Quantum computers? Bugs in the code? Centralized mining?
Is there anything that can't potentially be overcome that is a threat to Bitcoin? Anything I didn't mention?
Thanks in advanced.
Well besides quantum and bugs and centralized mining as you mentioned can't think of anything else other than new competition that supersedes Bitcoin, or death by regulation and legal systems.
Thinking centralized nodes and 50% are around the same concept but if not worth a distinction as well.
