I think it's still got some way to go down personally, if it doesn't hold the $200 support level (September 2017 low) that it recently purged, the next support is around $140 (July 2017 low), below that is a scary $40 (April 2017 low) which isn't out the question I don't think. That said, like in April/May this year when the price doubled before crashing further, at some point there will be a substantial rebound that will double the price again if not triple it, regardless of whether it's got further to sink or not.
The ironic fact is it's only lost 4 months of value (September 2017-January 2018) so far, the issue is it's taken 9 months to shed these gains. The way I see it it could take another 9 months to shed another 4 months of gains to drop to $40. This is what happens when something does 100x in 12 months.
