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?
I am not afraid of getting a low price of bitcoin but, what makes me scared of is that if bitcoin dies. I know there are bunch of coins could replace bitcoin like ETH but for me Bitcoin is still and will be the best all over the crypto world. Seeing bitcoin in cheap price is just normal because it is volatile hence expect that the price could fall or increase, in this situation, it is better if we will buy and hold it for a long period of time.
