I still think that it would take quite a bit of time, effort (and maybe even a bit costly) to put that much ($191,000) into bitcoin (through local bitcoins or some other kind of direct (non-bank) means and then the same getting it into bitcoin, then the volatility risk and then getting it out of bitcoin... whoaza..
Not as big of a problem if you are putting that amount into bitcoin over a year and then also taking time (maybe over a year) to slowly cash it out, too?
Ultimately, I agree that putting that value into bitcoin seems a whole hell-of-a lot better for the purpose of avoiding those kinds of physical cash carrying issues (controls) than attempting to carry through an airport.
