Everything in this world have ending or shall we say has its duration. in my own opinion bitcoin is not going to die if ever it would die but it takes too many years i guess, maybe in our lifetime or even in many decades. Bitcoin spreaded allready and have already reached high market cap and everyday in became more popular.
Bitcoin may evolve further and might be different from what it is today in far future.
But bitcoin death is not going to happen as long as we human needs money
well you never know, but even if btc dies, blockchain will live on. of that i'm sure.
