sell in May and go away!
What are your price assumptions for summer 2019?
Sell in May, go away and cry back later when you see your mates counting millions in future while you took few hundred or few thousand dollars. If you are not trader, I will advise that you never sell your coin now because what you see now is a shadow of what value bitcoin will reach during the next bull run.
I hope you are not seeing this as bull run already, this one is just a normal market ding great but when the bull run comes, you will know it yourself, and I am sure you already had an experience about the last bull, so why the rush, except you are trader taking profit which most traders still have their long term investment coins separately. By the end of this year, I expect bitcoin to peak at $15k before taking on the next journey next year.
