Bitcoin also had a particular practical benefit as well. It allowed users to make payments online faster and more cheaply than they could through banks, a situation that has very recently changed as banks have moved to faster payment processing.

Some people like using Bitcoin as a way to buy and sell stuff. A number of retailers, including Expedia, Overstock. But because of the volatility of its price, using Bitcoin for day-to-day transactions has become trickier, says Justin Brookman, director of consumer privacy and technology policy for Consumers Union, the policy and mobilization division of Consumer Reports. The founders of the currency capped the number of Bitcoin that can be issued at 21 million, making it inflation-proof.

Just this week the Chicago Mercantile Exchange opened a market where investors can now place bets on Bitcoin futures. Sixteen million Bitcoin are in circulation at present. One is to pay cash money to someone who owns Bitcoin and have that person transfer it to you. The process is similar to the way peer-to-peer cash payment systems such as Venmo operate. The seller accesses his Bitcoin wallet—an app on his laptop or smartphone— which contains the currency.

He then selects the number of Bitcoin to transfer to you and hits the send button. You get a code representing the Bitcoin and you add it to your Bitcoin wallet. Another option is to go to an online cryptocurrency exchange such as Coindesk, GDax or Kraken. You tell the exchange how much Bitcoin you want to purchase and it walks you through the process. If you have a small business, you can also set up the wallet that works with Bitcoin or other cryptocurrencies and advertise that you accept Bitcoin as payment.

Mining is how new Bitcoin are created. It generally requires special hardware and software, so it's not practical for most people. The idea is to join a network of computers that processes complex mathematical problems. The computers that solve the most problems first are the ones that usually earn the most Bitcoin. Again, this is not for average people. It is. The biggest risk for investors is that the value of Bitcoin has risen so much that the market is now considered in a bubble.

That volatility was clearly evident in how the currency traded this week. There are other risks, too. The Consumer Financial Protection Bureau has warned consumers about the risks of Bitcoin transactions and investments. While there are few regulations of Bitcoin in place, some states are taking steps to regulate currency exchanges selling Bitcoin, says Christina Tetreault, staff attorney for Consumers Union, the policy and mobilization division of Consumer Reports.

M1 is M0 plus demand deposits like checking accounts. M2 is M1 plus savings accounts and small time deposits known as certificates of deposit in the United States. M3 is M2 plus large time deposits and money market funds. Since M0 and M1 are readily accessible for use in commerce, we will consider these two buckets as medium of exchange, whereas M2 and M3 will be considered as money being used as a store of value. As part of their monetary policy, most governments maintain some flexible control over the supply of currency in circulation, making adjustments depending upon economic factors.

This is not the case with Bitcoin. So far, the continued availability of more tokens to be generated has encouraged a robust mining community, though this is liable to change significantly as the limit of 21 million coins is approached. What exactly will happen at that time is difficult to say; an analogy would be to imagine the U. Fortunately, the last Bitcoin is not scheduled to be mined until around the year This can be seen with precious metals like gold. Fortunately, Bitcoin is divisible up to 8 decimal points.

This allows for quadrillions of individual units of Satoshis to be distributed throughout a global economy. One bitcoin has a much larger degree of divisibility than the U. While the U. It is this extreme divisibility which makes bitcoin's scarcity possible; if bitcoin continues to gain in price over time, users with tiny fractions of a single bitcoin can still take part in everyday transactions.

One of the biggest selling points of Bitcoin has been its use of blockchain technology. Blockchain is a distributed ledger system that is decentralized and trustless, meaning that no parties participating in the Bitcoin market need to establish trust in one another in order for the system to work properly. This is possible thanks to an elaborate system of checks and verifications which is central to the maintenance of the ledger and to the mining of new Bitcoins.

Best of all, the flexibility of blockchain technology means that it has utility outside of the cryptocurrency space as well. Thanks to cryptocurrency exchanges, wallets, and other tools, Bitcoin is transferable between parties within minutes, regardless of the size of the transaction with very low costs.

The process of transferring money in the current system can take days at a time and have fees. Transferability is a hugely important aspect of any currency. While it takes vast amounts of electricity to mine Bitcoin, maintain the blockchain, and process digital transactions, individuals do not typically hold any physical representation of Bitcoin in the process.

