I've seen few projects that decieved investors into thinking that they will list on binance or okex and Kucoin without these exchanges confirmation, my advice is once a project claim they are going top exchange do not hesitate to go to the top exchange social media, if the listing is legit the exchange will atleast say something about it. Wise up
Those kind of informations are only a way to attracting people to come into their project.
Speculators will buy their coin to sell it on binance or okex or other big exchange, and grab quick profit from it.
Just ignore that info if you get it from the team, big exchange like binance usually doesn't disclose the listing of coin.
