At the moment i think this would also be very illogical to happen, seeing how long it took bitcoin to reach its current state makes me more confident that its value will always grow in time. time.
Some of the fiction stories that I've seen on many movies talk about the future life of people in war, or natural disasters,... and it's also very unlikely to happen like a tragedy right now disaster with the economy causing things like bitcoin to lose the status it created.
natural disasters and wars in the future might happen and there are even some rumors that say there will be an internet apocalypse in the next few years, even so bitcoin will not be erased in the minds of millions of people, even though the internet doesn't exist, we can still transact bitcoin with systems such as SMS.
the volatility of the bitcoin price is its nature, no one will be able to change that but for bitcoins to have no value is impossible, people will not let that happen, they will continue to buy and sell bitcoins.
