oh well this sheds some light to it, but I really would not want to call Bitcoin broken over this lol
Even though it's a little taboo to mention, the truth is: Bitcoin's developer abandoned the project years ago and disappeared into thin air. If he was still around he would be actively evolving the coin and addressing issues like this one in a clever manner. Bitcoin without Satoshi is like Apple without Jobs.
To my understanding, the only coin actively developing a 51% defense is Goldcoin whose developer is actively building upon Satoshi's unfinished work.
i see that you are highly invested in gold. which might explain your incessant need to debunk bitcoin with false information. if you recently watched the movie about steve jobs starring aston kutcher then steve jobs is actually Gavin Andresen.. satoshi is steve wazniak..
watch the movie again. wozniak invented the first generation PC.. then jjobs took over and ... the rest is history.
satoshi started the idea but it is now gavin A and his team that are fully invested ( time and money) into programming and debugging bitcoin. so where do you get to say bitcoin has been abandoned and think that your statement is in anyway true?
you have no clue.. now go back to your gold investments
