Everyone on the planet thinks gold=money.
A handful of libtards and techno geeks think Bitcoin=money.
The rest of the world thinks Bitcoin=crime.
You tell me, is gold better than Bitcoin? If you were stuck in a foreign country would you rather be carrying a paper wallet worth $15k or one pound of gold worth $15k.
Here's my choice:

The fact is also that you are partly right but if you think about security matters, the bitcoin is a lot safer and can also be converted at any time with gold this is not the point at all.
Another thing is that I rather have a paper wallet with 15k than gold because if I get robbed in a foreign country I would be fucked for life.
Personally, trying to draw a comparison between using gold or Bitcoin in a foreign country is stupid to say the very least, and completely unpractical when you consider what you're talking about. It's basically "hey look I have this hard-to-use currency worth $15,000 that I can exchange in small amounts" and "hey I have this easy-to-use hard-to-break-down brick worth $15,000 I have to exchange all at once".
It's not simple like that.
