Lol, but illegal to whose perspective? I understand that the Chinese government can sell 100 tons of gold, and force a drop of $50 in spot, then buy the 100 tons back and raise the price by $50. Personally, I feel that market manipulation happens a LOT out there, as we all are on the sidelines betting with our paltry sums. I see Silver having the same fate, with Gov’ts jumping in, but also big Tech trying to capture industrial supply. Buy/sell inventories to influence / suppress price to gain inventory advantage.
