I think the reason of the price drop its because of huge fee increased holders are converting to bitcoin cash that is why the value of bitcoin cash is getting increases..
Don't let yourself get fooled. Bitcoin has been dealing with high fees for quite a while now, which large holders don't see as a problem. The only people complaining about this are noobs and faucet farmers not being able to move dust due to the higher fees. Bitcoin Cash having gone up is a natural development in the altcoin market, because if Bitcoin goes down, altcoins go up. On top of that we shouldn't underestimate how much influence big holders have with close ties to the Bitcoin Cash side -- they have the ability to pump the value to a 1:1 ratio within a day if they so wish. It's top notch market manipulation and nothing more.
