This is 1/2 Mil dollar in a normal briefcase. thank too $100 it is not a lot of space and that can transfer very easily between people. You can move that daily and no one will even think strange as all they see is a brief case. But do that in crypto and you are in trouble.
I'm telling you it is riskier to move half a million dollar in a price than to move it in Zcash. Alot of things may go wrong here moving that kind of physical cash what of if one of your team sold you out but I can move to UK now and I will still have my half a million with almost know risk once there is an internet access
