Regards the BTC price at the moment I assume that the price will fail back to 4300$ after the fork. I believe in bitcoin and I believe it will go up again after the fork, but for now it keep going down.
Another thought is the price goes down due to the amount of people selling their BTC since they don't wanna face the fork I am not sure if that has an effect, but I will not join the fork. I will sail after it
I have just opposite opinion on this, many buy cuz they know it will be bitcoin to bitcoin gold ratio 1:1 like with bitcoin cash.
They hope that with this they can earn some free money and that they will have some more bitcoin after this.
Price movement is small and for the moment expect, 6000 will be broken after this fork.
