The entire Altcoins mostly are dependent upon Bitcoin's price movements except for the very few coins. Holding Bitcoin is good only up to the amount of money that you can afford to lose considering the volatile nature of it. I don't personally hold it longer but trade it for gains either in the red or in the green market. But holding favorite Altcoins I still do, I even mine them or work to collect some of them, while I am hopeful of its rise in the future but I hodle not primarily of profit but for fun. If I would like to gain, I would have to trade and earn small rather than waiting for an unpredictable rally.