Durability is a major issue for fiat currencies in their physical form. A dollar bill, while sturdy, can still be torn, burned, or otherwise rendered unusable. Digital forms of payment are not susceptible to these physical harms in the same way. For this reason, bitcoin is tremendously valuable. It cannot be destroyed in the same way that a dollar bill could be. That's not to say, however, that bitcoin cannot be lost. If a user loses his or her cryptographic key, the bitcoins in the corresponding wallet may be effectively unusable on a permanent basis.

Thanks to the complicated, decentralized blockchain ledger system, bitcoin is incredibly difficult to counterfeit. Doing so would essentially require confusing all participants in the Bitcoin network, no small feat. The only way that one would be able to create a counterfeit bitcoin would be by executing what is known as a double spend. This refers to a situation in which a user "spends" or transfers the same bitcoin in two or more separate settings, effectively creating a duplicate record.

While this is not a problem with a fiat currency note—it is impossible to spend the same dollar bill in two or more separate transactions—it is theoretically possible with digital currencies. What makes a double spend unlikely, though, is the size of the Bitcoin network. By controlling a majority of all network power, this group could dominate the remainder of the network to falsify records.

However, such an attack on Bitcoin would require an overwhelming amount of effort, money, and computing power, thereby rendering the possibility extremely unlikely. Generally, Bitcoin holds up fairly well in the above categories when compared against fiat currencies. So what are the challenges facing Bitcoin as a currency? One of the biggest issues is Bitcoin's status as a store of value.

Bitcoin's utility as a store of value is dependent on its utility as a medium of exchange. We base this in turn on the assumption that for something to be used as a store of value it needs to have some intrinsic value, and if Bitcoin does not achieve success as a medium of exchange, it will have no practical utility and thus no intrinsic value and won't be appealing as a store of value. Like fiat currencies, Bitcoin is not backed by any physical commodity or precious metal.

Bitcoin has exhibited characteristics of a bubble with drastic price run-ups and a craze of media attention. This is likely to decline as Bitcoin continues to see greater mainstream adoption, but the future is uncertain.

Bitcoin's utility and transferability are challenged by difficulties surrounding the cryptocurrency storage and exchange spaces. In recent years, digital currency exchanges have been plagued by hacks, thefts and fraud. In those cases, however, regulation is much more settled, providing somewhat more straightforward means of redress. Bitcoin and cryptocurrencies more broadly are still viewed as more of a "Wild West" setting when it comes to regulation.

This article will not make a case for what the market penetration will be, but for the sake of the evaluation, we'll pick a rather arbitrary value of 15 percent, both for bitcoin as a currency and bitcoin as a store of value. You are encouraged to form your own opinion for this projection and adjust the valuation accordingly.

The predominant medium of exchange is government backed money , and for our model we will focus solely on them. Roughly speaking, M1 which includes M0 is currently worth about 4. M3 which includes all the other buckets minus M1 is worth about 45 trillion U. To this, we will also add an estimate for the worldwide value of gold held as a store of value.

While some may use jewelry as a store of value, for our model we will only consider gold bullion. The U.

Since there has in recent years been a deficit in the supply of silver and governments have been selling significant amounts of their silver bullion , we reason that most silver is being used in industry and not as a store of value, and will not include silver in our model. In aggregate, our estimate for the global value of stores of value comparable to bitcoin, including savings accounts, small and large time deposits, money market funds, and gold bullion, come to If Bitcoin were to achieve 15 percent of this valuation, its market capitalization in today's money would be This is a rather simple long term model.

Perhaps the biggest question it hinges on is exactly how much adoption will Bitcoin achieve? Coming up with a value for the current price of Bitcoin would involve pricing in the risk of low adoption or failure of Bitcoin as a currency, which could include being displaced by one or more other digital currencies. Models often consider the velocity of money, frequently arguing that since Bitcoin can support transfers that take less than an hour, the velocity of money in the future Bitcoin ecosystem will be higher than the current average velocity of money.

Another view on this though would be that velocity of money is not restricted by today's payment rails in any significant way and that its main determinant is the need or willingness of people to transact. Therefore, the projected velocity of money could be treated as roughly equal to its current value.

Another angle at modeling the price of Bitcoin, and perhaps a useful one for the near-to-medium term, would be to look at specific industries or markets one thinks it could impact or disrupt and think about how much of that market could end up using Bitcoin.
