Every coin becomes useless for any purpose if we don't see how it is utilized by their consumers. Holding it wouldn't be good or may not be of importance if it isn't really been moving with actual usage like if the volume goes up because many are just holding it waiting for the price to move up. These will result in sudden dumping. How are we going to earn if all of us are doing just the same? So I think it is just better not to hold any coin and do more trading instead.
I think it's better to keep it while waiting for the price to improve, because in recent times there has been internal bitcoin competition so prices continue to decline. But in recent times prices have begun to improve so that the development of bitcoin in the market has received a positive response
