Bitcoin is just like all other digital currencies; nothing new
Nearly all other digital currencies are centrally controlled. This means that:
- they can be printed at the subjective whims of the controllers
- they can be destroyed by attacking the central point of control
- arbitrary rules can be imposed upon their users by the controllers
Being decentralized, Bitcoin solves all of these problems.
Bitcoins don't solve any problems that fiat currency and/or gold doesn't solve
Unlike gold, bitcoins are:
- easy to transfer
- easy to secure
- easy to verify
- easy to granulate
Unlike fiat currencies, bitcoins are:
- predictable and limited in supply
- not controlled by a central authority (such as The United States Federal Reserve)
Unlike electronic fiat currency systems, bitcoins are:
- potentially anonymous
- faster to transfer
- cheaper to transfer
Bitcoin is backed by processing power
It is not correct to say that Bitcoin is "backed by" processing power. A currency being "backed" means that it is pegged to something else via a central party at a certain exchange rate yet you cannot exchange bitcoins for the computing power that was used to create them. Bitcoin is in this sense not backed by anything. It is a currency in its own right. Just as gold is not backed by anything, the same applies to Bitcoin.
The Bitcoin currency is created via processing power, and the integrity of the block chain is protected by the existence of a network of powerful computing nodes from certain attacks.
Bitcoins are worthless because they aren't backed by anything
Gold isn't backed by anything either. Bitcoins have properties resulting from the system's design that allows them to be subjectively valued by individuals. This valuation is demonstrated when individuals freely exchange for or with bitcoins. Please refer to the Subjective Theory of Value.
See also: the "Bitcoin is backed by processing power" myth.
The value of bitcoins are based on how much electricity and computing power it takes to mine them
This statement is an attempt to apply to Bitcoin the labor theory of value, which is generally accepted as false. Just because something takes X resources to create does not mean that the resulting product will be worth X. It can be worth more, or less, depending on the utility thereof to its users.
In fact the causality is the reverse of that (this applies to the labor theory of value in general). The cost to mine bitcoins is based on how much they are worth. If bitcoins go up in value, more people will mine (because mining is profitable), thus difficulty will go up, thus the cost of mining will go up. The inverse happens if bitcoins go down in value. These effects balance out to cause mining to always cost an amount proportional to the value of bitcoins it produces.
Bitcoins have no intrinsic value (unlike some other things)
It is true that bitcoins have no intrinsic value, in the numismatic sense, in other words, value in any realm outside of being used as a medium of exchange.
However, while some tangible commodities do have intrinsic value, that value is generally much less than its trading price. Consider for example that gold, if it were not used as an inflation-proof store of value, but rather only for its industrial uses, would certainly not be worth what it is today, since the industrial requirements for gold are far smaller than the available supply thereof.
While historically intrinsic value, as well as other attributes like divisibility, fungibility, scarcity, durability, helped establish certain commodities as mediums of exchange, it is certainly not a prerequisite. While bitcoins lack 'intrinsic value' in this sense, they make up for it in spades by possessing the other qualities necessary to make it a good medium of exchange, equal to or better than commodity money.
Value is ultimately determined by what people are willing to trade for - by supply and demand.
Bitcoins are illegal because they're not legal tender
Chickens aren't legal tender either, but bartering with chickens is not illegal.
There are a number of currencies in existence that are not official government-backed currencies. A currency is, after all, nothing more than a convenient unit of account. While national laws may vary from country to country, and you should certainly check the laws of your jurisdiction, in general trading in any commodity, including digital currency like Bitcoin, BerkShares, game currencies like WoW gold, or Linden dollars, is not illegal.
Bitcoin is a form of domestic terrorism because it only harms the economic stability of the USA and its currency
http://en.wikipedia.org/wiki/Definitions_of_terrorism#United_States according to this, you need to do violent activities to be considered a terrorist for legal purposes. Recent off-the-cuff remarks by politicians have no basis in law or fact.
