Well, it's not so complicated imho.
Pro: Easy interface on the Binance platform, you don't need to worry about technialities. ALso Binance is a big player and not some shady small platform without experience and/or built up trust
Con: You need to trust Binance as a platform. They are in a fight to become a "proper" trading exchange and had some legal issues in the past. Nothing is guaranteed, so never invest more than you can lose.
