In my opinion all this coins aren't so good for holding for a lonng term. Just should to buy such top 5 or 10 coins and hold them.
I do prefer to tell people that always support those coins that are on the top. But not everything on the top are good enough for me, I've got my standards so that's why I'm telling it. Some of those coins on the top are manipulated so I don't think its always a wise choice.
