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.
I do not see why there i atill illegal mining, when come to think of it, no really owns any land in this world, it is a gift for mankind and we are the only one that makes gold and silver valuable becuase of their peoperties, i think that's my view as a naturalist, but as an investor, both gold and silver are great investments, though the price is somewhat stable compare to bitcoin, both metals can makenour rigs, our processors even run more efficiently, since bith are good conductors of electricity, i guess if you have gold and silver working together with bitcoin, then you can have more earning potential from mining, and also if you invest on them, we can say that you are secured for the future.
