>in the past 2 weeks we've seen its value appreciate by 50%, something that just doesn't happen with traditional currencies

It happens with gold, which could be viewed as a traditional currency.

Care to link to any graphs that support this? Gold isn't that volatile, even though it may have swings of $50 up/down every week that's 3%, far below the volatility we're seeing in the current BitCoin market.

I wrote the text of grandparent, realized it was wrong, but hit the "Reply" button was an accident. I agree gold is not as volatile as Bitcoin.

To be pedantic, and to note I'm not an economist, I thought the value of gold or silver was always constant, it was the currencies based on them that inflate or deflate.

"I thought the value of gold or silver was always constant"

Value is relative, so if you only value gold then the value of gold is constant. But if what you value is goods and services, then the price of gold is extremely unstable. You can see it graphed here (CPI being a metric of the price of goods and services):


Gold used to have a stable price in terms of dollars because the central bank pegged the currency to the price of gold, which I think is the reason people like Ron Paul believe that gold has a "constant" price. now the central bank pegs the currency to CPI so CPI is stable and gold floats freely (in dollar terms). This is preferable if you value CPI price stability more than gold price stability.

Also note that gold and silver often diverge in value relative to one another, so no matter what your perspective, it cannot be the case that gold and silver have stable value. If Somebody hits a rich silver vein then silver drops relative to gold.

Nope. As more gold was mined during gold rushes, the value of gold decreased. As people found more uses for gold and demand outstripped supply, the value increased. And of course the relative value of gold and silver changes over time.

Particularly, the discovery of the New World with all the gold there caused some huge disruptions in the Old World economy.

Makes sense.

> I thought the value of gold or silver was always constant

What is the unit in which value is measured? There is no SI unit for value, and it seems unlikely that it would ever be possible to define one - it would basically require very surprising breakthroughs in psychology.

Hence people do the pragmatic thing and measure value in the currency that is predominantly used in their life. They use USD or EUR or whatever as their unit of value.

And in that sense, the value of gold and silver is clearly not constant, as a sibling comment explains.
