According to wikipedia, roughly 5.3 billion troy ounces of gold have been mined in all of human history. Gold is currently trading at around $1600 a troy ounce which means that the total market value of all of the world's mined gold is approximately $8.5 trillion. The demand for gold (and hence its price) is not driven entirely by its monetary usefulness because it has other uses such as jewelry and electronics. But a non-trivial fraction of its price comes from its usefulness as money. How big is that fraction? Let's be conservative and say it's only 25%. That means that gold's total "money value" is around $2 trillion. Let's pretend as a simplifying assumption that all 21 million bitcoins have been mined. The total value of those coins based on a current price of $6.40 is $134 million. 134 million is smaller than 2 trillion. Bitcoin is supposedly a "better" money than gold when you evaluate it according to all the characteristics that make for good money, e.g., it's divisible, fungible, durable, portable, identifiable, and scarce. And yet, (using all of the previous assumptions) if bitcoins were valued ONLY 1/1000th as much as "monetary" gold, they'd be worth a total of $2 billion, i.e. roughly $95 / BTC. If they were valued AS MUCH as monetary gold, they'd be worth $95,000 a piece. Of course, since bitcoins are at least 10 times BETTER than gold, they should really be worth no less than $950,000 each. And yet, I can't help but notice that I still live with my parents and drive an '89 Geo Metro. That raises a few questions:
1) Why aren't I filthy rich yet?
2) Any other dreamers willing to post their pie-in-the-sky, insanely bullish predictions for what a bitcoin could be worth in terms of purchasing power if it proves to be as revolutionary as we hope it will be?
AND
3) It seems like a lot of people are very focused on bitcoin's adoption by merchants, i.e. the "medium of exchange" aspect of currency, as the key to its success. But couldn't bitcoin still be insanely successful (in terms of its value) if it took off ONLY as a store of value? (And isn't that mostly how gold is used?)
Well, two years later, hopefully you are
not NOW filthy rich, market cap now @ 4 billion.
Sorry it took so long!
