Not the right time to sell I guess as price is moving upwards and same can be expected in coming months so the best thing would be hold them for next couple of months and watch what price it achieves and if it reaches $1500 then that would be the perfect time to sell.
Yes You are right that the price of bitcoin is increasing now again but selling at $1500 is not a good suggestion as if the holders will hold for longer then it is the chance that the price of bitcoin increase more higher in value so till that time the price of it will double up and the holder will be millionaire.
