sell it or not, it's up to you, make the best choice for yourself...
If you are working to earn Bitcoin and you are living on Bitcoin then selling it now is a good opportunity but if you are not living off Bitcoin and choose Bitcoin as your future investment then Hodl is a wise decision.
If people sell their Bitcoin, sooner or later they will regret their decision. My asset once reached 2 bitcoins and I sold it, if I still hold it until now, I will be so happy, but..."I must strong and stop regret about the past" I mean even if people sell their Bitcoin and get profits, they will regret it, because the price will continue to increase. So hold is the right step
