Because nobody knows when the market will start to rise. But, as I expected, this time not from Sales just stopped and watched the market and appreciate this time with I family on the grounds that in a few months the market will start to rise. So this time there is no compelling reason to offer. I don't know myself and I can't predict the increase. But if the coin that I hold is valid and worth holding, I better hold it or I have to cut my losses.
In my own opinion, it true you cannot predict when will the price of your holdings will increase. But i think its much better to invest your money and wait for its price to reach a high price that you are contented, then you will start to selling it for you to earn more bigger profit.
