EDIT: I'm shutting this topic down. I gave up on keeping track of this ages ago, because it just got too depressing for me and besides I couldn't keep up.
People keep sending me messages asking me to take things off the list insisting that so-and-so isn't dead. If you have successfully revived something, congratulations. But this list is now a historical artifact and I'm not keeping it up to date. Nor am I interested in debating what "dead" means in terms of a block chain coin.
Usually it turns out that they are just reusing the name of so-and-so, which is, yes, still dead. Alternatively, they may have a live block chain of so-and-so which still does not appear on the significant exchanges, or which has still such an insignificant market value, that it is, yes, still dead. And these points are just too tedious to debate and I don't even have time to research them all.
There are also messages I find particularly depressing, or which make me angry, and those are from people who are digging zombie so-and-so up for one more lurch around the gravestone, in a necromantic version of a pump and dump scam, using the fact that "so-and-so has been around a long time" to reassure their prospective bagholders.
Anyway: To everybody reading this list: These coins were what I considered dead, at the time I was maintaining the list. Some of them may not have stayed dead, and that's okay. Some of them may be in the hands of people now pretending they aren't dead, as part of a scam, and that's not okay. I'm not going to help you decide which.
To everybody who has something that appears on this list and believes it isn't dead: That's fine. Maybe it isn't. I am not updating the list, so consider this as information about its history, rather than information about its present.
The objective of this thread is to keep track of the death of altcoins. My plan is to study how and why they die. I'll be updating the entries, and posting more complete notes next to each of these as I investigate and learn things. Any contributions of information or pointers to it will be welcomed.
In some cases I will want to find and download a copy of their blockchain if it's still available -- often some blockchain archaeology will offer insights into how it all came apart (or how some scammer profited by it).
For purposes of this discussion, I'm going to count any coin as DEAD, even if its blockchain is still running, when it is currently either delisted from all exchanges, or when it ought to have been because its total market capitalization has wandered south of US$5000.
Nothing will be taken off this list until or unless it claws its way out of the grave by having its market capitalization climb over US$5000 and stay there for 90 days.
If a coin has never been on an exchange yet, I'm not going to bother counting it as dead, unless it gets listed on an exchange while its market capitalization is still less than US$5,000 (which I'll count as a stillbirth). In fact I'm tempted to list *EVERY* new launch as a dead coin until 90 days of continuous market cap above US$5000.
I'm using coinmarketcap.com for coins that are still on some exchange somewhere, and counting all coins not currently traded on some exchange as having zero market capitalization.
So, here's a list of dead cryptocurrencies, in more or less alphabetical order. There are probably a lot more that I don't know about yet, and the cryptocurrencies on this list will eventually be joined by dozens or hundreds more as the market does its magic. Also, some of these may manage, for a while, to crawl around outside of their graves - though as with other dead things, smart money would be betting against it. In many cases I don't even know the trading symbol that something used; additions and corrections are welcome.
2chcoin(2ch)
2chcoin was apparently a Russian clone of Quark, with a very fast block reward halving time. It was announced on Bitcointalk on 6 Jan 2014 by 'Rocketron' (a new user whose email/ID information is hidden) with a giveaway thread. On 9 January 'bazilko' announced a simple lottery game using 2chcoin. This game ran, apparently picking a winner every hour, for at least ten days. 2chcoin was picked up by at least 3 exchanges. As far as I can tell the developer never made any modifications to it whatsoever, and never communicated with anyone about it in English. I can't read the Russian threads, so it may look from the other side of the language barrier like the dev was more involved .
66coin (66)
66coin was launched Jan 26 2014 by 'menzo' (email/ID hidden). It was a scrypt coin with 66-second block time and a .000066 coin per block reward. Total coin supply was supposed to be 66 coins. It used a 'runway' launch, with the first 666 blocks worth 1/100 the nominal block reward (in order to let people get their mining settings sorted out before they started missing significant rewards). Launch went fairly smoothly, but there was a failure starting around 12 Feb when hashing power went up and most users couldn't get wallets to sync. 'pikimunga' took the initiative to rescue the coin starting on 17 February, first fixing the sync issue by getting people onto the same chain, then putting up a mining pool and organizing an effort to bribe exchanges to list the coin. Pikimunga apparently continued as a dev in partnership with menzo. There were a couple of hard forks but they seemed to go fairly smoothly. Despite these efforts, the price has declined to the point where the coin appears to be irrelevant.

