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?
The worst case scenario that can happen to bitcoin to me is to fall to around $3000. However I doubt if this is going to happen as many of us bought bitcoin above $7000 and may likely not going to sell below that price as we would sell at loses.
