Some projects that are startup are really gonna depend on dex like pancakeswap since the payment for cex is so high and expensive. You are right that mostly project can easily list there so as to other dexes on other chain. Since its a dex, a decentralized one format. If theres too much restriction or requirement we cant call it decentralized like big cex are doing upon listing. I may not comfortable with the project he have but he got a point about pancakeswap. No dex on bsc can match this, and it pretty well known on the altcoin ecosystem which I am aware too. Ive been using it eversince so I knew it is the top dex for bsc and its pretty popular even its swarmed by scammers.
