Does gold's value decrease over time due to the fact that it is being continuously mined?
"does it mean uncontrolled severe deflation/inflation is more likely to   occur compared to ""normal"" currencies such as USD, EUR etc? Look at the chart referenced in the link in your question.  It took approximately 50 years for annual production of gold to double from 500 tons to 1000 tons.  It took approximately 40 years for annual production to double from 1000 tons to 2000 tons. Compare that to the production of US dollars by the Federal Reserve (see chart below obtained from here).  US dollar production doubled in DAYS.  Which one do you think will lead to uncontrolled inflation/deflation? Update: Why did I include a chart of the FED's balance sheet?  Because this is the way newly printed money is introduced - the FED will purchase something from banks (mortgage-backed securities, US treasuries, etc.) with newly printed money.  The banks can then loan this money to people who then deposit the money into other banks who loan those deposits to other people and so on.  This is how the fractional reserve process expands the money supply.  This is why I did not include a chart of the money supply since that is counting the same money multiple times.  If I deposited 100 newly minted coins into a bank and that bank proceeded to loan out 80 of my coins where 80 are deposited into another bank who then proceeds to loan out 60 of the coins, and so on....the production of coins only changed by the initial 100 that I minted - not by the fractional reserve multiple. There are historical examples of inflation with gold and silver as duff has pointed out.  None of them come close in magnitude to the inflation experienced with government fiat money." As one can see here, the world population is growing. Assuming worldwide demand for gold is a function of population, the question you have to ask is whether gold mining outpaces population growth. Just eyeballing it, I'd say they're about even although annual production is far noisier. Keep in mind that gold extraction is not an easy process though. At the end of the day, gold is only worth what you can trade it for, just like any other store of value. Mining/discovery of gold can be inflationary -- the Spanish looting of Central America for a few hundred years or the gold rush in the 19th century US are examples of that phenomenon. The difference between printing currency and mining is that you have to ability to print money on demand, while mining is limited to whatever is available to extract at a given time. The rising price of gold may be contributing to increased production, as low-grade ore that wasn't economically viable to work with in the 1980's are now affordable. "The relative value of Gold (or any other commodity) as measured against any given currency (such as the USD), is not a constant function either. If you have inflationary pressure, the ""value"" of an ounce of gold (or barrel of oil, etc) may ""double"", but it's really because the underlying comparator has lost ""half"" its value." Contrary to Muro's answer which strangely shows a graph of the Fed's balance sheet and not the money supply, the supply of US dollars has never doubled in a few days.  This graph from Wikipedia shows M2, which is the wider measure of money supply, to have doubled over approximately 10 years, http://en.wikipedia.org/wiki/File:Components_of_US_Money_supply.svg The answer to whether gold has a higher chance of experiencing big devaluation has to do with forces outside anyone's control, if a big new mine of gold is discovered that could affect prices, but also if the economy turns around it could lead investors to pull out of gold and back into the stock markets. The USD, on the other hand, is under control of the policy makers at the Fed who have a dual mandate to keep inflation and unemployment low. The Fed seems to have gotten better over the last 30 years at controlling inflation and the dollar has not experienced big inflation since the 70s. Inflation, as measured by Core CPI, has been maintained at less than 4% for the last 20 years and is currently coming off record low levels below 1%. The previous answers have raised very good points, but I believe one facet of this has been neglected. While it's true that the total accessible supply of gold keeps growing(although rather slowly as was mentioned earlier) the fact remains that gold, like oil, is a non-renewable natural resource. So, at some point, we are going to run out of gold to mine. Due to this fact, I believe gold will always be highly valued. Of course it can certainly always fluctuate in value. In fact, I expect in the reasonably near future to see a decline in the price of gold due to investors selling it en masse to re-enter the stock market when the economy has recovered more substantially. Does gold's value decrease over time due to the fact that it is being continuously mined? Remember that demand increases and decreases - we've had seven years or so of strong demand increase and the corresponding price increase suggests there is a lack of gold coming into the market rather than too much. Also, bear in mind that mining the stuff on any scale is hazardous and requires massive investment in infrastructure and time. Large mines frequently take seven to ten years to come on-stream - hardly an elastic enterprise. There is another aspect too for the high prices of GOLD. After the current economical crisis people are no more investing in property and a big chunk of investment has been diverted to GOLD. "Like anything else, the price/value of gold is driven by supply and demand. Mining adds about 2% a year to the supply. Then the question is, will the demand in a given year rise by more or less than 2%. ON AVERAGE, the answer is ""more."" That may not be true in any given year, and was untrue for  whole DECADES of the 1980s and 1990s, when the price of gold fell steadily.  On the other hand, demand for gold has risen MUCH more than 2% a year in the 2000s, for reasons discussed by others. That is seen in the six-fold rise in price, from about $300 an ounce to $1800 an ounce over the past ten years."
