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.
Yeah I agree with you, everything in this life nothing is eternal. Neither the bitcoin, which may have had the time or duration. hehe
But that does not worry me, because if bitcoin will end I think there will be signs of its own and with these signs I will turn to other currencies

And look at opportunities that can be done now with bitcoin,I think bitcoin it's safe to 10 years to come.
