Silver market : biggest trap ever ?

I'm trying to learn a bit about the silver market. And the first thing that caught my attention is the fact that the silver market is considered heavily manipulated. Indeed, more than 90% of investors only buy paper silver to bet on the price of silver. They have no intention of owning physical silver. As a result, the COMEX can simply use its leverage to manipulate the paper price movements. And every time the price of silver has risen sharply for X reasons (often speculative), the COMEX has always managed to change the rules to kill the silver price. Today, people are saying it's different because there's a shortage in COMEX reserves and the physical price in certain places, especially Shanghai, is varying between $120 and $130. Indeed, this year China has placed small orders to withdraw massive amounts of physical silver from the COMEX. However, that doesn't change the rules of the game at all. Physical silver demand is far greater than supply, and yet the silver price hasn't particularly increased. The only thing that has driven up COMEX prices is the Chinese intervention. And the COMEX has issued several successive margin calls to keep the silver price quite low. What about physical silver? From what I understand, mines don't sell at the true physical price. They sell at the paper silver price. Sometimes they build up stocks to sell later, anticipating higher prices. But paper silver prices always remain the compass for long-term contracts. So even if physical silver is selling for $130 in Shanghai, a Canadian mining company will sell it for $70 per ounce because the COMEX has kept the price down. In fact, I get the impression that this market is rotten. We're not investing in silver, but in a totally manipulated financial product.
