More on Market Update 19 Jul 2013: Gold Stocks Bottom?

Markets were lower this week, with the exception of Bitcoin, which recovered all of last week's loss,  and platinum, which was almost unchanged.

Bitcoin gained 28.5% to close at 2.34 g., erasing last week's big decline. Trading volume continued to rise, averaging about 108 kg per day. Expect extreme volatility to continue, but with an upward bias over the long term. Bitcoin still represents a unique value proposition, offering, like precious metals, an asset that is not anyone's liability… but with the ease of instantaneous transmission over the internet coupled with a cash-like level of privacy. As monetary disaster continue to unfold in Europe, Japan and the US, expect to see growing interest in Bitcoin.
