Judging from what we are saying i understand why you think it's immortal, but i don't it is Michael Saylor may think so too that's because he has a lot of Bitcoins. Due to Bitcoin decentralized nature and the large it has gotten from people some may think it is immortal but it's not if it starts loosing relevance, governments regulations can crash it, a lot of factors can make Bitcoin break but for now let’s make use of it
Maybe they can crash the price but not the network though, it's decentralized, as long as there's electricity and internet it will continue to live, now with satellite internet I doubt BTC can be shut down.
It will be like in china where government bans bitcoin with regulation and all but apparently china still has crypto users.
