More out of curiosity than of significant importance I am wondering why (currently) abt 180,000 show on the sell side.
I ask my self why are they selling. I can think of the usual's, like needing money to buy a new car, house, holiday etc but shared between such a large number of sellers that doesn't appear to be the reason. Doubt about the future for GCY and Gold?. To me that doesn't hold water, but everyone is entitled to their own view. Taking profit then?. That makes almost no sense either. The profit available to any of them is peanuts. Why be in the market for that sort of return.
Maybe someone out there can enlighten dumb old me and ease my curiosity
