My Father in law is an attorney. They excel at finding that kind of stuff. You could only move currency in small amounts over a period of time.
Hmm.... so you are saying that people should be planning for their divorce at least 1 year in advance.

No probs for me. More than half of my net wealth is stored in Bitcoins. And know what? My wife (or my other family members) don't even know what Bitcoin is.

If you want to hide it yes, a lot of marriages end so quickly that it would be impossible to do it.
I am divesting from fiat as quickly as I can as well. My wife knows about my bit coin but she doesn't know how much I have.
