$50 is a realistic CAKE price in the future in my opinion, but as I mentioned that currently Pancakeswap is not the only token swap place, there are other token swap places that are an option and I think that's a good thing. If the price exceeds $50, then it is no longer realistic.
For BSC network users, they mostly use Pancakeswap to complete their exchange or swap tokens, although most of these users only use Pancakeswap to that extent without seeing Cake coins so staying at $50 in the future will also be very difficult for Cake.
