I realize you (and some here) have a different sort of timescale in mind than most in the cryptoworld is used to, but delay too long and the coin will be perceived as dead. And at that point, it may not matter a whole lot what you do.
What's your definition of a "dead" coin anyway? And who would perceive it as dead?
I think you're still overlooking the point here. The ONLY way this coin would "DIE" was if the internet as we know it died. But then again, I'm sure we would work around that in a record time.
I did say perceived as dead. Technically any coin can live forever so long as the internet exists. As for who would perceive it as dead ... the investors and miners.
And the risk of such perception is a lack of miners, insecure blockchain, exchanges (or one exchange in this case) dropping the coin due to lack of volume, and the price sinking to nothing levels.