Also, Bitcoin isn't domestic to the US or any other country. It's a worldwide community. See this map of Bitcoin nodes https://bitcointalk.org/?topic=2346.0
Bitcoin will only enable tax evaders which will lead to the eventual downfall of civilization
Cash transactions hold the same level of anonymity but are still taxed successfully. It is up to you to follow the applicable state laws in your home country, or face the consequences.
While it may be easy to transfer bitcoins anonymously, spending them anonymously on tangibles is just as hard as spending any other kind of money anonymously. Tax evaders are often caught because their lifestyle and assets are inconsistent with their reported income, and not necessarily because government is able to follow their money.
Bitcoins can be printed/minted by anyone and are therefore worthless
Bitcoins are not printed/minted. Instead, Blocks are computed by miners and for their efforts they are awarded a specific amount of bitcoins and transaction fees paid by others. See Mining for more information on how this process works.
Bitcoins are worthless because they're based on unproven cryptography
SHA256 and ECDSA which are used in Bitcoin are well-known industry standard algorithms. SHA256 is endorsed and used by the US Government and is standardized (FIPS180-3 Secure Hash Standard). If you believe that these algorithms are untrustworthy then you should not trust Bitcoin, credit card transactions or any type of electronic bank transfer. Bitcoin has a sound basis in well understood cryptography.
Early adopters are unfairly rewarded
Early adopters are rewarded for taking the higher risk with their time and money. This argument is akin to saying that people who buy stock at a company IPO (Initial Public Offering) are unfairly rewarded. This argument also depends on bitcoin early adopters using bitcoins to store rather than transfer value. The daily trade on the exchanges (as of Jan 2012) indicates that smaller transactions are becoming the norm, indicating trade rather than investment.
In more pragmatic terms, "fairness" is an arbitrary concept that is improbable to be agreed upon by a large population. Establishing "fairness" is no goal of Bitcoin, as this would be impossible.
The majority of the 21 million Bitcoins still have not been distributed. By starting to mine or acquire bitcoins today, you too can become an early adopter.
21 million coins isn't enough; doesn't scale
One Bitcoin is divisible down to eight decimal places. There are really 2,099,999,997,690,000 (just over 2 quadrillion) maximum possible atomic units in the bitcoin design.
The value of "1 BTC" represents 100,000,000 of these. In other words, each is divisible by up to 10^8.
As the value of the unit of 1 BTC grows too large to be useful for day to day transactions, people can start dealing in smaller units, such as milli-bitcoins (mBTC) or micro-bitcoins (μBTC).
Bitcoins are stored in wallet files, just copy the wallet file to get more coins!
No, your wallet contains your secret keys, giving you the rights to spend your bitcoins. Think of it like having bank details stored in a file. If you give your bank details (or bitcoin wallet) to someone else, that doesn't double the amount of money in your account. You can spend your money or they can spend your money, but not both.
Lost coins can't be replaced and this is bad
Bitcoins are divisible to 0.00000001, so there being fewer bitcoins remaining is not a problem for the currency itself. If you lose your coins, all other coins will go up in value a little. Consider it a donation to all other bitcoin users.
A related question is: Why don't we have a mechanism to replace lost coins? The answer is that it is impossible to distinguish between a 'lost' coin and one that is simply sitting unused in someone's safe.
It's a giant ponzi scheme
In a Ponzi Scheme, the founders persuade investors that they’ll profit. Bitcoin does not make such a guarantee. There is no central entity, just individuals building an economy.
A ponzi scheme is a zero sum game. In a ponzi scheme, early adopters can only profit at the expense of late adopters, and the late adopters always lose. Bitcoin has an expected win-win outcome. Early and present adopters profit from the rise in value as Bitcoins become better understood and in turn demanded by the public at large. All adopters benefit from the usefulness of a reliable and widely-accepted decentralized peer-to-peer currency.
