I do not see the point in buying and holding cheap altcoins in the hope that they will become much more expensive. Bought, 2-3 days and sold, that's my strategy.
If this is working for you then it is good. Also buying any of the cheaper coins and that too for long term, agree that it will become useless coin and will not be worth anything in future. So that should be avoided. But if someone can spot a very good opportunity at early stage in the new coins then it can all be worth it. Though it depends on everyone what startegy they plan to adopt it.
