I dealt with many Chinese investors coming out of Hong Kong, China, Singapore and Indonesia etc... When one lady opened a restaurant in California, I was her friend. She asked me to introduce her to my stock broker.
When she asked him to purchase stocks for her account, he said OK.
She then pulled out a big cloth bag full of gold pandas and used it to pay for the stocks. I kid you not. Hard cold gold. I dealt with South African gold businesses before. Roll your gold.
My advice is to buy a gold/silver platinum/palladium mine, or two.
I had a similar experience in the late eighties/early nineties.
A South African surfer of my acquaintance came to Hawaii to surf the North Shore every winter. Oddly, every year he brought an unusually heavy surfboard with him which he immediately ditched in favor of a locally built big wave board.
His broken up SA board would appear in the dumpster shortly after his arrival from Cape Town and he never took his Hawaiian board home with him.