Finite coins plus lost coins means deflationary spiral
As deflationary forces may apply, economic factors such as hoarding are offset by human factors that may lessen the chances that a Deflationary spiral will occur.
Bitcoin can't work because there is no way to control inflation
Inflation is simply a rise of prices over time, which is generally the result of the devaluing of a currency. This is a function of supply and demand. Given the fact that the supply of bitcoins is fixed at a certain amount, unlike fiat money, the only way for inflation to get out of control is for demand to disappear. Temporary inflation is possible with a rapid adoption of Fractional Reserve Banking but will stabilize once a substantial number of the 21 million "hard" bitcoins are stored as reserves by banks.
Given the fact that Bitcoin is a distributed system of currency, if demand were to decrease to almost nothing, the currency would be doomed anyway.
The key point here is that Bitcoin as a currency can't be inflated by any single person or entity, like a government, as there's no way to increase supply past a certain amount.
Indeed, the most likely scenario, as Bitcoin becomes more popular and demand increases, is for the currency to increase in value, or deflate, until demand stabilizes.
The Bitcoin community consists of anarchist/conspiracy theorist/gold standard 'weenies'
The members of the community vary in their ideological stances.
Anyone with enough computing power can take over the network
CONFIRMED, see Weaknesses.
That said, as the network grows, it becomes harder and harder for a single entity to do so. Already the Bitcoin network's computing power is quite ahead of the world's fastest supercomputers, together.
What an attacker can do once the network is taken over is quite limited. Under no circumstances could an attacker create counterfeit coins, fake transactions, or take anybody else's money. An attacker's capabilities are limited to taking back their own money that they very recently spent, and preventing other people's transactions from receiving confirmations. Such an attack would be very costly in resources, and for such meager benefits there is little rational economic incentive to do such a thing.
Furthermore, this attack scenario would only be feasible for as long as it was actively underway. As soon as the attack stopped, the network would resume normal operation.
Bitcoin violates governmental regulations
There is no known governmental regulation which disallows the use of Bitcoin.
See also: the "Bitcoins are illegal because they're not legal tender" myth.
Fractional reserve banking is not possible
It is possible. See the main article, Fractional Reserve Banking and Bitcoin
Point of sale with bitcoins isn't possible because of the 10 minute wait for confirmation
It is true that transactions can sometimes take tens of minutes to become confirmed. Despite this, retailers can accept unconfirmed transactions with very little risk by simply 'listening' on the network for a double-spend transaction, or partnering with a company that provides this service. After a head start of merely several seconds, the original transaction would reach so much of the Bitcoin network that a fraudulent double-spend transaction would almost certainly be fruitless. An attacker would have to commit easily-detectable fraud, in person, several hundred or several thousand times, before one of these low-value double-spend attempts would likely succeed.
An attacker could work around the necessity of sending out a second fraudulent transaction to the Bitcoin network by attempting to solo-mine an attack block containing the attack transaction himself - temporarily withholding the block with the rest of the network - and then execute the fraudulent purchase within seconds, or minutes at most, of mining the attack block, before broadcasting the attack block. However, the cost of such an activity would dramatically outweigh the value of anything typically offered without a confirmation wait for several reasons.
First, mining a block (attack or otherwise) entitles the miner to a valuable block reward, and because the attack involves temporarily withholding the block from the network, the attacker would put himself in the likely position of his block becoming stale, which would result in forfeiture of the entire reward. Most solo miners solve less than one block per month, so this would represent the loss of proceeds of potentially several weeks of mining.
Second, it is not possible for a solo miner to know exactly when his mining activity will yield a block, and because the attack must be carried out within seconds or minutes of successfully mining a block, the attacker will not be able to know or plan in advance the brief window when the attack would be likely to succeed. While it may be easy for a determined attacker to get low-value items that are sold and delivered online instantly without waiting for confirmations (such as downloads), this unpredictability and the briefness of the opportunity would make it extremely difficult to commit any kind of fraud where real-life interaction is required, such as visiting a merchant or taking possession of goods. Petty shoplifting would be far simpler. Even if an attacker went forward with this attack, the retailer would be notified of the fraud the moment the attack block is released seconds later.
