Holding for long term can be worthy if what you have is good or is a good prospect, then it would be worthy. If you want to hold for long time, make sure that the coin you are holding is not a bubble.
The whole idea of holding to success is determined by the coin you are actually holding. For a good coin, you will definitely be making some crazy huge profit in the long run, no matter how long you have to wait it out. One thing with holding is you are not bothered about the present conditions and you are only after the long term potentials and the demand that is going to make it skyrocket to the moon and as long as you have that patience, it is always not bad.
