Wij’re guessing: yes, you have. The very first and most famous digital cryptocurrency has bot racking up headlines due to a breathtaking rise ter value — cracking the $1,000 threshold for the very first time on Jan. 1, 2018, topping $Nineteen,000 te December of that year and then shedding about 50 procent of its value during the very first part of 2018.
But the Bitcoin story has so much more to it than just headline-grabbing pricing swings. It incorporates technology, currency, math, economics and social dynamics. It’s multifaceted, very 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.
But very first: A quick backstory
Bitcoin wasgoed invented ter 2009 by a person (or group) who called himself Satoshi Nakamoto. His stated aim wasgoed to create “a fresh electronic specie system” that wasgoed “fully decentralized with no server or central authority.” After cultivating the concept and technology, te 2011, Nakamoto turned overheen the source code and domains to others ter the bitcoin community, and subsequently vanished. (Check out the Fresh Yorker’s superb profile of Nakamoto from 2011.)
It’s actually a little more complicated than that.
What is bitcoin?
Simply waterput, bitcoin is a digital currency. No bills to print or coins to mint. It’s decentralized — there’s no government, institution (like a canap) or other authority that controls it. Owners are anonymous, instead of using names, tax IDs, or social security numbers, bitcoin connects buyers and sellers through encryption keys. And it isn’t issued from the top down like traditional currency, rather, bitcoin is “mined” by powerful computers connected to the internet.
How does one ‘mine’ bitcoin?
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 overheen a certain period of time, ter a “block.” Computers running special software — the “miners” — inscribe thesis transactions ter a gigantic digital ledger. Thesis blocks are known, collectively, spil the “blockchain” — an eternal, openly accessible record of all the transactions that have everzwijn bot made.
Using specialized software and increasingly powerful (and energy-intensive) hardware, miners convert thesis blocks into sequences of code, known spil a “hash.” This is somewhat more dramatic than it sounds, producing a hash requires serious computational power, and thousands of miners challenge at the same time to do it. It’s like thousands of chefs feverishly racing to prepare a fresh, utterly complicated dish — and only the very first one to serve up a volmaakt version of it completes up getting paid.
When a fresh hash is generated, it’s placed at the end of the blockchain, which is then publicly updated and propagated. For his or hier trouble, the miner presently gets 12.Five bitcoins — which, te February 2018, is worth harshly $100,000. Note that the amount of awarded bitcoins decreases overheen time.
What determines the value of a bitcoin?
Ultimately, the value of a bitcoin is determined by what people will pay for it. Ter this way, there’s a similarity to how stocks are priced.
The protocol established by Satoshi Nakamoto dictates that only 21 million bitcoins can everzwijn be mined — about 12 million have bot 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.
No, they’re not bitcoins. They’re pistachios.

Without a government or central authority at the hoofdbescherming, controlling supply, “value” is totally open to interpretation. This process of “price discovery,” the primary driver of volatility te bitcoin’s price, also invites speculation (don’t mortgage your house to buy bitcoin) and manipulation (hence the latest talk of tulips and bubbles).
Bitcoin has made Satoshi Nakamoto a billionaire many times overheen, at least on paper. It’s minted slew of millionaires among the technological pioneers, investors and early bitcoin miners. The Winklevoss twins, who parlayed a $65 million Facebook payout into a venture capital fund that made early investments ter bitcoin , are now billionaires according to Fortune.
How do I buy bitcoin?
If you’re willing to assume the risk associated with wielding bitcoin, there is an enlargening number of digital currency exchanges like Coinmama, CEX, Losbreken and Coinbase — the largest and most established of them — where you can buy, sell and store bitcoins.
Getting embarked is about spil complicated spil setting up a Paypal account. With Coinbase, for example, you can use your bankgebouw (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.
What can I do with bitcoin?
You can use bitcoin to buy things from more than 100,000 merchants, tho’ still few major ones. You can sell it. Or you can just suspend on to it. Note that there are no inherent transaction fees with bitcoin, albeit exchanges like Coinbase typically charge a toverfee when you buy or sell.
Is all of this legal?
The former Silk Road homepage.
Brief, qualified reaction: Yes, for now, spil long spil — like any currency — you don’t do illegal things with it. For example, bitcoin wasgoed the foot currency accepted on Silk Road, the Dark Web marketplace for drugs and other illicit goods and services that wasgoed shuttered by the FBI ter 2013 .
Since then, bitcoin has largely evaded regulation and law enforcement ter the US, albeit it’s under enlargened scrutiny spil it attracts more mainstream attention. Tho’ it’s legal to buy and sell bitcoin, miners and exchanges occupy a gray area that could be vulnerable to future regulation and/or law enforcement activity.
What are the risks?
Legal and regulatory hazards aside, spil both an investment and currency, bitcoin is very risky. When you wake up ter the morning, you know pretty precisely how much a dollar can buy. The financial value of a bitcoin, however, is very volatile and may sway widely from day to day and even hour to hour. ( Exhibit A: December 2018. )
Bitcoin transactions cannot be traced back individuals — they are secured but also obscured through the use of public and private encryption keys . This anonymity can be appealing, especially with companies and marketers increasingly tracking our every purchase, but it also comes with drawbacks. You can never be certain who is selling you bitcoin or buying them from you. Opportunities for money laundering abound, ter 2016, authorities ter the Netherlands arrested Ten guys for just this.
Theft is also a risk. The bitcoin subreddit is rife with individuals’ stories and even established exchanges are targets. Mt. Gox, based ter Japan, “lost” 750,000 of its customers’ bitcoins te 2014 and hackers took $60 million from NiceHash te December 2018. There are few avenues for pursuing refunds, challenging a transaction or recovering such losses. Once a transaction hits the blockchain, it’s final.
Coinbase has bot tested by a massive rise ter rente te bitcoin.
OK, so what about — wait, there are more risks?
Because bitcoin is so fresh and decentralized, there is slew of murkiness and many unknowns. Even the technical rules for mining are still evolving and up for debate.
The IRS views bitcoins spil property, not currency. There are tax implications and a federal judge recently ruled that Coinbase vereiste capitulate records to the IRS on transactions of $20,000 or more.
Then there’s the fundamental question of whether you should trust a particular exchange. Even Coinbase, the most established of them all has struggled to keep up with request, plagued by webpagina outages, scaling issues and customer service complaints. Even if it’s venture-backed, every bitcoin player today is by definition a startup and comes with all of the associated risks.
Now I sort of understand bitcoin. WTF is Bitcoin Specie?
Ter August 2018, different sects within the bitcoin mining community had a disagreement about the rules governing the mining process — specifically, what constitutes the adequate size (ter megabytes) of a block. Incapable to form a overeenstemming, there wasgoed a fork te the blockchain , with the bitcoin originalists going one way and the group favoring larger blocks going another to embark Bitcoin Metselspecie.
However they share a common digital ancestry, each now has its own individual blockchain with slightly different protocols. (For what it’s worth, bitcoin miners are sticking with 1MB blocks, Bitcoin Metselspecie uses 8MB blocks.) Forking is almost assured to toebijten again te the future.
Are there other cryptocurrencies?
Yes. More than a thousand, with more sprouting up every day. Aside from bitcoin, which is the real progenitor of them all, other well-known alternative currencies include Ethereum, Ripple and Litecoin. Wij take a look at the pros and cons of each, and how they stack up, ter this explainer .
