If we have monetary deflation (the leverage is removed from the system) then I guess the price of Gold and Silver has to go down along with everything else.
The question would be how much do they go down with respect to other assets and comsumables.
As far as Buy and Hold verus trading goes I would love to be able to do this to protect my profits and then reinvest once the price has fallen unfortunately I don't have a crystal ball.
Also I know it's been covered 1000 times on here before but why assume we won't have hyperinflation and the currency be printed to destruction, surely that's the pattern of history, why will it be different this time, because the dollar is the global reserve?
