What is a bitcoin & how is it used

What Is Bitcoin, and How Does It Work? - NerdWallet

Bitcoins can be stored in two kinds of digital wallets:. Hot wallet: Digital currency is stored in the cloud on a trusted exchange or provider, and accessed through a computer browser, desktop or smartphone app. Cold wallet: An encrypted portable device much like a thumb drive that allows you to download and carry your bitcoins.

Basically, a hot wallet is connected to the internet; a cold wallet is not. But you need a hot wallet to download bitcoins into a portable cold wallet. Price volatility. Hacking concerns. While backers say the blockchain technology behind bitcoin is even more secure than traditional electronic money transfers, bitcoin hot wallets have been an attractive target for hackers. Limited but growing use. But these companies are the exception, not the rule.

Not protected by SIPC. Private, secure transactions anytime — with fewer potential fees. Once you own bitcoins, you can transfer them anytime, anywhere, reducing the time and potential expense of any transaction.

The potential for big growth. The ability to avoid traditional banks or government intermediaries. After the financial crisis and the Great Recession, some investors are eager to embrace an alternative, decentralized currency — one that is essentially outside the control of regular banks, governing authorities or other third parties.

However, to buy Bitcoin on an exchange with U. There are four ways to get bitcoins:. Cryptocurrency exchanges. Simply put, if one day a large number of merchants who accept bitcoin as a form of payment stop doing so, then the value of bitcoin would fall drastically. The current high value of Bitcoin is a function of both the relative scarcity of Bitcoins themselves and its popularity as a means of investment and wealth generation. If confidence in the Bitcoin market is suddenly and drastically reduced—for example, if a major government declared Bitcoin use illegal, or one of the largest Bitcoin exchanges was hacked and lost all of its stored value—the value of the currency will crash and investors will lose huge amounts of money.

The United States Treasury does not recognize bitcoin as a conventional currency, but does recognize its status as a commodity, like stocks and bonds. Similarly, the US Internal Revenue Service considers bitcoins property and taxes them as such if they are declared.

No other country has declared bitcoin to be a recognized currency, but engagement with bitcoin and other cryptocurrencies varies from place to place. Some countries are investigating bitcoin as a growing commodity market, some take the same stance as the US declaring them assets, and some have explicitly banned their use for transfer of goods or services though the means of enforcing those bans are limited. The Bitcoin network has no built-in protection mechanisms when it comes to accidental loss or theft.

For instance, if you lose the hard drive where your Bitcoin wallet file is stored think corruption or drive failure with no backup , the Bitcoins held in that wallet are lost forever to the entire economy. Interestingly, this is an aspect which further exacerbates the limited supply of Bitcoins.

Additionally, if your wallet file is stolen or compromised and the Bitcoins contained within it are spent by the thief before the rightful owner, the double spending protection mechanism built into the network means the rightful owner has no recourse. Unlike if, for example, your credit card is stolen, you can call the bank and cancel the card, bitcoin has no such authority. The Bitcoin network only knows that the bitcoins in the compromised wallet file are valid and processes them accordingly.

Bitcoin markets are vulnerable to attack or fraud. Major exchanges like GBH and Cryptsy have been shut down with all the Bitcoin entrusted to their care presumably stolen by the operators.

Japan-based Mt. Gox, formerly the handler of over half the Bitcoin transactions on the planet, was shuttered after a theft of hundreds of thousands of Bitcoins. The incident caused a huge but temporary drop in the value of Bitcoin worldwide.

The Bitcoin block system requires connection and confirmation from the peer-to-peer network to be verified. As more and more vendors and individuals use Bitcoin to do business, the number of transactions per second increase, and the peer-to-peer network is becoming congested, with some operations without transaction fees taking hours to clear.

A central principle to the design of the Bitcoin system is that there is no single transactional processing authority. As a result, no single user can be locked out of the system. Combine this with the inherent anonymity of transactions, and you have an ideal medium of exchange for nefarious purposes. Bitcoin has become an ideal means for commerce in illicit goods and services.

The quintessential case is the Silk Road , a dark web site that allowed users to anonymously trade items like drugs and fake identification, all bought with Bitcoin thanks to its untraceable nature. Satoshi Nakamoto could be an individual man or woman, an internet handle, or a group of people, but nobody actually knows. Once their work of designing the Bitcoin network was complete, this person or persons essentially disappeared.

Whoever he, she, or they are, Satoshi Nakamoto is estimated to be in possession of billions of US dollars worth of Bitcoin at current market rates. Many experts in standard money markets and investments consider Bitcoin a poor choice for investing money. The extreme volatility of Bitcoin versus investments like stocks, bonds, and standard commodities makes larger and older institutions wary.

As stated above, use caution when dealing in Bitcoin either as a means of purchasing goods or services or investing. On August 1st, , long debates between bitcoin proponents and disagreements on how to solve its problems resulted in a currency split. The Bitcoin standard was broken in two, with the original system unaffected and the new Bitcoin Cash standard added. This was less like a stock market split and more like a software fork. Every person or organization who owned Bitcoin in any amount immediately owned an equal amount of Bitcoin Cash, with sales and transfers of both currencies occurring normally after the split.

Like the original Bitcoin, Bitcoin Cash is entirely digital and has no real-world physical component despite the name. The split is a hard fork in software terms. The separate Bitcoin Cash peer-to-peer system allows for eight times more transactions per block, making it a better but not necessarily equal competitor to credit and debit cards for constant online and in-person sales.
