If the price goes to zero of course there will be panic, I believe if this year the price is $ 1000 then 2024 will be zero and it won't take long, panic will occur and many exchanges will close when the price is $ 1000, and of course altcoins will also end and we must be prepared if this condition occurs.
If the price goes to zero there will be great panic in the cryptocurrency industry. It all depends on the method that will lead the price to zero. The only time that the price will get to zero is if the network is compromised. If there is 51% attack and there is a chance that the price of bitcoin is brought to zero, there will be a big panic and problem.
But if it follows the pattern you insinuated, such that this year it will first get to $1000 and next year it will go to zero. If it follows this method, I bet you that the price will never see zero. As an ordinary investor, if I see the price at $1000, I will try my best to atleast own like 10
BTC. And this is what other ordinary investors will do let alone whales. So, if the price of bitcoin gets that low, the only disadvantage is that it will be highly volatile and manipulative but it will never get to zero.