Acros(ACRO)
AeroCoin(?)
in the 2013 timeframe, apparently a pure IPO scam. The scammer accepted BTC in payment for AeroCoins, and then disappeared with the BTC. Not to be confused with a different Aerocoin(AERO) which appeared in early July 2014.
Aircoin(AIR)
apparently there are at least two different things both named aircoin and both trading with the symbol AIR. coinmarketcap is tracking one and cryptocoinrank is tracking the other. One is effectively dead and the other apparently alive as of 12 July 2014. It is not clear which the investigation below describes, nor whether it includes features of both.
launched 20 Feb 2014, Aircoin was launched by 'aircoin' (a new account with hidden ID/email) and featured a complicated scheme to adjust the block rewards in response to the exchange rate in order to target a gradually rising exchange rate. There were MANY things wrong with this cryptocurrency on launch, but people treated it as though it were serious. They never explained how the feedback from exchange rate to block reward was supposed to work; in fact it did not. Block reward adjustments were implemented by releasing a new version of the client and hard-forking rather than in an automatic way. The coin supply was theoretically limited to a billion coins. The reward halving time was supposed to be about once per five years, but that didn't make sense given the mining reward adjustments to target an exchange rate. Seriously, the math didn't work, and nobody called them on it! Also there was an initial premine of 2.5 million coins, and the 'nominal' block reward and block rate made that about 30 months worth of regular mining rewards - one of the larger premines I've ever seen, although when expressed as a percentage it was only 0.25%. Anyway, it was claimed that the mining rewards ought to last for something between 100 and 1000 years given the dynamic adjustments. The launch was botched, with source unavailable and the node server behind a NAT address where nobody else could get at it.
Alcohoin(ALC)
Alcohoin was a scrypt coin with a 30million coin total coin supply, 1-minute blocks and a 150-coin block reward. It was launched 21 Jan 2014 by 'Alcohoin', a newbie account with hidden id/email information. The 1% premine amounted to about 33 hours of block rewards at the nominal block rate. There was a giveaway for high scores at a drinking-themed flash game. The developer apparently abandoned the coin after selling the premine.
Alicoin(ALI)
AlienCoin(ALN)
Launched January 9 2014. 30s blocks, 40-coin block award. 'Alien420' made the announcement, 'Hendo420' is a dev. Both accounts have ID hidden. Appears to be largely a clone of 42coin - in fact the initial client attempted to use the same RPC port so you couldn't have both at once. Launch announcement claimed there was a 1% premine and a 200M coin total money supply. On Jan 11, block explorer revealed a 200M coin premine and source code revealed a 400M coin total money supply. On Jan 12, the existing blockchain was abandoned and aliencoin was relaunched with a 2M coin premine and a 200M coin money supply. Arrived at an exchange March 15 2014 when its market capitalization was about $1000. Market cap most recently seen on 16 June 2014 was $4046

AmericanCoin(AMC)
Coingen was used to created something called 'americancoin' but this launched before coingen.io was registered so it may not be the same thing. The first 6500 blocks were mined before the cryptocurrency was announced. Also, the wallets of this litecoin clone kept trying to connect to the litecoin network, with the predictable results; the blockchain was in a perpetual state of fork.

Apecoin(APE)
Announced by 'apecoin' (a new account with hidden ID infomation) on bitcointalk on 18 December 2013 - apparently a couple of days after it was announced on Reddit. About 3 and a half days worth of coins were gone before the bitcointalk announcement happened, and it's not clear how many of these were a premine held by the developer. It was a scrypt coin with one minute blocks. The initial announcement claimed a 6.84B total coin supply and a 'sinusoidally decaying' block reward, though neither was implemented; the source code revealed an unlimited coin supply and a block reward of 10K coins per block. Ten days later there was a hard fork to implement these features. The coin was reannounced on March 14. The relaunch earned lots of praise posts from obvious sockpuppet accounts, which was kind of humorous.

BatCoin(BAT)
Batcoin was released on Jan 6 2014. It had an anonymous developer (HUGE WARNING SIGN) and a 2% premine. Also the community took up a collection to bribe an exchange in order to get Batcoin traded. Its developer was anonymous so this information cannot be verified, but it is claimed that he was attacked during the night of April 3rd-4th in his home and hospitalized by an assailant intent on stealing the premined coins. If that's true, then clearly he was not anonymous to the assailant. If that's false, then he made a small but respectable profit on the premine. Either way, he dropped the development and support of Batcoin like a hot rock.

