about these crypto exchanges is their ranks on rating websites e.g coinmarketcap, I wonder how this website get so blind and over look the fake volumes and watch trades, they need to be exposed
Because of the API signal they provide, the ranking sites shows such data. I don't they'd prefer a manual option for each exchanges, however they should add exchanges hand pick only. Also, you can watch Coingecko for an extra layer of trust score. It's seems moderately fair.
