What price did you buy bitcoin? If you have profited you can seel it now and buy again when its price goes to lower. But if you have intention to hold it for long term investment or you have marked profit that you want you can hold them. But I don't know and there is no one who will know its price movement. Clearly halving event has happened and make bitcoin supply will be reduced. Also I saw an information a few times ago who stated that fees transaction for bitcoin increasing rapidly, at least you have spend $3.5 for one transaction.