BELA was a scrypt altcoin launched January 29 2014 by 'twoturtles' (whose ID/Email information is hidden). It had 30s blocks, 50-coin block reward, and a premine that amounted to about 20 hours of coins at its nominal rates. Its creator claimed that its purpose was to benefit children globally, be donated to charities involved in childrens' welfare, etc. It is somewhat remarkable for its extended client/wallet software, which included such additional services as block explorer, news feed, network statistics, multiple pool status, and trading statistics. I can't find any real reason why it died. Although I don't think something like money can have any agenda beyond whatever people choose to use it for, this looks like it had a fair launch, real development work invested, and valuable innovation, and died anyway.

Coiledcoin()
Launched by 'makomk' (id/email hidden) on Jan 5 2012. It extended the scripting language available in Bitcoin with OP_EVAL, which allowed all sorts of interesting innovative new kinds of contracts/scripts and might have also opened it up to all sorts of interesting innovative new kinds of Denial-of-Service attacks had it lasted long enough for such attacks to be mounted. It was launched as merge-mined with Bitcoin, however, and there are a couple of different ways to do merged mining. Without going into cryptographic details, the way Coiledcoin did merged mining was vulnerable to a particular type of 51% attack, which could be launched by any miner mining Bitcoin provided that not very many other Bitcoin miners were participating in the merged mining of the merge-mined chain. LukeJr, who operates the Eligius mining pool, launched that attack, producing Coiledcoin blocks containing no transactions while monopolizing the production of Coiledcoin blocks. In order to do this, the Eligius Pool used the hashing power of many miners who did not know that the attack was being launched or that their hashing power was contributed to it. As far as the miners knew they were just mining Bitcoin. And in fact, the hashing power they contributed was also used for mining Bitcoin; none of the miners received less Bitcoin than they otherwise would have as a result of their hash power being used to attack Coiledcoin.

Their reward halving was at intervals of nominally 180 days. After a smooth launch, they couldn't get listed on Bittrex because bittrex objected to the drug reference in the name. They were listed on allcrypt, but the price collapsed and miners abandoned the coin.

Created 7 Jan 2014 by 'Mogui', a newbie account with hidden ID/email information. Etoken achieved a market cap of US$418K on Jan 17.
http://bitcointalk.org/index.php?topic=403597.0 https://bitcointalk.org/index.php?topic=436750.0 Mogui outlined a 'rare' coin with 1 reward per block, but used a 'fancy' reward schedule with bonus blocks. There was an x2 bonus for the first 20K blocks, an x200 bonus on any block that was zero modulo 1000, and an x2500 bonus on any block that was zero modulo 10000. Now, for those who aren't thinking deviously enough or haven't realized the implications of all those bonuses applying at the same time, that means that the ten thousandth and twenty thousandth block paid a cool million coins each. So much for the 'rare' coin. People who did figure this out (or who had known it in advance) piled on an acre of hashing power in a scramble to get the ten thousandth block, and then abandoned it once that block was mined. This left the difficulty impossibly high and they had to hard fork the block chain in order to get it started again. At about this point the original developer (who may or may not have mined the million-coin block) abandoned the project. Those left amongst the wreckage restarted the blockchain and ran it for a while, but failed to excise the 'extra' coins from the blockchain, and they were sold on exchanges.

HongKongCoin(HKC)
Launched by 'HongKongCoin' (a newbie account with hidden ID/email information) on March 16 2014.
https://bitcointalk.org/index.php?topic=518669.0 HongKongCoin was a SHA256 coin with 6K coins per block, 60-second block times, and a block reward halving every 50K blocks (every 35 days). 2.5% (1.7 days of coin generation at nominal rates) of the coin supply was premined "to be given away to the people of Hong Kong" and a faucet was set up, but the security was very bad and several people demonstrated the ability to get dozens or hundreds of rewards from it. The rewards in turn were so large that the HKC would run out if 2% of Hong Kong's population got 1 reward each. Here is a thread about some of its problems:
https://bitcointalk.org/index.php?topic=523292.0 In addition to its regular reward schedule, additional "bonus" blocks were added with half-million coin bounties at blocks 40K and 50K. Once these were mined, 'HongKongCoin' abandoned development. A week later the coin was trading at 1 satoshi. A week after that, it was delisted from all exchanges as HongKetoCoin launched in its place.

