There is no point to any of the alt-coins because they provide no value other than a means to make the owners of the exchanges rich and/or a means for late-comers to be able to get some bitcoins in a faster and easier fashion.
Unless an alt-coin is accepted for goods and services it has no value and cannot have value.
Exactly and right now bitcoin is only just on the verge of becoming commonly accepted, it still has a long way to go. But these random other coins don't.
