Lottocoin

Assuming we're going from start of next year to end...

1) FTC (if not, probably won't survive - I see it as a thrive or die kind of situation)
-Bitcoin goes here-
2) LTC
-Or maybe Bitcoin goes here...-
3) Maybe Quark or Anoncoin... I don't know enough about them. Quark seems fairly popular in circles outside my own.
4) I'd guess a fair chance of survival but doubt they'll grow in "market cap": Doge, Peercoin & Primecoin... Namecoin may continue to drag itself along if devs support. Maybe Sexcoin, but I don't follow that sector...
5) Rest, I either know absolutely nothing about or don't see still being traded in a year's time. I seriously doubt more than ~1/3 of poll options will be traded on an exchange at next Christmas.

A lot of this hinges on what happens with BTC in the next year, too. CoinJoin is very appealing, possibly reducing transaction fees, blockchain bloat, and improving privacy.... something else I really, really need to thoroughly read about. CoinJoin and similar improvements on Bitcoin may take away significantly from the practical advantage of LTC/FTC.

Decentralized nature of BTC becoming compromised, I see as a factor, too, especially closer to the end of the year. I don't see mining centralization being much of an issue - moreso node centralization. Regulations are always a concern... still waiting to see where the idea of Smart Property goes (could revolutionize money even moreso than when Bitcoin was released)... interested in seeing where the idea of "coin as a casino" goes... Multi-currency wallets could be a game-changer, possibly greatly increasing interest in altcoins.

Nxt is not an altcoin, but a 2nd generation crypto-currency. It's not build on top of Bitcoin, but has it's completely own source code. Nxt will be the next big thing, so better check it out

+1 ! emunie is going to be huge! for those who haven't heard of it, check out the features:

My bets are on emunie, quark, and devcoin. i will also add zerocoin if/when it is released.

also missing Unobtanium

It baffles me to see so many people taking Doge seriously. I mean the dev even admitted it was all a fun joke. lol

Well personally I am waiting for HobbitCoin. j/k lol

I made 10x ROI in three days with Dogecoin. And I certainly wasn't the only one. Joke or not, its growth has been insane.

I think 1 of the reasons Doge has had success is because of the flood of noobs to the Alt Coin section since the Nov. Bitcoin run up. Right time, right place to launch a funny, cute innocent looking coin.
