Hey guys. Don't feed the trolls. I'll come by and delete them eventually.

And anyway, a little trolling is good. It gives you something to talk about. It shows that Uno is on the radar and that this is the thread to be in.
So the question about what would stop someone from creating their own rare coin?
Absolutely nothing. Many, many have already tried and failed. The community that would be interested in these kind of rare/fair characteristics has already coalesced around Uno.
The list is huge: arkenstone, vikingcoin, lemurcoin, 84, 66, 42, 21, macrocoin, sync, and many, many others.... all failed to get a critical mass. There can only be one true rare/fair coin, and Uno already has that market.
I believe that Uno's strength is that its value is not tied in any way to a complex project that some unknown developer has to build tomorrow. Its value is already present today. It's as pure a store-of-value play as you'll ever find in crypto. That has helped it hold it's position while a thousands other currencies have slid past.
If it's going to be pegged to anything, it should probably be bitcoin, but the peg would have to be something like 70:1 btc:uno because of Uno's rarity. Sidechains will create some interesting opportunities in crypto very soon. As sidechain innovation becomes clearer, I anticipate Uno reaping benefit from it, although at this moment I'm not sure exactly how that may occur. I buy it today for it's current value; if there is upside tomorrow from adjunct crypto innovation, then that's all gravy.
