Skol, global attitudes to global economics will have to change for gold to fall 20%. With the current turmoil in Europe, and it's been going on for 5 years now, I think that it's safe to say that won't happen.
Also, the increased forgery of coins/bars coming out of china only indicates the direction gold will travel. (on that note, I'll bet paper money counterfeit is down at the moment, lol)