In short, the 10-minute wait for confirmation is only practically necessary when delivering goods of value that significantly exceed the block reward an attacker would have to risk to perform an attack and where recourse after delivery is practically nonexistent, such as money transfers.
After 21 million coins are mined, no one will generate new blocks
When operating costs can't be covered by the block creation bounty, which will happen some time before the total amount of BTC is reached, miners will earn some profit from transaction fees. However unlike the block reward, there is no coupling between transaction fees and the need for security, so there is less of a guarantee that the amount of mining being performed will be sufficient to maintain the network's security.
Bitcoin has no built-in chargeback mechanism, and this isn't good
Why some people think this is bad: Chargebacks are useful for limiting fraud. The person handling your money has a responsibility to prevent fraud. If you buy something on eBay and the seller never ships it, PayPal takes funds from the seller's account and gives you back the money. This strengthens the eBay economy, because people recognize that their risk is limited and are more willing to purchase items from risky sellers.
Why it's actually a good thing: Bitcoin is designed such that your money is yours and yours alone. Allowing chargebacks implies that it is possible for another entity to take your money from you. You can have either total ownership rights of your money, or fraud protection, but not both. That said, nothing inherent in the dollar or euro or any other currency is necessary for chargebacks to be possible, and likewise, nothing prevents the creation of PayPal-like services denominated in Bitcoin that provide chargebacks or fraud protection.
The statement "The person handling your money has a responsibility to prevent fraud" is still true; the power has been shifted into your own hands. Fraud will always exist. It's up to you to only send bitcoins to trusted entities. It is possible to trust an online identity without ever knowing their physical identity; see the OTC Web of Trust.
Quantum computers would break Bitcoin's security
Yes, but quantum computers don't yet exist and probably won't for a while. Bitcoin's security can be upgraded if this were considered an imminent threat.
See the implications of quantum computers on public key cryptography here http://en.wikipedia.org/wiki/Quantum_computer#Potential
The risk of quantum computers is also there for financial institutions, like banks, because they heavily rely on cryptography when doing transactions.
Bitcoin mining is a waste of energy and harmful for ecology
No more so than the wastefulness of mining gold out of the ground, melting it down and shaping it into bars, and then putting it back underground again. Not to mention the building of big fancy buildings, the waste of energy printing and minting all the various fiat currencies, the transportation thereof in armored cars by no less than two security guards for each who could probably be doing something more productive, etc.
As far as mediums of exchange go, Bitcoin is actually quite economical of resources, compared to others.
Economic Argument 1
Bitcoin mining is a highly competitive, dynamic, almost perfect, market. Mining rigs can be set up and dismantled almost anywhere in the world with relative ease. Thus, market forces are constantly pushing mining activity to places and times where the marginal price of electricity is low or zero. These electricity products are cheap for a reason. Often it’s because the electricity is difficult (and wasteful) to transport, difficult to store, or because there is low demand and high supply. Using electricity in this way is a lot less wasteful than simply plugging a mining rig into the mains indiscriminately.
For example, Iceland produces an excess of cheap electricity from renewable sources, but it has no way of exporting electricity because of its remote location. It is conceivable that at some point in future Bitcoin mining will only be profitable in places like Iceland, and unprofitable in places like central Europe, where electricity comes mostly from nuclear and fossil sources.
Market forces could even push mining into innovative solutions that have an effective electricity consumption of zero. Mining always produces heat equivalent to the energy consumed - for example, 1000 watts of mining equipment produces the same amount of heat as a 1000 watt heating element used in an electric space heater, hot tub, water heater, or similar appliance. Someone already in a willing position to incur the cost of electricity for its heat value alone could run mining equipment specially designed to mine bitcoins while capturing and utilizing the heat produced, without incurring any energy costs beyond what they already intended to spend on heating.
