You seem new to crypto world. We had one major hardfork few months ago. Nothing to fear.
If you meant prices then there maybe little fluctuations in price but in long run Bitcoin will strengthen back to stronger position like it is now. So you are free to make your strategies without fearing pre or post fork situations.
While if you meant working of Bitcoin or blockchain. There maybe 1 or 2 days halt in performance due to double performance. But after that you can conveniently use both coins if you have them with private keys.
Im new to bitcoins too but already have an idea on what will happen after this another fork. I believe bitcoin price will continue to up what ever may happened after this new fork.
