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?
This is probably the worst scenario. Because of the large percentage of its price will be dropped. Thus, it can be recorded in the history of bitcoin and this might cause to lose interest other investors to invest more in bitcoin again because clearly it is controlled by the whales called crypto currency market. And of course it does not happen because it will have a huge impact on the market.
