I don't know if it will die, but a lot of bitcoins will eventually disappear. Already there are probaly a couple of million locked in wallets that passwords have been lost, and will never see the light of day again. Also, probably some people drop dead without leaving next of kin info about their bitcoins. I wonder how many bitcoins will be out of the system forever by the time all 21 million are mined?
People or member here who are saying that bitcoin is dead its just an competitors they are just an altcoin that can attract people to convert to altcoin instead of staying in bitcoin..
I remember that people said the bitcoin was dead, but it is still very healthy. That could be applied to litecoin as well.
