Lots of good responses. Here's my list.
Dogecoin. Good community. Valued a little high at the moment I think. Will take a lot of new money to keep the price high, but if any coin can bring in new users, it's doge.
Premine Coin. Good community. Limited supply. Mining for tx fees only. Interesting proof of concept.
Darkcoin. Good branding. Great concept. Hope the pre-alpha works ok.
Vertcoin. Drifting lower in price. Good time to buy soon? Should increase in price when scrypt asics become widely available.
Others worth a look: Riecoin, Huntercoin, Particle.
Interesting, seems like we both have the same list except for premine.
Doge - The first coin i mined and will be holding this till next year wow shibe wow!.
Darkcoin - I believe this will be on par with worldcoin and etc around 8-10M marketcap
Vertcoin - sold mine @ 85 not bad. made around 4 btc @ 1 day solo mining with 32 cores, would rebuy if it attracts more miners.
Riecoin - found 3 blocks in around 5 days solo mining with 32cores. sigh, would have liked moree! This coin is unique and has a lot of potential because of the new algo.
Hunter - THIS WILL BE BIG! this is my new baby.
Particle - love it got heaps. moonmoon is a kind of dev that wants particle to succeed, still waiting for the new wallet though, got a lot of potential too.
Solarcoin - Most professional devs Ive seen in a long time, heaps of PR on different countries and it's developing a unique community that is outside of crypto so mostly non miners and more on environmental supporters, people are turned off because of the massive premine but if you done your research youll see some huge potential on this coin.
Emunie - tried the beta test client and it works really well, love it, 10-30x your investment could be possible.
Ethereum - don't know much, but I would invest heaps when the IPO starts. lol.
Nem - Im part of it hoorah! so ill contribute everything i can to make this coin successful, its still on early stage though but has a lot of potential since its widely distributed and the devs and members are pretty much enthusiastic about it.