I think part of the confusion is due to the age of the term and how money has changed over time relative to being backed by precious metals vs using central banks etc. Historically: Because historically the coin itself was precious metal, if a change occurred between the 'face value' of the coin and value of the precious metal itself, the holder of the coin was less affected since they have the precious metal already in hand. They could always trade it based on the metal value instead of the face value. OTOH if you buy a note worth an the current price of ounce of gold, and the price of gold goes up, and then the holder wants to redeem the note, they end up with less than an ounce of gold. In the more modern age  The main concern is the cost to borrow funds to put money into circulation, or the gain when it goes out of circulation.  The big difference between the two is that bills tend stay in circulation until they wear out, have to be bought back and replaced.  Coins on the other hand last longer, but have a tendency to drop out of circulation due to collectors (especially with 'collectible series' coins that the mint seems to love to issue lately).  This means that bills issued tend to stay in circulation, while only a percentage of coins stays in circulation.  So the net effect on the money supply is different for the two, and since modern 'seigniorage' is all about the cost to put money in circulation, it is different in the case of coins where some percentage will not remain circulating. No, it doesn't matter how powerful the machines are that do the mining. The system balances it out (increases the difficulty) so that one block is mined every 10 minutes, regardless of whether there's 500 miners in the world or 50 million, it will always be around 10 minutes (sometimes 9 and sometimes 11 though). And one block used to be 50BTC, but every 4 years this halves and so in 100 years the supply increase will be almost 0, miners will still get the transaction fees though.   This means bitcoin is limited to a supply of less than 21 million. Which creates the scarcity.  There's possibly a problem though. Quantum computing might not increase the supply but it could potentially decrypt the encryption, but if that happens the whole internet and digital world will be in trouble and not just bitcoin. If that fraction is really small, then the amount of gold can be thought of as relatively constant. That fraction is very small. After all, people have been mining gold for thousands of years. So the cumulative results of gold mining have been building up the supply for quite some time. Meanwhile, owners of gold rarely destroy it. A little bit of gold is used in some industries as a consumable. This limited consumption of gold offsets some of the production that comes from mining. But truthfully this effect is minuscule. For the most part people either hoard it like its made of gold, or sell it (after all it is worth its weight in gold). If you're interested Wikipedia lists a few more factors that affect gold prices. (If you're not interested Wikipedia lists them anyway.) It’s an investment and a currency which is also based no less than the value it takes to mine... so yeah you’re right if people who are involved in bitcoin decide it’s not worth the time to have a currency it will become worth less than it take to mine.. but it’s worth 102b do I don’t think it’s gonna happen. What you are seeing is the effects of inflation. As money becomes less valuable it takes more of it to buy physical things, be they commodities, shares in a company's stock, and peoples time (salaries).  Just about the only thing that doesn't track inflation to some degree is cash itself or money in an account since that is itself what is being devalued.  So the point of all this is, buying anything (a house, gold, stocks) that doesn't depreciate (a car) is something of a hedge against inflation. However, don't be tricked (as many are) into thinking that house just made you a tidy sum just because it went up in value so much over x years. Remember 1) All the other houses and things you'd spend the money on are a lot more expensive now too; and 2) You put a lot more money into a house than the mortgage payment (taxes, insurance, maintenance, etc.) I'm with the others though. Don't get caught up in the gold bubble. Doing so now is just speculation and has a lot of risk associated with it. Gold since the ancient time ( at least when it was founded) has kept its value. for example the french franc currency was considered valuable in the years 1400~ but in 1641 lost its value. However who owned Gold back then still got value.  The advantage of having gold is you can convert it to cash easily in the world. it hedges against inflation: it is value rise when inflation happend. Gold has no income,no earnings. its not like a stock or a bond. its an alternative way to store value the Disadvantages of investing in Gold  Gold doesnt return income , needs physical storage and insurance, Capital gains tax rates are higher on most gold investments. the best way to invest gold when there is inflation is expected. source There is no such thing as intrinsic value. Gold has value because it is rare and has a market. If any of those things decline, the value plunges. The question of whether gold is overvalued or not is complicated and depends on a lot of factors.  