What is the purpose of bitcoin algorithmBitcoin explained: Here's everything you need to know - CNET
It's multifaceted, highly technical and still very much evolving. This explainer is meant to clarify some of the fundamental concepts and provide answers to some basic bitcoin questions. Bitcoin was invented in by a person or group who called himself Satoshi Nakamoto.
Check out the New Yorker's great profile of Nakamoto from Simply put, bitcoin is a digital currency. No bills to print or coins to mint. It's decentralized -- there's no government, institution like a bank or other authority that controls it. And it isn't issued from the top down like traditional currency; rather, bitcoin is "mined" by powerful computers connected to the internet. A person or group, or company mines bitcoin by doing a combination of advanced math and record-keeping.
Here's how it works. When someone sends a bitcoin to someone else, the network records that transaction, and all of the others made over a certain period of time, in a "block. These blocks are known, collectively, as the "blockchain" -- an eternal, openly accessible record of all the transactions that have ever been made.
Read: Blockchain explained -- it builds trust when you need it most. Using specialized software and increasingly powerful and energy-intensive hardware, miners convert these blocks into sequences of code, known as a "hash.
It's like thousands of chefs feverishly racing to prepare a new, extremely complicated dish -- and only the first one to serve up a perfect version of it ends up getting paid. When a new hash is generated, it's placed at the end of the blockchain, which is then publicly updated and propagated.
For his or her trouble, the miner currently gets Note that the amount of awarded bitcoins decreases over time. Ultimately, the value of a bitcoin is determined by what people will pay for it.
In this way, there's a similarity to how stocks are priced. The protocol established by Satoshi Nakamoto dictates that only 21 million bitcoins can ever be mined -- about 12 million have been mined so far -- so there is a limited supply, like with gold and other precious metals, but no real intrinsic value. There are numerous mathematical and economic theories about why Nakamoto chose the number 21 million. This makes bitcoin different from stocks, which usually have some relationship to a company's actual or potential earnings.
Without a government or central authority at the helm, controlling supply, "value" is totally open to interpretation. This process of "price discovery," the primary driver of volatility in bitcoin's price, also invites speculation don't mortgage your house to buy bitcoin and manipulation hence the recent talk of tulips and bubbles. Bitcoin has made Satoshi Nakamoto a billionaire many times over, at least on paper.
It's minted plenty of millionaires among the technological pioneers, investors and early bitcoin miners. If you're willing to assume the risk associated with owning bitcoin, there is an increasing number of digital currency exchanges like Coinmama, CEX, Kraken and Coinbase -- the largest and most established of them -- where you can buy, sell and store bitcoins.
Getting started is about as complicated as setting up a Paypal account. With Coinbase, for example, you can use your bank or Paypal account to make a deposit into a virtual wallet, of which there are many to choose from. Once your account is funded, which usually takes a few days, you can then exchange traditional currency for bitcoin. You can sell it. Or you can just hang on to it. Note that there are no inherent transaction fees with bitcoin, although exchanges like Coinbase typically charge a fee when you buy or sell.
Short, qualified answer: Yes, for now, as long as -- like any currency -- you don't do illegal things with it. For instance, bitcoin was the sole currency accepted on Silk Road, the Dark Web marketplace for drugs and other illicit goods and services that was shuttered by the FBI in Since then, bitcoin has largely evaded regulation and law enforcement in the US, although it's under increased scrutiny as it attracts more mainstream attention.
Legal and regulatory hazards aside, as both an investment and currency, bitcoin is very risky. When you wake up in the morning, you know pretty precisely how much a dollar can buy.
The financial value of a bitcoin, however, is highly volatile and may swing widely from day to day and even hour to hour. Exhibit A: December Currently, a winner is rewarded with The wallet is a kind of virtual bank account that allows users to send or receive bitcoins, pay for goods or save their money. Unlike bank accounts, bitcoin wallets are not insured by the FDIC. Wallet in cloud: Servers have been hacked.
Wallet on computer: You can accidentally delete them. Viruses could destroy them. Though each bitcoin transaction is recorded in a public log, names of buyers and sellers are never revealed — only their wallet IDs. No one knows what will become of bitcoin. It is mostly unregulated, but some countries like Japan, China and Australia have begun weighing regulations.
Governments are concerned about taxation and their lack of control over the currency. Why bitcoin? Transfers People can send bitcoins to each other using mobile apps or their computers.
