Think you need to get your facts right first -

Comex were about to default not due to the price crashing-

"
    On June 1, 2015, JPMorgan added almost exactly enough ounces of physical gold to patch the deficiency between supply and delivery demand at COMEX, avoiding widespread dealer default.
    Declassified documents, along with strong circumstantial evidence indicate that it was not JPMorgan, but its most important customer, the US Federal Reserve, that just bailed out COMEX.
    The deficit in world physical gold supply will be at least 606.1 tons in 2015, but may be much larger, and similar incidents are likely in the future.
    The deficit in world gold supply versus demand will grow much larger in 2016 and beyond.
    Even if the entire remaining US gold reserves were mobilized, prices could not be permanently held down to current levels, making gold and gold mining stocks a good deal now.

Gold is suppressed not propped up.

Average sustained costs of mining 1oz gold is $919, also add in transport costs, minting and retail costs and I think your 4X value is bullshit.

Wait until china goes pop followed by a few EU countries then we'll see if gold is currently 4X real price!

p.s. I also suggest you read up on current gold/silver demand and shortfalls in physical supply.
