1) Do you think Roger Ver with his support to BCH will Kick bitcoin price and replace it with BCH or bitcoin will survive ?
Many are still believing him but no way it won't replace bitcoin and btc will live.2) Do you think this crash normal (7,800$ to 6,200$) or intended 
Yes, it happened even before at lower price.Well I am in favor that bitcoin will live for a long time and that must be forever, because it has been established already and its volume has a strong foundation in terms of asset. That price will have to fluctuate but don't think it literally as crash, because normally it occurs specially more dumps is happening everyday. More will be doing day trades specially those long term holders.
In the future, these debates will stop about blocks and people will get into supporting one bitcoin. No FUD and no any other attacks and interruption to the network, we will all live. I don't believe with those thrills that they are doing right now because in the end they will be getting back to bitcoin. They are whales and they knew it on how big bitcoin is.
