What is the lifespan of a series of currency?
In general, currency has no expiration date. Specifically, in Canada, the Bank of Canada has been issuing banknotes since 1935, and these are still considered legal tender, even though they don't look much like the modern banknotes.  Before that, Canadian chartered banks issued currency, and these also still have value. However, there are a few things to note.  First of all, with currency of that age, it often has more value as a collector's item than the face value.  So spending it at a store would be foolish. Second, store clerks are not experts in old currency, and will not accept a bill that they do not recognize.  If you want the face value of your old currency, you may need to exchange it for modern currency at a bank. Having said all that, there are certainly cases where currency does expire.  Generally this happens when a country changes currency.  For example, when the Euro was introduced, the old currencies were discontinued.  After a window of exchange, the old currency in many cases lost its value.  So if you have some old French Franc notes, for example, they can no longer be exchanged for Euros. These types of events cannot be predicted in the future, of course, so it is impossible to say when, if ever, the Canadian currency you have today will lose its spending value in Canada. US currency doesn't expire, it is always legal tender.  I can see some trouble if you tried to spend a $10,000 bill (you'd be foolish to do so, since they are worth considerably more). Maybe some stores raise eyebrows at old-style $100's (many stores don't take $100 bills at all), but you could swap them for new style at a bank if having trouble with a particular store. Old-series currency can be an issue when trying to exchange US bills in other countries, just because it doesn't expire here, doesn't mean you can't run into issues elsewhere. Other countries have different policies, for example, over the last year the UK phased in a new five pound note, and as of last month (5/5/2017) the old fiver is no longer considered legal tender (can still swap out old fivers at the bank for now at least).  Edit: I mistook which currency you took where, and focused on US currency instead of Canadian, but it looks like it's the same story there. "Currency lives no more then 50 years. US currency did not expire in last 100 years, but it was reinstated few times, last one was 2009. Note that currency is not just what you hold in your hand. Currency is system of relations of money supply (currency is not money but we forced to use standard terminology), banking rules and government policy. Currency exists as long as government wants it to. In 2009 for example, US government decided it needs new currency and just printed whole new money supply. So US dollar is now counting as ""partially fresh new currency"". It was reinstated. Not expired. But today's dollar is totally different from 90s and 00s. Will it be accepted after 200 years? Yes (probably). But most likely at that time there will be totally new US dollars. And new Euros, new Pounds and so on. Currency is method of transfer. You can have that physical coins you have, but as economic agent it will die very quickly. It is not only related to inflation, in fact, inflation is the least of your worries. If you count all currencies in the world which ever existed, most of them 99.99% are completely dead by now (with governments which supported it). Not even single one currency which lived more then 100 years. US dollar was reinstated in 1860, 1907, 1930, 1973, 1987, 2009 and  in fact it is not single currency but dozen which were allowed to be used ""for compatibility reasons""."
"Q: How do currency markets work? A: The FX (foreign exchange) market works very much like the stock market where potential buying parties bid $Y of country 1's currency to buy $1 in country 2's currency.  Potential selling parties sell (ask) $1 of country 2's currency for $Y of country 1's currency.  Like the stock market, there are also a swaps, futures and options in this market. Q: What factors are behind why currencies go up or down? A: Just like any open market, currencies go up and down based on supply and demand.  Many factors affect the supply and demand of a particular currency.  Some were listed well by the other posts. Q: What roles do governments, central banks, institutions, and traders have in the process? A: It's common practice that gov'ts intervene to ""control"" the value of currencies.  For example, although it's not general public knowledge, the Canadian gov't is actively purchasing up US dollars in the FX market in an effort to stop the US/Canadian exchange rate from dropping further.  This has dramatic economic consequences for the Canadian ecomony if the Canadian dollar were to strengthen too far and too quickly." "In June 2016 the American Institute of CPAs sent a letter to the IRS requesting guidance on this question.   Quoting from section 4 of this letter, which is available at https://www.aicpa.org/advocacy/tax/downloadabledocuments/aicpa-comment-letter-on-notice-2014-21-virtual-currency-6-10-16.pdf If the IRS believes any property transaction rules should apply differently to virtual currency than to other types of property, taxpayers will need additional guidance in order to properly distinguish the rules and regulations. Section 4, Q&A-1 of Notice 2014-21 states that “general tax principles applicable to property transactions apply to transactions using virtual currency,” which is guidance that is generally helpful in determining the tax consequences of most virtual currency transactions. However, if there are particular factors that distinguish one virtual currency as like-kind to another virtual currency for section 1031 purposes, the IRS should clarify these details (e.g., allowing the treatment of virtual currency held for investment or business as like-kind to another virtual currency) in the form of published guidance. Similarly, taxpayers need specific guidance of special rules or statutory interpretations if the IRS determines that the installment method of section 453 is applied differently for virtual currency than for other types of property. So, at the very least, a peer-reviewed committee of CPAs finds like-kind treatment to have possible grounds for allowance.   