Its no surprise that the Chinese are heavily involved in the illegal mining of gold and other precious metals in almost every corner of the globe. But there is rather wisdom because these two precious metals are very stable and very good when there is a global financial crisis.
Yeah it is right that investment is gold and silver is the safest way of investment. Good thing is that, you will have full control on your investment. There will no fear of hacking but the fear of stealing and robbing will be there. Better to buy gold and keep in bank locker. When you need out it and sell in the market. Crypto is opposite of gold and you have no control over your money.
