LOL...dude, how you skip Litecoin and include Ultracoin and Potcoin on your list of coins that will "make it" is beyond me. Litecoin is so far ahead of all these alt-coins derived from it, they have no hope of ever catching it. And yes, Dogecoin will stand a chance long-term as a virtually worthless token that is the money equivalent of a "like" on social media.

Potcoin's problem is the same problem 99.9% of the other alt-coins have - they don't do anything better than the "big two" and therefore, they're superfluous marketing exercises. I mined POT for a while, recently sold my hoard when the dev team clearly disintegrated and things started falling apart.
