It is very good to sell not your coins now around this time, because the value is not that high now to do it.
It will be much better if you wait a little longer and that you can sell it with a higher value, so you will have some profit.
But that is hard to know, because you never know what can happen with the value later.
Maybe this is not a correct estimation such estimations may not work correctly and bitcoin has shown a lot of unpredictable fluctuations so far.
yeah it is impossible to predict the price right now as bitcoin is fluctuating from time to time to be honest
i never sell all my bitcoins because i believe it will soon start growing and it will surely make me a lot of money soon
