However, the failure of some countries' currencies does not mean that people are going to switch from their nation's currency to Bitcoin. If the US Dollar were to fail, Bitcoin would be the last thing on anyone's mind; we would probably wind up switching to some other government's currency while we sorted out the mess (Yuan perhaps), or we would just spend our time killing each other and not worrying too much about money. Perhaps you just need a short list of reasons why Bitcoin is not going to replace government issued currencies: 1. No offline transactions, which makes Bitcoin useless for a large class of transactions. 2. Fixed upper bound on the number of currency units, which creates deflationary trends as economies and populations grow. 3. No governments allow tax payments made using Bitcoin, and there is no incentive for them to do so. Even if everyone used Bitcoin for day-to-day trades, they would still have to pay property taxes or face arrests, property seizures, etc. When the government becomes too ineffective to enforce its own laws, then Bitcoin might have a chance, but only as a way to manage trade in some foreign nations' currencies (who will still want to trade with people in the region where the government failed), and that is assuming that online transactions can even happen in such a situation. Now, I will grant you this: there is a very, very, very remote possibility that every fiat currency in the entire world will fail simultaneously, and that instead of shooting each other people will continue to engage in trade (and that the Internet survives the mess). Even in that case, there will need to be some currency for offline transactions, and so even then Bitcoin will be relegated to second place. -- Ben -- Benjamin R Kreuter UVA Computer Science brk...@virginia.edu KK4FJZ -- If large numbers of people are interested in freedom of speech, there will be freedom of speech, even if the law forbids it; if public opinion is sluggish, inconvenient minorities will be persecuted, even if laws exist to protect them. - George Orwell signature.asc Description: PGP signature ___ cryptography mailing list cryptography@randombit.net http://lists.randombit.net/mailman/listinfo/cryptography

Yes, governments just love to assess taxes, fees, and fines. No, I have no need of any of that. I do not follow your argument -- how does eliminating government issued money stop governments from collecting taxes and fees? Governments whose currencies fail sometimes switch to the currencies issued by other governments; there are quite a few nations that use US Dollars instead of issuing their own money. You may not like the idea of fines or fees, but how would you propose courts manage disputes between people? Suppose I fail to maintain my house, and a piece of it falls off and damages your house -- should you have to pay for my negligence? If I raise cattle and you write software, what should I give you -- a cow perhaps? Perhaps I should pay for a repairman to come and fix things -- but what if you do not like the person I choose? We have judges and courts to help us resolve these sorts of disputes, and money is a great way to ease these sorts of disputes. You may disagree with the taxes you pay, the fines that are issued, and so forth -- but would you really want to have a tax collector come and rate the quality of your work, and then take the products of that work as a form of tax payment? Do you want to see people imprisoned, enslaved, tortured, etc. instead of paying fines?

Rather, what motivates most gold purchasers (and thus most bitcoin purchasers) is their belief that their fears might well prove correct, that without gold, they might find themselves penniless refugees, or, worse, without even the ability to become penniless refugees, because they lack the funding to leave a collapsing society. Gold is an end of the world investment, insurance against total institutional collapse. We tend to underestimate fat tail risks such as total collapse, since the English speaking world has never had a total institutional collapse since the battle of Hastings in 1068. This however, is survivorship bias. In the rest of the world, total institutional collapse has been rather common. Warren Buffet correctly argues that gold will, on average, lose value. However there is a significant risk that everything except gold will lose value. Warren Buffet continues: A century from now the 400 million acres of farmland will have produced staggering amounts of corn, wheat, cotton, and other crops – and will continue to produce that valuable bounty, whatever the currency may be. Exxon Mobil will probably have delivered trillions of dollars in dividends to its owners and will also hold assets worth many more trillions (and, remember, you get 16 Exxons) Now let us apply this reasoning to Russian croplands in 1903.
