I'm looking for a chart of Bitcoin's price and market cap to other commodities like silver, gold, etc.
Does such a chart exist?
Why is this useful? Because I want to see how the USD compares to similar non-Fiat, limited quantity resources. This should show how Bitcoin is undervalued, or would give us insight into the trade volumes.
If it doesn't exist, I'll create it myself for the benefit of the community. Where can I get historic gold & silver pricing in USD?
