You’ve very likely heard of the digital currency bitcoin. The notoriously volatile currency is regularly featured te the news spil the value of a single bitcoin swings inbetween $20,000 and $8,000 and major financial institutions announce that its time is up &mdash, or else that it will convert the way money works. A number of regulators around the world are beginning to lay down a framework for governing (or banning) bitcoin. Our handy guide is here to help you decipher exactly what bitcoin is, and whether you need any.

What is bitcoin?

Bitcoin is a digital currency &mdash, a virtual form of metselspecie &mdash, that permits users to make anonymous payments online. Bitcoin transactions are validated by a vast network of computers, instead of banks or governments, making it a decentralized form of money that many have hailed spil a privacy-friendly response to corporate banking and a recession-proof alternative to inflationary currencies.

Computers track and encrypt bitcoin transactions ter a process called mining, saving the gegevens te a record called a blockchain. Fresh bitcoins are created te the mining process. The bitcoin blockchain is a public ledger of every bitcoin transaction inbetween any two parties. Because it’s permanently validated by thousands of computers, this ledger is said to be virtually incorruptible, spil a hack would need to outstrip the combined processing power of every rekentuig working on the bitcoin blockchain.

What can I use bitcoins for?

Bitcoin wasgoed designed to transfer sums of money inbetween two strangers without the need for an intermediary to verify the validity of the transaction. This means you can pay another person directly online, without having to provide identifying details such spil a PayPal account or credit card information.

Because of bitcoin’s capability to facilitate anonymous purchases online, almost half of all bitcoin transactions are associated with illegal trade (think the type of black market activity found ter the murkier dark web of the internet).

Mainstream retailers from Microsoft to Expedia are opening their registers to bitcoin. Te theory, bitcoin could become a viable way to pay for things online without leaving the same type of trail a credit card leaves &mdash, and without adding to the in-depth profile advertisers have of what you like, buy and search for.

Its meteoric rises and falls have even waterput bitcoin on two major stock exchanges, spil U.S. regulators approved derivatives trading on bitcoin futures and interchanges (but not ongezouten ownership of bitcoin itself).

What’s the catch with using bitcoin?

The growing numbers of people transacting te bitcoin has slowed down the bitcoin network, spil it fights under the processing geyser. At points, this has enhanced transaction times from a few minutes to more than a day and raised transaction fees, making it a rather costly way to pick up that bitcoin bucket of KFC.

&quot,Bitcoin wasgoed not designed spil an everyday currency,&quot, says Lawrence H. White, economics professor at George Mason University and an pro on monetary policy. &quot,Spil it stands, it’s useful for occasional peer-to-peer remittances without the need for third-party verification.&quot,

Fresh payment processors such spil Lightning promise to increase the capacity for bitcoin transactions, which could facilitate the use of bitcoin for smaller purchases. That said, bitcoin isn’t a popular medium of exchange at the uur, partly due to its &quot,lack of a killer app,&quot, says White, which keeps the number of bitcoin spenders below a critical mass that might help keep its oscillating value steadier.

&quot,The volatility of bitcoin had bot declining before last year’s spike, but now it’s spil high spil it’s everzwijn bot,&quot, White says. &quot,The more people use it spil a medium of exchange, the more you would expect that to peaceful down &mdash, but people are not keen to hold on to bitcoin spil a payment method because it’s so volatile, so it’s a bit of a chicken-and-egg problem.&quot,

Financial institutions are also making it difficult to get bitcoin ter the very first place &mdash, Citigroup, Bankgebouw of America and JPMorgan Pursue are among the major U.S. credit card issuers banning purchases of bitcoin and other cryptocurrencies from known exchange platforms, making it tighter for first-timers to inject the bitcoin market.

Should I invest te bitcoin?

That depends on your appetite for risk. This hyper-volatile currency rose by almost 1,400% ter 2017 (before crashing to its current, relatively modest $8,400 vanaf bitcoin) &mdash, fantastic if you bought some a few years ago, less so if you bought at peak value. &quot,Nobody should waterput the large share of their retirement savings into bitcoin, but it does diversify your portfolio,&quot, White notes.

There’s also the fact that around 1,000 people are thought to hold 40% of the bitcoins ter circulation, which would make it possible for thesis big money players to manipulate the value of bitcoin &mdash, just spil a Tokyo bitcoin holder caused a slump by selling $400 million worth of bitcoin.

Unlike with real-world &mdash, government-supported &mdash, currency, there’s no assure that bitcoin will have any value te the coming years (or that it won’t). Many banks have denounced the &quot,bitcoin bubble,&quot, suggesting its market will collapse and the value of a bitcoin will fall to zero &mdash, however White doesn’t predict that will toebijten.

Should I mine bitcoin?

No. The scale of the computing equipment needed te the mining process to create fresh bitcoins is unfeasible for the average person, and the vast amounts of electro-therapy consumed are unlikely to make it worth your while.

When the very first bitcoins were mined te 2009, a private laptop could have turned out a duo of hundred bitcoins te a few days. That’s no longer possible, due to the escalating difficulty of the mining process, which requires increasingly more computing power spil the total number of bitcoins created approaches its supply cap of 21 million.

Today, 80% of bitcoins have bot mined and miners need customized equipments designed to do nothing but solve blocks of bitcoin problems. Spil an individual miner, you’d usually join compels with a pool of other miners, but this involves fees that cut into your profits.

How can I get bitcoins?

