Forks does not really impact price directly. In fact if anything theoretically it should actually decrease bitcoin's price since a portion of the funds in bitcoin are essentially transferred to another fork of bitcoin.

What really matters is the long term outlook of bitcoin.

In my opinion, that right now is very very positive. I would definitely think that all dips are only temporary, even if it lasts for 2 years or more. In the end, there will be a pump that revives the markets.
