You should sell them right now,and when the price go down then buy more.
Its a common method how to earn btc in easy way. Buy low sell high.
i think bitcoin will never go down and i am sure bitcoin will rise more its price because i also never sell my bitcoin because bitcoin is very much stronger currency now.
I agree. Selling now will be a regret, Bitcoin is only growing. I don't know anybody who has used Bitcoin in the past, and has ceased to do so.
