Common mistake and for sure you arent the only ones who did sell off too early yet no one did anticipate for price to cling up as high as 15k as of this moment.
I do even believe  that we might be seeing this number on next month but surprisingly it did really reach out in no time.Thing here is that you do sell off
when you are in greens and that what matter most.Dont feel on that having some regrets yet you can buyback anytime.Question if the price would dip down?
No one knows neither there would be some pullback or it would continue to go in 16k.So its a matter of risk management and this will vary
into each person because we do have our own will on what would be the actions that we would make next.
