What to do with unused coax cable? Cap it?

I was recently sent a new XFinity 4K TV box that uses streaming wifi instead of the coax cable. What do I do with the old cable? i don't want to remove it entirely in case I use it again down the road but does it need to be capped for safety when not connected to anything?
