Holding of your coins is a good idea and decision to take as now the price of transactions are becoming unbearably high. If the price of your tokens are low, for me, its to hold and see what it will turn out to become, otherwise, its to sell it so as not to be at the losing side. For me as a bounty hunter, I sell a few of my rewards and keep the remaining for the future if it will be come better in its price.
