You would expect gold options to have a positive vol skew, but the skew is not consistently skewed one way or another. It just depends on sentiment at any point in time.
The relative volatility (realized) of the miners vs gold depends on which trading instrument you are using for gold. If you're using the ETF, then the miners are usually more volatile (at least recently). Of course, if you're trading gold futures which are highly leveraged, then they will be more volatile than the miners equities.
If you think gold will crash medium term, you may wait until next week in case Greece does blow up. It sounds like the odds of a bank run n Greece is fairly high.
If that happens there would likely be at least a temporary pop in gold.
You might get a much better price in a week or two. At least save some room to average, in case it does pop up.
greece is blowing up and gold is not moving. I don't see how anyone could be long gold at this point with metals and oil collapsing and dollar appreciating and China demand collapsing.