Economic Argument 2
When the environmental costs of mining are considered, they need to be weighed up against the benefits. If you question Bitcoin on the grounds that it consumes electricity, then you should also ask questions like this: Will Bitcoin promote economic growth by freeing up trade? Will this speed up the rate of technological innovation? Will this lead to faster development of green technologies? Will Bitcoin enable new, border crossing smart grid technologies? …
Dismissal of Bitcoin because of its costs, while ignoring its benefits, is a dishonest argument. In fact, any environmental argument of this type is dishonest, not just pertaining to Bitcoin. Along similar lines, it could be argued that wind turbines are bad for the environment because making the steel structure consumes energy.
Shopkeepers can't seriously set prices in bitcoins because of the volatile exchange rate
Your assumption is that bitcoins must be sold immediately to cover operating expenses. If the shopkeeper's back-end expenses were transacted in bitcoins as well, then the exchange rate would be irrelevant. Larger adoption of Bitcoin would make prices sticky. Future volatility is expected to decrease, as the size and depth of the market grows.
In the meantime, many merchants simply regularly pull the latest market rates from the exchanges and automatically update the prices on their websites. Also you might be able to buy a put option in order to sell at a fixed rate for a given amount of time. This would protect you from drops in price and simplify your operations for that time period.
Like Flooz and e-gold, bitcoins serve as opportunities for criminals and will be shut down
- Visa, MasterCard, PayPal, and cash all serve as opportunities for criminals as well, but society keeps them around due to their recognized net benefit.
- Hopefully Bitcoin will grow to the point where no single organization can disrupt the network, or would be better served by helping it.
- Terrorists fly aircraft into buildings, but the governments have not yet abolished consumer air travel. Obviously the public good outweighs the possible bad in their opinion.
- Criminal law differs between jurisdictions.
Bitcoins will be shut down by the government just like Liberty Dollars were
Liberty Dollars started as a commercial venture to establish an alternative US currency, including physical banknotes and coins, backed by precious metals. This, in and of itself, is not illegal. They were prosecuted under counterfeiting laws because the silver coins allegedly resembled US currency.
Bitcoins do not resemble the currency of the US or of any other nation in any way, shape, or form. The word "dollar" is not attached to them in any way. The "$" symbol is not used in any way.
Bitcoins have no representational similarity whatsoever to US dollars.
Of course, actually 'shutting down' Liberty Dollars was as easy as arresting the head of the company and seizing the offices and the precious metals used as backing. The decentralized Bitcoin, with no leader, no servers, no office, and no tangible asset backing, does not have the same vulnerability.
Bitcoin is not decentralized because the developers can dictate the software's behavior
The Bitcoin protocol was originally defined by Bitcoin's inventor, Satoshi Nakamoto, and this protocol has now been widely accepted as the standard by the community of miners and users.
Though the developers of the original Bitcoin client still exert influence over the Bitcoin community, their power to arbitrarily modify the protocol is very limited. Since the release of Bitcoin v0.3, changes to the protocol have been minor and always in agreement with community consensus.
Protocol modifications, such as increasing the block award from 50 to 100 BTC, are not compatible with clients already running in the network. If the developers were to release a new client that the majority of miners perceives as corrupt, or in violation of the project’s aims, that client would simply not catch on, and the few users who do try to use it would find that their transactions get rejected by the network.
There are also other Bitcoin clients made by other developers that adhere to the Bitcoin protocol. As more developers create alternative clients, less power will lie with the developers of the original Bitcoin client.
Bitcoin is a pyramid scheme
Bitcoin is nearly opposite of a pyramid scheme in a mathematical sense. Because Bitcoins are algorithmically made scarce, no exponential benefit is derived from introducing new users to use of it. There is a qualitative benefit in having additional interest or demand, but this is in no way exponential.
