Bitcoin is entirely different from oil. Bitcoin can never be zero or below. The only scenario where i can see bitcoin going to zero is people stop using bitcoins and there is no demand (maybe an issue is triggered in the blockchain). If that happens, bitcoin will be finished. Don't expect bitcoin to go to zero and bounce back from there. It will be dead forever if it goes to zero in value.
Do you remember about bitcoin innovation?
Bitcoin offers many benefits for all users and bitcoin is not solely abount trading and in my opinion there are some things that make the price of bitcoin will not be zero, is:
Global accessibility, Every bitcoin user will benefit from it, especially related to global accessibility. We can accept and send bitcoin anywhere and anytime with just one click.
Cost efficiency, We do not need to think about transaction costs that are too much even though transactions are carried out between countries.
In my opinion all innovations from bitcoin strongly support that prices will not be zero. Adobsi which continues to increase will allow it to continue to exist and continue to be used primarily by the bitcoin community itself.
