Well for what's it worth I've only ever needed it once. I was moving out of China and wanted to take my money with me. It was really hard to get this done, there are tons of capital restrictions and the banks literally wouldn't help me out.
So I put all my money in the BTC blockchain in China and pulled it out in the EU. The other option was to get it in cash and physically bring it over the border, which I considered riskier.
