Hello!
I'm a Canadian miner, and of the coins I've been following closest, I have to say I'm most impressed/intrigued by:
Darkcoin - Very interesting, technically. Innovative difficulty adjustments and algorithm. CPU and GPU minable. The idea of anonymity in transactions isn't just something that will be leveraged by "shady" people. It's a legitimate and unique feature that may appeal to a wide market. Great community. I like this coin a lot.
Noblecoin - One of the most impressive communities in the Altcoin world today. I love the approach these folks took of trying to grow the community and find real world uses for the coin BEFORE seeking out exchanges in an effort to pump the coin's value. This may not trade at a high value right now, but I think this one has real legs. This one deserves success.
Mintcoin - Tremendous concept for a POS coin launch, and it has gone fairly well so far. Community is there, and active. I like the model, but it has flaws. Exchange wallets can generate large quantities of coins on their own, and this could really hurt the coin's value going forward. If the community stays involved though, this coin has tremendous potential, as the POS seems to be working quite well in terms of transaction time and security so far.
Blackcoin - Very similar to Mintcoin, with a smaller yet more passionate community. BC is doing a lot of things right, but has little real world traction going for it so far. Very young coin, though. Keep an eye on this one.
If any or all of these made the exchange, it would make me very not-sad! :0D
