Bitcoin does not work because people do not trust to buy things with bitcoin. I have a site running now for 5 months selling precious metals, made plenty of sales with credit card, bank transfer, no problems but not a single bitcoin purchase!
What is the point in bitcoin again?
Bitcoiners can send any amount of bitcoin around the world in 10 minutes for a few cents. Tried sending gold threw the post ? Haha.
Private keys can be encrypted with a password, so unlinke gold, Bitcoin is much more resistant against theft.
You understand now ? Since Bitcoin overpowers and disrupts gold in every aspect, why would Bitcoiners buy gold ??
Gold is bought because it has been successfully used as a medium of trade through thousands of years. Bitcoin, in perspective, is just a relatively new experiment.
