Roger Ver's support to BCH will make an impact to BTC's price, that is a fact, but this will not replace it. BCH will still be an altcoin and will never be the "real" BTC in which they are targeting to do. I'm positive that BTC will always survive in any type of attack people throw at it.

We all know that BTC is very volatile and a "crash" in its price is in its normal realm. There's nothing out of ordinary in it. Whether it will be intended or not, we couldn't know the correct answer to it. We just keep in mind that cryptomarket is being manipulated by the whales and will always do what they need to do just to profit in any market they enter.
