In my opinion, Bitcoin is more useful than gold, as a transfer of value. Each Bitcoin is guaranteed to be real, whereas gold must be tested and weighed first. Bitcoin is easier to secure, and avoid seizure. You can actually store an unlimited amount in your brain. Try to grab that at a border crossing, or airport.

Gold has a proven history, but currently suffers from a paper market manipulation. Gold is so hard to move around in a market or in real life, that people throughout history decided to trade it for paper willingly. What good is gold if no one (%wise) actually wants to go through the trouble of looking after it?
