Many bigger investor are in Binance exchange they will pump when listing new coin there, but although binance have worth with bigger investor you must be careful when investing with new coin after listing more than several day because price down and hard to get back on higher price, just investing with potential coin.
I think at some point you are wrong, in Binance they are choosing only those coin who are passed in their qualifications, also those coin has a high potential and could have bring many investors, binance exchange never failed in choosing a good one as far as I know it since I started here in crypto, among all exchanges, I trust binance so much that is it is the top exchange for me, and also OP advertise a new exchange, I think we needed some actual traders who had been already use that exchange.
