if you are affluent people, you could hold your coin and wait until whenever touched its highest price was very good.
but for me, I'll sell when I needed it. maybe I'll sell every week or even month.
Me too. I sell it if I needed it. But for my coins only outside on the exchanges.
My funds in exchange sites are mainly for trade only and Im not idling them waiting for the right price to sell.
I do sold it whenever I sees profit then waiting again for the right time to buy.
