I would define crash as anything below $3,000. We are a long, long way from that. Bitcoin is already stabilizing and has refused to go below $7,000. The consensus is that we could make a move to $10k anytime soon.
At least we must think about the $6000 should be the next bottom of the bitcoin itself, due to the a lot of the FUD from the bitcoin cash fans to the bitcoin in various forum and the cryptonews site especially about the bitcoin cahs supporter's site just like bitcoin.com
The low bottom value of bitcoin too cannot be predicted at present. The value has declined in a much steeper manner and still continues. Now the alts too have been experiencing dump, so soon can expect price increase altogether. This can be used as an opportunity to into bitcoin and altcoins.
