Such amount of money is being move in the banking system without issue just that you have to fill those paper works in other for them to ascertain the source of the funds and be sire it complies with international laws and I wonder what the problem would be if you don't have anything to hide.

And even thinking no paper work is need to move that kind of money because is crypto is grossly exaggerated only if he won't pass through exchange site because there your verification will be on the highest level.
