Oh come on man, you think that Germany directing a foreign country to freeze assets during the lead in to a war is a more likely way for a Jew in Nazi Germany to lose their hidden savings as compared to them trying to smuggle a USB wallet as they get stripped of all their belongings, clothes, and dignity and loaded on a train? Are they gonna hide it in their butthole and hope they don't have to take a dump until they get out of the concentration camp 7 years later and can finally get around to a computer so they can plug it in and access their bitcoins?

Get the fuck out of here.
