I can't see a situation right now to see bitcoin die because instead of dying it will be on a progressive growth where each year there's a growth.
But let's give an example, if ever the whole world will make a total ban for bitcoin, the market will be keep on going but there is a chance that many investors and holders will let go.
And that will start bitcoin to be dead. But that's far to happen if we will think about it.
Exactly Bitcoin has been established (7+yrs), has vested interests globally (diverse places like Phillippines, Japan, Russia, Spain, China, USA, India), has an immutable transparent ledger, crypto-secured, decentralized system of checks with small blocks.
It has destroyed spam attacks, daily hack attempts at some of the smartest hackers globally, and government attempts of bans.
It has emerged as, (although volatile) the ultimate store of value.
If curious, i detail the dynamics & reasons for this at this post:

Many of us are going to do something to make it keep longer and will make the market and bitcoin itself to become alive.
A lot of things has passed with bitcoin already and I believe that it made it even stronger now.
