I just keep laughing. It's unlikely given the problem we have with fiat currency and the problem Bitcoin actually solved, but who knows what will happen tomorrow? Someone may develop something more efficient and dependable than Bitcoin.
Why not only see the current options and choices which are available with us and bitcoin is the only reliable decentralized currency on which every investor can trust and invest in it.
When bitcoin was moving in range from 16,000 to 18,000$, many people were thinking it will dump more towards the 10K level. Some were even of the view that it may reach to zero after hearing so many negative news about FTX and LUNA. But bitcoin did just the opposite that is start to pump again despite all negative vibes around.
This shows that bitcoin value to go to zero is beyond expectation and is almost impossible. Unless there is any loophole found in bitcoin blockchain, bitcoin to zero is just out of question.