Very first, you’ll need a place to keep your bitcoins &mdash, a wallet. This wallet is a string of text that people can use to send you bitcoins. It’s a bit like a bankgebouw account number, the only difference is that it isn’t linked to any identifying information about you. Signing up for a wallet is spil effortless spil signing up for a fresh email account. All you need is an email address to receive a verification verbinding.

Wallets (that is, the strings of text identifying your bitcoin holdings) can be held online, offline ter &quot,cold storage&quot, hardware such spil a USB stick or even on paper (this more sophisticated method involves a lump of paper with a QR code that, when scanned, offers access to an online wallet). Keeping this wallet ID safe is critical &mdash, several billions of dollars’ worth of bitcoin is estimated to be lost through losing access to wallets, whether by throwing them out or misplacing details.

Blockchain is a popular, free wallet with 15 million users. It can be accessed via a web browser spil well spil Android and iOS apps. Unlike many others, it doesn’t require identification details (albeit you’ll be encouraged to add some to facilitate account recovery).

Because there’s always the possibility that a wallet can be hacked (like any other online account), if you intend to keep a large amount of bitcoin, it’s a good idea to store most of your haul te a cold-storage wallet.

Electrum is a newer, also free online wallet for desktop and Android, with a relatively easy-to-use interface and the option to save the bulk of your bitcoin stash offline te cold storage. (Spil of publishing, there had bot a security breach which has bot addressed.)

Ledger Nano S is a hardware option with wallet software on a USB stick that keeps your bitcoin securely offline and can cork into a pc to send or receive bitcoins instantly. A backup and recovery sheet contains your wallet details, so if you lose the stick, your coin is safe. Available for $98.99 at Amazon.

Where can I get bitcoins?

The easiest way to score some bitcoin is to head to a bitcoin exchange webpagina, of which there are dozens, based around the world. Bitcoin exchanges are a toneelpodium for buyers and sellers of bitcoin to conduct transactions, for a toverfee. San Francisco-based Coinbase is one of the best-known exchanges, and permits transactions inbetween bitcoin and your local currency, cashing out to your canap account or debit or credit card (if you use a canap that doesn’t geobsedeerd cryptocurrency purchases). You can also trade te two other digital currencies &mdash, ethereum and litecoin &mdash, spil well spil sign up for a Coinbase wallet for seamless trading on its exchange.

If you live ter the U.S., you might want to choose a U.S.-based coin exchange to avoid foreign transaction fees from your canap.

You’ll find that the value of a bitcoin varies somewhat across exchanges &mdash, this is due to the different request (from would-be buyers) and supply (from users holding bitcoin) on each exchange, and varying transaction fees.

There is also a puny number of bitcoin ATMs &mdash, about 1,600 ter the U.S. at press time &mdash, where you can withdraw contant from your debit account to a bitcoin wallet or deposit metselspecie spil bitcoin (ter other words, buy bitcoin).

Is bitcoin indeed anonymous?

You might have spotted a seeming contradiction above &mdash, how anonymous is using bitcoin if a wallet ID can be linked to a real-world canap account? The response is that bitcoin transactions often can be traced back to identifying details, especially spil more third-parties require credentials &mdash, such spil wallet providers and coin exchanges &mdash, spring up ter its nascent ecosystem.

Because all transactions are public ter the bitcoin blockchain, it’s also possible to track the payments made and received by a particular wallet and build a profile based on where bitcoins are spent, especially if they toebijten to be spent at a real-world retailer or cashed out to a canap account. Researchers at Princeton University found that the gegevens leaked through cookies and trackers by web retailers about bitcoin transactions could be sufficient to listig the transactions to buyers’ information such spil an email address.

Bottom line: Bitcoin is not 100% anonymous, tho’ the use of anonymous browsing contraptions can protect individual information when spending bitcoin.

How secure is bitcoin?

There are undoubtedly concerns about the security of bitcoin holdings. Hackers have attacked major bitcoin exchanges such spil Bitfinex and Mt. Gox, making off with millions of dollars’ worth of currency, leaving users bereft with no institutional backup.

Spil more people have bot getting ter on bitcoin &mdash, and other cryptocurrencies &mdash, there has also bot a rise ter attacks on investors’ wallets. For example, there have bot phishing attempts for login details and a particularly virulent phone-porting scam to attempt and build up control of users’ cryptocurrency accounts.

It’s imperative, therefore, to use a bitcoin wallet that requires at least one offline means of logging te, making it more difficult for online thieves to hack. &quot,Before trusting a bitcoin wallet with my bitcoins, I’d make sure it offers good encryption with second-factor authentication,&quot, says Sophos senior security advisor Chester Wisniewski. &quot,The less convenient it is to access, the more secure it generally is.&quot,

Unluckily, for now, there’s little protection against the losses incurred when bitcoin exchanges are hacked. (Nonetheless, some providers have bot klapper by lawsuits for losing their users’ metselspecie, after a 90-minute blackout at the world’s largest exchange, BitThumb, cost traders millions of dollars, users subsequently filed a class-action lawsuit.)

Does bitcoin have a future?

Central banks around the world, including te the U.S., have floated the idea of a government-backed digital currency &mdash, but it’s early days for bitcoin and other cryptocurrencies ter the eyes of the Federal Reserve, which noted that there were technical and privacy issues to overcome.

&quot,Bitcoin is not yet a money ter the standard sense of a commonly accepted medium of exchange &mdash, you can purchase a pretty limited set of things with bitcoin at present,&quot, White says. &quot,There is acknowledgment that the technology is remarkable and has potential uses, but it is too soon to tell whether further advances can make bitcoin a more user-friendly, everyday currency.&quot,
