This is a known fact if the price goes up it will surely go down. What happens if the price of Bitcoin falls to $1000 in 2018, will this be considered as a Worst Case Scenario or something else?
Eventually I think that this would not happen, I would believe that but current price will decline to $5,000 but to say about $1,000 it is really to low for it. But anyway who can know for sure, 3 years ago the price was like that.
