I know because I am a "Post Graduate in Precious Metals"and particularly Gold and Silver .
It is all there in the raw data -- paper contracts .
In summarised and overall terms :-
The Silver market was tabled to rise to $80 but was then to be shorted by the Whales ( Banks) .
To their horror , retailers ( us ) got involved and hysteria took the price close to $120 ( instead of back to $60-- $65 ) which literally endangered some household name international banks going out of business .
Essentially all in a couple of trading sessions .
Multi Billions were at stake .
So Gold was then shorted along with Silver, and for Gold the price fell from $5600 to $4600 and Silver from $120 to under $80 in hours .
Epic .
Super Colossal . Never before witnessed .
The Banks then cleared their potential paper losses and bought long.
After a huge rise again , the big Banks repeated the same rinse and drove Gold back from $5100 to $4600 and Silver from $90 to just below $70 .
Everybody then filled their boots -- obviously going Long .
Now prices are coming back and the movement north will continue but likely at a more leisurely pace .
That is how and why the real government is Deep .
Here is how they did it :-
