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.

LoveCoin(LOVE)
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.

launched Jan 24 2014 by 'Blazr', a junior member account with email/ID hidden. Named for the plot device in the 'Dune' series by Frank Herbert. Released on the scificointalk forum 30 minutes before release on bitcointalk, which led to some talk of an 'instamine', although it looks like even people who first saw it on bitcointalk were able to get in on some of the first 400 blocks or so. 18 coins per block, 4 minute block intervals, block halving every 20K blocks. 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.

It was an n-factor scrypt coin with a halving time of 60 days. There was a premine that amounted to about two days of coin production at nominal rates, which was sold for 50BTC in an IPO. (1 BTC per 28.8 RT2). Rotocoin was observed on May 10 2014 to be trading at US$0.18 per coin, with market cap under $5K, and on 17 may at 0.092 per coin with market cap US$2552.

SiliconValleyCoin(XSV)
(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. The thread is a classic example of a pump and dump attempt.

Silvio Berluscioni is a very wealthy Italian Businessman and Politician.

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://bitcointalksearch.org/topic/ann-unitecoin-uni-372707 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://bitcointalksearch.org/topic/ann-unitecoin-uni-372707 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.
