Damn, i really feel sorry for you because you did sell a bit early for sure.
I doubt that what you said will come true. Bitcoin crash will not come before $10000. If you buy now you may actually make a decent profit but you've got to be patient and wait till at least the end of teh year to sell your entire position.
And since it is such high values for bitcoin right now, you need to time your sell orders well. Don't hold onto your bag forever.
No one is stopping anyone from selling and in fact I will be willingly waiting for that crash so I can maybe get in some price I could not before.
