Just a few short years ago, buying up cryptocurrency was all the rage. In theory, you could spend a little on Bitcoin or one of the other popular cryptocurrencies, and cash out with an astonishing rate of return.

It’s kind of a random pairing—I get it—but two new websites have joined ‘have i been pwned’s’ illustrious list of breached sites. One is a cryptocurrency wallet and the other is a RuneScape bot. These sound like small potatoes, but the two breaches have potentially affected up to 2.2 million users, and you’d be wise to do some checking (and changing) if you think you might fall into either group.

Libra season is over. On October 24, Facebook founder and Turing Test dropout Mark Zuckerberg testified to U.S. Congress for five hours about the cryptocurrency that Facebook wants to launch next year — but which now might never launch at all. Here’s what went down.

While we’re still waiting on a specific release date for Facebook’s upcoming cryptocurrency, Libra, the company is aiming for an early 2020 release. That gives you plenty of time to find bugs in the currency’s infrastructure — a project that could reward you handsomely.

Libra hasn’t even officially debuted on Facebook yet, but the highly anticipated cryptocurrency has already gotten a ton of interest - from scammers. In fact, it’s hard to tell who is more interested in Libra at this point: those looking to make a quick buck from cajoling you to jump in early so you can be a Bitcoin-esqe billionaire, or federal regulators who have plenty of concerns about Facebook’s track record with, well, everything.

On Wednesday, Facebook announced Libra, a cryptocurrency that it will launch (along with 27 other partners) in 2020.

A little like Bitcoin and a little like PayPal, Libra will be a new digital currency, one available to people without bank accounts or credit cards, but that could potentially be a major force for the rest of us, too. But first you have to trust Facebook with yet more personal data. Here’s what you need to know.

It's official, Facebook's making its own currency. The social network recently unveiled Libra, the secretive cryptocurrency it's been working on for more than a year. The currency is being backed by investment from big payment companies like Mastercard, Visa, and PayPal, as well as tech giants including Uber and Spotify. Here's everything you need to know.

Although the cryptocurrency markets are already a volatile and relatively risky platform, spare a thought for folks who trusted Canadian exchange QuadrigaCX. The exchange kept a large portion of user funds in an offline cold wallet but the the password for that wallet was held by a single person who died, locking up about US$190M.

The ATO has reissued warnings to cryptocurrency traders, reminding them that it will be keeping a close eye on their profit reporting. If you cashed in a windfall and failed to declare it - watch out.

In 2017, Bitcoin's value soared from $1200 to around $25,000 before dropping down to around $16,000 at the end of the year. Since then, it's value has risen and dropped sporadically from day to day, dragging smaller cryptocurrencies such as Ether and Ripple along with it.

Early this year, I decided to set up a cryptocurrency investment portfolio, using money I could afford to lose. Since then, the total value of my portfolio has fallen by 60 per cent. Here's why I'm holding on - and why you might want to consider buying bitcoin while prices are cheap. (Emphasis on 'might'.)

Bitcoin's price dropped sharply overnight, twice falling below $5000 per coin. At 6.30am AEDT, the benchmark cryptocurrency was trading lower by around 11.5% at $US4990. The collapse is being described by analysts as "like a house of cards." Yikes. Here are the details.

A mysterious, anonymous entity known as “Satoshi Nakamoto” posted a white paper on October 31 2008 entitled “Bitcoin: A Peer-to-Peer Electronic Cash System”. It was the first time that the concept of Bitcoin entered the world.

A 'stablecoin' is a cryptocurrency that's price is pegged to a real-world asset like gold or the dollar. Here's a guide to what they're used for, how they work, and why people are excited about them.

As the cost to mine cryptocurrencies continues to increase, people are looking for ways to boost their mining bang for buck. With energy costs rising, it actually costs more to mine many coins than their current face value. As a result, some recent data points to cryptojacking software - that mines for cryptocurrencies without your consent or knowledge - becoming increasingly prevalent and impacting about a quarter of businesses in the ANZ region. What can you do about it.

Cryptocurrencies are either going to be the biggest investment opportunity of the 21st century or represent the biggest financial fraud in history depending on who you ask. Almost everything you read about cryptocurrencies is focused on one particular coin; Bitcoin. Currently trading at around US$6600, is the price set to plummet or could it reach reach $50,000 or even $100,000?

So you're ready to buy some cryptocurrency. Maybe you've been reading up on blockchain technology and you're convinced it really is the future. Or maybe you watched a friend get rich off Bitcoin and you're still kicking yourself for not doing the same.

Video: We've already told you how to buy Bitcoin and other cryptocurrencies. But should you?

I've lost almost $400,000 worth of bitcoin so far. Now's the bit where I'm supposed to tell you it's all fake and I only lost it in the cryptocurrency trading simulation game Bitcoin Flip. But no, I actually bought $500 worth of bitcoin back when it was cheap, then left it in the hands of the Mt. Gox online exchange, which then lost it.
