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.
The greatest "threat" would be from competing digital currencies.
But I think Bitcoin will always be there lurking in the shadows like a behemoth IBM.
Bitcoin will succede or fail based on its own qualities and how its adherents handle thing.
"Competing" currencies, IMHO, have nothing to do with it.
