Currently, unless you're spending thousands of dollars to buy it in bulk, bitcoin is nothing more than a stock, though the inventors would hate to have it explained that way. In time, it could become a reasonable mean of purchasing goods and services—Japan accepts it now, legally. But for now, it's quite literally an investment. And if you're smart or lucky it can make you money, assuming the bubble doesn't burst. Cryptocurrency can be volatile, growing and plummeting in terms of value every day.

No one knows who created it — most cryptocurrencies are designed for maximum anonymity — but bitcoins first appeared in from a developer reportedly named Satoshi Nakamoto. He has since disappeared and left behind a bitcoin fortune.
Because bitcoin was the first major cryptocurrency, all digital currencies created since then are called altcoins, or alternative coins. Litecoin , Peercoin , Feathercoin , Ethereum , and hundreds of other coins are all altcoins because they are not bitcoin. One of the advantages of bitcoin is that it can be stored offline on local hardware, such as a secure hard drive.
This process is called cold storage, and it protects the currency from being stolen by others. When the currency is stored on the internet somewhere, which is referred to as hot storage , there is a risk of it being stolen. On the flip side, if a person loses access to the hardware that contains the bitcoins, the currency is gone forever. Various events turned bitcoin into a media sensation.
From to , criminal traders made bitcoins famous by buying them in batches of millions of dollars so they could move money outside of the eyes of law enforcement and tax collectors.
Subsequently, the value of bitcoins skyrocketed. Scams , too, are very real in the cryptocurrency world. Naive and savvy investors alike can lose hundreds or thousands of dollars to scams. Bitcoins and altcoins are controversial because they take the power of issuing money away from central banks and give it to the general public. Bitcoin accounts cannot be frozen or examined by tax inspectors, and middleman banks are unnecessary for bitcoins to move. Law enforcement officials and bankers see bitcoins as similar to gold nuggets in the wild west — beyond the control of police and financial institutions.
Once bitcoins are owned by a person, they behave like physical gold coins. They possess value and trade just as if they were nuggets of gold. Bitcoins can be used to purchase goods and services online with businesses that accept them or can be tucked away in the hope that their value increases over time.
Bitcoins are traded from one personal wallet to another. A wallet is a small personal database that is stored on a computer drive, smartphone , tablet, or in the cloud. Bitcoins are forgery-resistant because multiple computers, called nodes, on the network must confirm the validity of every transaction.
It is so computationally intensive to create a bitcoin that it isn't financially worth it for counterfeiters to manipulate the system. A single bitcoin varies in value daily. Check places like Coindesk to see current par rates. Bitcoins will stop being created when the total number reaches 21 billion coins, which is estimated to be sometime around the year By , more than half of those bitcoins had been created. The currency is self-contained and uncollateralized, meaning there's no precious metal behind the bitcoins.
The value of each bitcoin resides within the bitcoin itself. Bitcoins are stewarded by miners, the network of people who contribute their personal computer resources to the bitcoin network. Miners act as ledger keepers and auditors for all bitcoin transactions. Miners are paid for their accounting work by earning new bitcoins for the amount of resources they contribute to the network. Each blockchain is unique to each user and the user's personal bitcoin wallet.
All bitcoin transactions are logged and made available in a public ledger, which ensures their authenticity and prevents fraud. This process prevents transactions from being duplicated and people from copying bitcoins.
While every bitcoin records the digital address of every wallet it touches, the bitcoin system does not record the names of the people who own wallets. In practical terms, this means that every bitcoin transaction is digitally confirmed but is completely anonymous at the same time. So, although people cannot easily see the personal identity or the details of the transaction, they can see the verified financial history of a bitcoin wallet.
This is a good thing, as a public history adds transparency and security to every transaction. Bitcoin mining involves commanding a home computer to work around the clock to solve proof-of-work problems computationally intensive math problems. Each bitcoin math problem has a set of possible digit solutions. A desktop computer, if it works nonstop, might be able to solve one bitcoin problem in two to three days, however, it might take longer.
A single personal computer that mines bitcoins may earn 50 cents to 75 cents per day, minus electricity costs. Bitcoin mining is profitable only for those who run multiple computers with high-performance video processing cards and who join a group of miners to combine hardware power. This prohibitive hardware requirement is one of the biggest security measures that deter people from trying to manipulate the bitcoin system. People who take reasonable precautions are safe from having their personal bitcoin caches stolen by hackers.
There are two main security vulnerabilities when it comes to bitcoin:. More than hacker intrusion, the real loss risk with bitcoin revolves around not backing up a wallet with a fail-safe copy. There is an important.
