This is a stupid law.  From its inception.

Any of the big movers of cash just use the banks.
It is fricken easy if you can afford a lawyer or two.

You move your cash to Cuba.  Then you hire yourself or someone you want to give money to, to do something.  (Do project X @ $1000/hour)
Or, give yourself a loan.

So, the law is meant to harass and terrorize little people.
And it will lead to confiscation of anything they say is inappropriate.

Things like: you have 1 bitcoin.  Valued at $3,000 when you board the plane.  And when you get there they say its worth $10,100 so, you just broke the law, confiscate everything and send you back.
