I just sell it immediately I never trusts the price of bitcoin. For example: I get the payment of 100$ and received exactly 100$ in bitcoin I will sell it immediately never waits for the price to raise that is my rule because if you are getting paid in bitcoin you don't need to wait and hold your bitcoins because you already got what you have done but sometimes I receives a payment but I am out of town and when I come back I see some up in price it gives me profit lol otherwise I don't hold.
I think you should hold at least for a while because the price is always growing. It is already 6200$. You will lose nothing if you hold your bitcoin. Patience is required here, mate. If you want to gain profit, you should take the risk. Otherwise, you will get nothing.
I am not a trader, but if I am going to trade, I will take a risk based on my studies of bitcoin in the recent years. The so-called "Luck" is not required when it comes to strategy and tactics.
