It is still alive. But it will be dead sooner or later.
Just like fiat.
Bitcoin is currency of future, will not die. In fact will continue to grow and more and more people who use bitcoin in transacting.
Yes bitcoin has possibility for being the future currency and it will not die because of the continuous support of the community and also the good development for bitcoin but bitcoin can be also dead if there will be a worst case scenario like the miners migrate to another coin and they just left bitcoin and its network will not have a support until it collapse and bitcoin transactions will be stuck and it will make the bitcoin dead.
in fact bitcoin is already our future currency, because the new generation are giving preference to online trading and business they are also using online shopping therefore they are giving preference to bitcoin as bitcoin is their first choice, and that is the reason that we can say that bitcoin is our future currency.
