A lot of altcoins are showing red but that does not mean they they are dying coins the price could be higher back then and it is now that their price is going down because of Bitcoin increase value and beside these alcoins are always bouncing back every now and then.
You are right, the price of a coin isn't a good health indice, community activity and Dev responce time are !
There is a thread listing dead coins, although the last post in it was on December 05, 2015. The coins listed in its OP would make a good foundation to build on if you want to include truly dead coins rather than only "ded" coins that still have moving blockchains. All the coins in that thread's OP are in the cemetery.
https://bitcointalk.org/index.php?topic=588413.0That's a good idea too, it will save a lot of time.
This is also a good idea to post what is an altcoin that is
alive or promising coin. Mostly altcoins are going dumped
because of bitcoin price is increasing. I dont know if LTC
coins still be back to its high price before, eth, doge coins,
lets observe this coins.
You know, LTC is here since a long time, its price doesn't really have a sence as long as the foundation exists to back it up.
All in all, i have just one question, when will we start ?