Something named "Lovecoin" was created via Coingen. As with most coingen coins, there are people who claim this isn't the one that was made via coingen. It might be, or it might not. LOVE was a Scrypt PoW/PoS hybrid coin launched March 30 by 'Lovecoinproject' (a newbie account with hidden email/ID info) that distributed 3 Million coins in an IPO sold by the developer, and reserved another 1 Million coins for the developer. This premined amount corresponds to about 1.5 months of coin production at nominal rates. After the IPO coins were sold to investors and the premine sold on exchanges, the developer abandoned the project. A 'relaunch' with a new dev ('Johnny Non,' whose email/id information is also hidden) was announced on 19 May 2014. The relaunch will apparently be proof-of-stake only.

The launch was smooth and the software apparently worked fine, but the dev, for whatever reason, was never heard from again after launching the coin.

Muniti(MUN)
Muniti is launched March 29 2014. It went on exchanges within days, before its market cap had risen above the level of being a dead coin. The launcher is 'radi324' who, for a refreshing change of pace, does NOT have his email address hidden. The intent is to introduce cryptocurrency to the nation of Malta and to promote Maltese tourism. The developers are apparently actually IN Malta, which is another refreshing change of pace for people who introduce country coins. A 32% premine is reserved for the distribution. Radi324 claims that nearly all of this money will be distributed door-to-door to the Maltese people, with 1% being reserved for a promotional charity donation at a traditional event right after Christmas. Meanwhile they've been actively promoting the coin in Malta, and there is evidence that they're getting active coverage by local media and recruiting volunteers for their door-to-door paper wallet distribution. It is unfortunate that they went for exchanges so quickly, before there was any market capitalization to distinguish them from the thousands of dead coins; I sincerely hope to be taking this off of the list in a bit over 90 days.

(information thanks to 'galaxy') - Claimed sending out a mailer that said "free money" to people in Silicon Valley would spark mass adoption. The pitch was that someone influential would get their junkmail invitation to receive 600 worthless coins, then head right to their computer and start downloading the wallet from some website that would be completely foreign to them. Then said person would say WOW, Im going to talk to my friends and get this thing going. Not a joke. The early investors/miners, dev, and his sockpuppets were dead serious.

Singularity(SING)
Skeincoin(SKC)
Launched Nov 1 2013, by 'Red Kendra' (a newbie account with no ID/email information) Skeincoin was a coin with 32-coin block reward and a 2-minute block time. The Proof-of-work was a two-round hash, with the first round using the Skein hashing algorithm and the second round using SHA-2. Because there are no ASICs that do Skein, that made Skein the limiting factor in proof-of-work. Accordingly, many coins were donated to Botnet operators. Launch was apparently smooth.

UniteCoin(UNI)
Unitecoin was a scrypt coin retargeting every 60 blocks, awarding 50 coins per block, with 2-minute block times. It launched halving the block reward every 840000 blocks. The announcement made on Bitcointalk at
https://bitcointalk.org/index.php?topic=372707.0 says every 84000 which would have been about 3 months, but the source code at
https://github.com/unitecoin-org/Unitecoin/blob/master/src/main.cpp says 840000 which is about 3 years. Its nominal block time was two minutes according to the source.
It was released initially on December 1, 2013 with an announcement on cryptocointalk, and was not announced on bitcointalk
https://bitcointalk.org/index.php?topic=372707.0 until 16 December. About 3 weeks worth of coins at nominal block rates were already gone by the time it was announced here, so Unitecoin was considered by some to have been premined. The blockchain shows that the first 3 thousand blocks or so - about a week's worth at nominal rates - was mined very fast, but that's likely due to ordinary launching at low difficulty.
Trading in Unitecoin appears to have started at a market cap of $196 on April 16 2014 and ended at a market cap of $28 on May 27 2014. During that brief time it had four peaks in market cap, to US$591, $1136, $1141, and $635. Between these peaks, it crashed to $38, $75, and $62. The trading history is truly remarkable in that it appears to have gone through FOUR separate pump-and-dumps, each capable of transferring up to 90% of the bagholders' remaining money into the pockets of the dumpers. This doesn't usually happen, if only because after one or two pumps all the sufficiently gullible bagholders are broke.
