Ignoring bitcoins, how would you smuggle that much gold?
What scenario are you thinking? The one that got those guys caught (from S.Korea to Japan,) some other, or in general?
My first thought would to be to actually make it into real jewelry. I don't know that women wearing jewelry won't get stopped and charged a tariff for wearing it into the country though, so that may be out.
The situation these guys were in: Trying to transport gold from S.Korea to Japan.
I was thinking jewelry works as well, but would require either a lot of trips or a Mr. T styling. If you don't have to put your stuff through an x-ray scanner, filling laptop with gold would work. Otherwise, you might just want to fill the hard drive with gold if that isn't normally penetrated with x-rays.
Some other tricks: melt the coins into the shape of dollar coins, and coat with a material that makes it look normal. You could fill the inside of crutches with gold, or the tubing for a baby stroller (you will need to borrow a baby for this one). Basically anything where metal is expected and can be replaced with gold and concealed would work.
In the end, it makes a good case for bitcoins.
I remember when my sister was in africa in the peace corps, and we wanted to send her cash. We had to conceal it in various objects to prevent customs from taking it.
