Gold bull runs - heading to $600

After weeks of boring times, Gold rise followed by Platinum breaking the record high.
The bull run starts at around $550 when spot gold goes up and down in the range $540-$570.

Gold breaks double top ($574) without difficulty and heading towards $600. It reaches a day high of $589 yesterday, and today it stays at $58x level, taking a rest and ready for another surge.

Now $600 seems a easy target to reach, then what's next ? Can it test $700 level, or even $800 ? The history high is $850 at 1980. Is it possible to climb to this level ?
