People are getting info about November fork, we might see drop below 3600 in next 48 hours and before Nomber possibly to 3k or less, but 3k will probably be a huge support. Also 1/3 (33 %) of miners changed from btc mining to bitcoin cash mining. People will FUD, sell now, buy back later when bitcoin dips. Segwit 23 August was already priced in and we risk fiasco of unsuccessful segwit transactions and/or lost coins because of segwit security vulnerabilities. Even Slush pool CEO (inventor of bitcoin mining pools) said that he first needs to see segwit transactions, until then no one knows.