I would disagree with calling this a ""loophole,"" however (edit: at least from the viewpoint of the taxpayer.)  At a base technological level, a virtual currency-to-virtual currency exchange consists of exchanging knowledge of one sequence of binary digits (private key) for another.  What could be more ""like-kind"" than this?" Yes, they're using it as a currency.  What they actually have demand for is houses and Lambos, and if bitcoin wasn't available they'd be happy to do it in any other currency.  When any other currency goes up it's because there's overall higher demand than supply for it, to buy things you can only buy in a particular currency.    A very common example is government bonds of the issuing government for a currency.  That's why when the Fed raises the interest rate, the US dollar goes up.  It is because at a bond auction the government will only take US dollars so anyone that wants to buy some bonds needs to first buy US dollars.  If the interest rate goes up, all things being equal those bonds are relatively more attractive than other countries bonds, and that change in demand increases the demand for the currency, which raises it's price.  Note the key thing here - it needs to be something you can only buy (or at least, buy for the cheapest price) in a particular currency.  If it's something you can buy with any currency, than that event generally doesn't impact the currency price.  Although it's a very important food crop, if the price of rice goes up, it doesn't really impact the USD even though you can buy rice with USD.  Here's the tricky part, what can you buy with bitcoin that you can't buy with any other currency?

But the elephant in the room is that the gov't can't let deflation happen or their debt becomes harder to pay off. So after/during a downturn the government goes into hyperinflation mode.  To me, gold/silver aren't a hedge against the dollar they are a hedge against the inevitable decline of the dollar which isn't going to stop until we change monetary policy.  Graph the dollar's value in the past 100 years, it's the biggest crash in history. Now ask yourself if the dollar was a stock, would you want to own it with that record? 100 years of declination. Sell your dollars, find a real currency. Less than 2 1/2% of all US currency actually exists.  The rest is digital entries.  In a financial crisis you'll need lots of rare cash.  Twenty dollar bills are the best choice.  Stash as many as you can afford to.  Best to stash in a anchored security safe.  And for goodness sakes, don't tell anyone. Well, define shitty.   The assumption of perfect competition should imply that only the firms that can manage to breakeven while still owing outstanding bonds will continue to issue bonds in the first place, as the competing monetary systems themselves will become a competitive market of their own.  Information on the specific bond you're using as a medium of exchange/legal tender should be easily be easy to find or public information.  If it's kind of bondnote has existed for five years with no substantial changes, my safe bet is on that bond being worth something. If we postulate that there is at least some element of truth to the phrase 'A leopard does not change his spots'  and then consider this tidbit He conveniently forgets to mention his 1.5 million dollar fraud fine   from the SEC over investment “advice” he sold through a news letter.   The SEC claimed and the judge agreed that the report was “replete with   lies”. I think that gives you just about all you might need to know regarding the man behind the video, and the nature of it's content.  Oh, and it's purpose?  To SELL YOU the same said newsletter. I guess it's natural for Stansberry to feel as he does. After all if the US gov had just busted me for conning and lying to folks, and fined ME 1.5Mill, I'd be having some pretty intense lurid fantasies about it going down in flames, and trying to hide any money I had left offshore also.   A huge amount of his argument hinges on the US no longer being the world's reserve currency.  Firstly, while I'll admit I'm none too happy with the way the national debt has been managed for oh, around 30 years how, (which includes I will note going from a pretty much balanced budget, to around an 80% increase in the debt from 2001 through 2008, when 'times were good' and there was little need to spend money we didn't have), when compared to a lot of other countries, we still don't look that bad.  You have to ask yourself this first, if not the US, then WHO?  are the governments of the world going to trust China? could the Yen handle the load?  Is the Euro any better off especially considering problems in Greece, Ireland, etc.  Do countries like Switzerland have enough liquidity and available ways to invest there?  In order for the US to STOP being the world's reserve currency, you must have something to replace it with, and really, can we realistically think of one country/currency with the capability to become a new 'world reserve currency'???  Secondly, even then should such a shift actually happen, it doesn't mean people will ALL just magically stop buying US debt.  Yes the demand would go down, but it would not go to zero.  There are after all a worldfull of other countries who's money is right now NOT the world reserve currency, and yet they are able to sell bonds and people and even other countries invest there. (China for example does not invest exclusively in the US), so yeah we might have to start paying more interest to get people to buy US debt, but it's not like the demand will go away.   Save your money, save your time, don't buy into this dung.
