The list of dead coins is increasing and many of them are dead for good reasons. https://deadcoins.com/

There is even a project that "buys" failed coins.

But sometimes in history there is an idea that was premature and the world was not ready for it yet.

Should any dead alt coin be revived ? Or should they be left to "rest in peace" ?

Yes, it is possible. But only one possibility is that it is being speculated or there is a whale to invest, then it is possible to revive. There are no other possibilities besides this.

a coin doesn't just die for no reason. you said it yourself "they died for a good reason" then you contradict it by saying "world was not ready for them"!
basically if a coin was any good then it wouldn't have died in first place because there would at least be 1 person in the world that would have seen that "goodness" and kept the coin.
most of the coins that have died are poor copies of another coin so there is no reason for them to come back. also the problem that caused their death has not gone away. it still is there and eve if someone revives them, they would just die again.

and why would anyone want to revive a dead coin when there is an alternative option? you can simply start the same coin from scratch and fix the issues that it had to try again.

The cryptocurrency space is an ECOSYSTEM and only the fittest of the fittest survive. For whatever reason a coin dies it is an indication that it was either poorly engineered "genetically" (faulty code) or poorly built "physiologically" (design, ease of use and usefulness). Dead coins simply can't compete in the crypto space and should remain dead  and burried to free up the crypto space for worthy projects to thrive.

So far there are 897 coins & tokens listed as dead, in a year time that number will likely double because a lot of projects are presently on life support despite the huge money they claim to raise from ICO.
Who is going to revive them and for what reason?

the "dead coins" didn't die in an accident like a car accident to take their lives suddenly and unexpectedly. they died because they were useless or in some cases they died because they had some serious bugs that were unsolvable. otherwise even the shittiest shitcoins stay alive as long as there is someone trading them. for example you ca go on Yobit and see at least a couple of hundreds of them being traded there that don't even have a blockchain anymore.

This is a dead coin. If you have such coins about them you just need to forget. There are isolated cases when the coin was recovered. I have dead coins, but to someone to sell them for pennies, let them lie better. And then suddenly they get excited.

Some made fortune on seemingly "dead coins" who had another heart beat. Are they worth reviving? As long as there are new and relevant developments.

This is not good to see, there is a whole lot of dead coins already and with the current market condition, a lot more coins will be dead too, but I believe any project that has a great prosper will not be dead, I see most of those project on the list has no real use case and some doesn't require blockchain
