Yes a lot of scam coins coming to pancakeswap, I have even experienced this, buying new coins for this is new listed to coinmarketcap yes it can be profitable if you buy this early but when you are late in buying this coin you can lose your money. This coins are hyped by developers they will market coins having social medias and marketing their promos and offers but in the end if they will get the money they want, they will run out in the air, they will close their social media account and the price will dump till the coins has no value. So be watchful in choosing coin to buy.