The key question in my mind is: Is gold more valuable in terms of US dollars because it is becoming more valuable, or because the value of US dollars, the prevailing medium of exchange, is declining? Not at the current price.  Take a look at historical charts going back five years. When the meltdown occurred in 2008, gold price took a big dip due to deleveraging, etc. I would expect the same to happen again with the current crisis. It seems that you're interested in an asset which you can hold that would go up when the gold price went down. It seems like a good place to start would be an index fund, which invests in the general stock market. When the gold market falls, this would mainly affect gold mining companies. These do not make up a sizable portion of any index fund, which is invested broadly in the market. Unfortunately, in order to act on this, you would also have to believe that the stock market was a good investment.   To test this theory, I looked at an ETF index fund which tracks the S&P 500, and compared it to an ETF which invests in gold.  I found that the daily price movements of the stock market were positively correlated with the price of gold. This result was statistically significant.  The weekly price movements of the stock market were also correlated with the price of gold. This result was also statistically significant.  When the holding period was stretched to one month, there was still a positive relationship between the stock market's price moves and the price of gold. This result was not statistically significant.  When the holding period was stretched to one year, there was a negative relationship between the price changes in the stock market and the price of gold.  This result was not statistically significant, either. Gold is not really an investment at all, because it doesn't generate an income. It's only worth money because people think it's worth money (it has some industrial uses, but most gold is used as a store of value and not for industrial purposes), not because of its income stream. I own a gold mine and my cost of producing an ounce of gold is $600. Less than that, I lose money, anything over is profit. Today, at $1500, I sell futures to match my production for the next 2 years. I'm happy to lock in the profit. If gold goes to $3000, well, too bad, but if it drops to $500, I can still sell it for the $1500 as I mine it. I suppose I could also close out the contracts at a profit and still shut the mines down, but the point is illustrated. Cute, but 100 years of market history will show you the fundamentals have persisted for a reason. Every industry in history has tried to pull this “but this is different” thing off (oil, gold, semiconductors) and they have ALL been brought to reality in time. There is no reason to think today is any different. There will  be recessions again, there will be market crashes again, either tomorrow or 5 years from now. It always levels out. "OK, reading between the lines here it looks like the services offered by your company are of an ""adult"" (possibly illegal?) nature and that this individual has actually paid you in full for the services rendered up to this point. The wrinkle here is that you say that you've been offered large cash ""gifts"" in return for unspecified future favours, but that your client hasn't provided a real Paypal account to do so. When you pressed him on it, he sent a fake email and invented a ""financial adviser"" to fob you off, then hasn't contacted you  since. It's pretty clear that he hasn't got any intention of making these payments to you. What you're now proposing to do is to use his known banking details to collect money to cover those verbal promises. In pretty much every part of the world, that's a crime. Without a written agreement to use that payment method for those promises, he could easily call the police and have you arrested for theft of funds. The further wrinkle is that his actions (claiming to have made payment via paypal, forged email headers, etc) strongly suggest that this individual is involved in cyber-crime and may well have used a fake bank account to pay for your initial services.  The bottom line here is that you need real legal advice, from an actual lawyer." In general you will take home more in the US than in Canada. There are so many variables that is is impossible to provide a comprehensive answer that will cover all bases: so here are a few hand-waving statements. Two example calculator web sites for Canada and the US (chosen somewhat at random through Google, show that making $50,000 of either currency for the upcoming tax year in Canada you would expect to pay about $9,100 and for the US $5,900.  Missing there are the state taxes, however, which also vary wildly. The deductions, adjustment and credits in both countries can really add up, so if you have specific questions, you should consult a tax specialist. Similarly, both countries provide various tax sheltered investment structures that change the game somewhat over the long term.
