At this point, I'd say Bitcoin is immortal. Wouldn't you agree? If not, may I ask why?
Your input would be greatly appreciated. Thank you.

As long as the internet exists, I will agree with you, but if we wake up one day and anything that has to do with the internet is shut down, then bitcoin will go down with it. There is no way to communicate with the technology without an internet connection.
Aside from that, Bitcoin being decentralised alone has defeated the challenge of it being controlled and shut down by any centralised entity.
