My own belief about the right time to sell is kind of funny whether the price is 1000k or even 2000k. I just follow my guts. At any point where I am cool with the price irrespective of whatever will happen after whether going low or going higher, I just live with it and even most times, I dont even follow the price until when I gather enough and ready to sell again then I start following and the reason is so that there wont be feeling of guilt in case there is an increase of price or happiness in case of fall in the price.
