The point here is, if anyone ever find even just a bar of true authentic gold bar, and if you know that the proceeds will be questioned by virtue of (1) your position in the government, or (2) by your status of living (anyway, most probably, politics comes in), think 10 times before putting all that money in the bank at once. Think of the would-be consequences if they hit you with either of those two republic act. I ain't saying that all the money be kept at home. Better put up first a number of legal, good and sound businesses, then after a steady income comes in (say for a year or two), you can then put all that money in the bank. They won't then have any reason to question your source of income.
Better still, have a good business partner...they could be your fall back and a good reason out of trouble.
