I imagine that ChinaCoin might actually be popular with the Chinese altcoin community. It is interesting to see coins that are being made for certain communities in particular. This is actually the kind of thing I was expecting to happen. There is a Chinese exchange that recently opened. I would not be surprised to see it appear over there. You might actually be wise spending some time on these coins CoinHoarder.
That is what the Galactic Milieu players were aiming at years ago, with their Britcoin and Canadian Digital Notes and Martian BotCoin and so on.
It just makes no sense for e.g. the Russians or the Chinese or any other nation to boost the value of a potentially-enemy nation's coin, plus where are that nation's players even going to get some already existing nation's coin in the first place?
No, each nation is going to want, if possible, to start its own currency, if only because they want to actually own at least some of the currency they end up using as their national currency.
Actually by the theories of the Milieu players who got me to make their blockchain currencies for them way back when, it also makes no sense to let players from other nations mint your coins. If you do that then maybe you might as well just go ahead and use some other nation's currency in the first place. To the Milieu players the main thing about a currency of your own is the only way anyone else can have any is if they got it from you, or from someone else who got it from you, thus you know you have enough reserves to back it because you wouldn't have given it to anyone free, you would have given it in return for something, and that something will be in your reserves ready to back your outstanding coins.

We'll start seeing more specialized coins and I'm for it. The coins that are deemed useful will survive the market, the rest will become niche. Personally I focus my energy on the coins I support and leave others to their interests. Live and let live.
