btc never dead
Bitcoin does have an end like all of the things here on earth but it is too early for bitcoin to die, it is just beginning its journey to the bright future with those who are using bitcoin, if OP's asked this kind of question because of the fluctuations then it is just normal, it is normal for the bitcoin's price to have dumps sometimes, since it volatile, there is nothing to be worry about.
As of now bitcoin is alive and kicking.we all know that all things have an ending,like a story book in every story there is always an ending whether a happy ending or not.Though bitcoin prices and value changes every moment depends on the demand,who knows it will be dead sooner or later but I think bitcoin is far beyond dead as of now.
