Let's accept the fact nothing last forever in this world there will be the day that bitcoin and the cryptocurrency world will disappear and die if there will be better things that will come up in the future or if supporters, miners have stopped using, buying, and trading cryptocurrency. Bitcoin and crypto will live as long as there will be people who are there to use, support, and fuel the network.
Nothing is eternal in this world and that is a fact. As you said, bitcoin requires support from all parties to become a valuable asset and is also useful as both a payment system and a tradable asset. I assume that bitcoin will continue to exist even though no one will ever use it. But what is worthless is useless and will be left behind. Until now, there were no signs that bitcoin would become useless and the community continued to grow over time.
Bitcoin has been shown to withstand a pandemic is one of the many reasons it is believed to continue to be used for a longer time. Without any technical failures, I think Bitcoin will continue to be a very valuable asset regardless of the world situation. Politics, economics and things that have a big impact on the world economy will be factors that affect the price of bitcoin.
