I'm concerned that there are so many "alt-coins" that are just complete silliness.  Why mine coins that are just nonsense?  Bitcoin has established itself at completely legitimate in people's eyes.  Even a danger, in other people's eyes!  Litecoin is #2.  But, beyond that... I mean, I'm buying Devcoins and buying/mining Dogecoins, but how does a "coin" gain any legitimate traction?  I mean, who wants to trade Sexcoins and Cryptogenic Bullion and any other number of "coins" that seem to pop up on a weekly basis.  Why?

Is this something akin to collecting baseball cards?  How does something like Mastercoin, which just popped up a few days ago, I think, get worth over $100 so easily?  What gave it such a reputation to be worth that much?  Who stands behind it?  Why should I want it?  Will it even BE here, to trade, months from now?

What gives one coin more USD value over another?  Why are people creating new coins all over the place?  Why are people even trading them?

Isn't this all supposed to be about creating/validating a legitimate crypto-currency; alternative to the US dollar or other government-based currency?  I mean, Dogecoins are cute and potentially worth more than fractions of a penny, but people are creating things like mousecoins and catcoin and hotcoin, etc... it's getting ridiculous!

Maybe what I'm trying to figure out is...

What is the ultimate purpose of creating coins with a bazillion different names, many worth a few cents, some worth dollars, yet all seemingly similar (SHA256 or Scrypt-based) in their design?  Why are people creating them and what is the ultimate value IN them?  Unless people will trade real-world items for these multitudinous currencies with such diverse (and some crazy/silly/nonsensical) names, and the trade value is legitimate in the seller's/buyer's eyes, what is the point?

I mean, I have 100,000 DOGE now.  What can I buy with that?  If DOGE ever hits $1.00 USD, I could buy a real-world house... but at it's current value (0.00059 USD), could I buy something worth vastly more than $59 USD?  Do crypto-currencies hold value in their own realm, and not just in their representative real-world dollar value?  Is this not the goal?

Is not the creation of a bazillion different "currencies", with funny, silly and/or even ridiculous names, just a pointless venture?  At worst, is it actually destructive to the efforts of actually creating a legitimate alternative crypto currency?

Just trying to make sense of all this "coin creation" going on.
