There is no one who will tell you exactly what will happen here. That is why you should not panic - when in doubt while crypto market is crumbling one is certain:
this is the best moment to buy BTC, I am not sure about BCH at all as this is something new but with hindsight, I know that there is no need to worry about BTC.
Bitcoin has gone through a lot a current bearish market is nothing to worry about. Just HODL.
