Do people trading Gold need more than 7 tx's per second?
(i.e. do you think Bitcoin would really *die* if that was the limit?)
1) For all the gold in the world, traded amongst all the people in the world? Yes
2) It will die because it will be replaced by something without a silly limit. All it takes is that people start doubting the technology, and opening the door to a competitor that is obviously better.
