After peaking at just over $20,000, Bitcoin entered a massive correction last year which took it dangerously close to the $10,000 mark. The most-valuable cryptocurrency looked like it could recover for a while, but today it is still far, far away from the record price of last year.

The correction is moving Bitcoin back into sub-$10,000 territory today, and it is taking the market down along with it. Some of the majors are still holding well, but the top 100 is in the red almost in its entirety.

Facebook has announced a new advertising policy which ban ads for cryptocurrencies such as Bitcoin. The ban also applies to ICOs because they are "frequently associated with misleading or deceptive promotional practices."

The social network says that the new policy is a part of a drive to improve the "integrity and security of financial product and services ads," but it explains that it is keeping its guidelines "intentionally broad" to start with.

Bitcoin remains one of the hottest financial topics of the last several years. The digital currency grew from less than $1,000 per coin at the start of 2017, to nearly $20,000 by the end of the year.

The buzz around Bitcoin continues to grow despite high volatility -- including a 50 percent drop between December and January -- and condemnation from figures like Warren Buffet who call it a "fraud." But how is it being used? And most important, what value does it really hold as an investment?

The clandestine mining of cryptocurrency is something that we have seen in various forms over the last year or so, in website code and Android apps. A new discovery by security firm Trend Micro shows that hackers have found a way to inject Coinhive mining code into ads that appear on YouTube.

The crypto-jacking technique means that hackers have been able to profit by using other people's CPU time to mine the Monero cryptocurrency while they watch videos. Trend Micro reports that there has been a huge increase in Coinhive web miner detections in recent days, with hackers abusing Google's DoubleClick to distribute the code through big sites including YouTube.

2017 was a wild ride for cryptocurrencies and for Bitcoin in particular, rising in price at one point above $19,000 only to drop back to a bit over half of that number now. But which number is correct? If only the market can tell for sure -- and these numbers are coming straight from the market, remember -- what the heck does it all mean? It means Bitcoin isn’t a currency at all but traders are pretending that it is. 2018 will see investors finally figure this out.

Confusion abounds, so let’s cut through the crap with an analogy. Cryptocurrencies like Bitcoin, Ethereum and a ton of others operate almost exactly like a market that uses only U.S. one dollar bills and doesn’t allow exchanging those bills… ever. If you need five dollars, that will be five one dollar bill, please. If you need less than a dollar then you and your counter-party have to agree how much of a one dollar bill you each own. And they aren’t just any one dollar bills: they are specific bills, each with its own unique serial number that can be checked against a U.S. Treasury database to make sure the money is real -- that it is actually worth a dollar.

BitFlyer, one of the largest cryptocurrency exchanges in the world, is now available in Europe, after receiving a license to operate in the EU. The Japan-based company, which has a daily volume in excess of $260 million, claims that it's "the most compliant virtual currency exchange in the world," as a result.

BitFlyer first opened its doors to Japanese crypto enthusiasts and expanded in the US last year. In 2017, it reached a volume of over $250billion from cryptocurrency trades, mainly in Bitcoin.

A new correction is taking place in the crypto market, after South Korea and China indicated that they could introduce new regulations to crack down on investments and centralized trading, respectively.

South Korea is one of the biggest cryptocurrency markets, being responsible for a large part of the daily volume for the major coins and home to some of the most important exchanges, like Upbit and Bithumb.

The Bitcoin bubble means there is a massive interest in cryptocurrencies, particularly from those looking for an easy way to make a quick buck. It's also led to secretive mining tools making use of people's CPUs without their knowledge, mining for profitable cryptocurrency for persons unknown.

We've seen this with both websites and browser extensions, and now a security researcher has discovered a series of fake Android apps harboring an undisclosed Coinhive cryptocurrency miner. The repackaged APKs take advantage of the CPUs of the smartphones the apps are installed on.

Microsoft has had something of an on-off relationship with Bitcoin over the years, and once again the Windows-maker has chosen to drop support for the cryptocurrency -- at least temporarily.

It has been reported that Microsoft is uncomfortable with the fluctuating value of Bitcoin, as well as the increased transaction fees. As such, customers will no longer be able to add to their Microsoft account balances using Bitcoin.

With the popularity of Bitcoin and other cryptocurrencies, it's perhaps little surprise that a number of websites have recently been discovered using visitors' computer to do a little mining. The latest site found to be indulging in the activity is BlackBerry Mobile -- but this time it's thanks to the work of a hacker.

As with other sites carrying out surreptitious mining, it was a CoinHive mining tool that was found embedded in the code of the site. The same hacker also placed the same miner on a handful of other sites.

Opera may not be the most popular web browser, but it is certainly one of the most feature-full offerings. Quite frankly, it is actually quite good, and if you haven't tried it recently, you should. Not to mention, it is very much a cross-platform affair, offering versions for Windows, macOS, Linux desktop, Android, iOS, and more.

The upcoming version 50 of the Opera web browser is particularly intriguing. Why? Well, it will offer a really cool integrated anti-Bitcoin mining feature. Besides Bitcoin, it will also block the mining of other cryptocurrencies such as Litecoin and Ethereum. If you aren't aware, some websites are hijacking user computers to mine for cryptocurrencies. This is not only a potential violation of trust, but it can negatively impact the computer's performance too. Mining is also a huge waste of electricity. Opera 50 will offer an optional setting that, when enabled, blocks this nonsense.

The cryptocurrency market has been on a tear this year, shattering record after record. Fueled by majors like Bitcoin, Ethereum, Ripple and Bitcoin Cash, it reached an incredible valuation on December 21: $654 billion. However, after the peak comes the fall, and here the crashes tend to be swift and massive.

Case in point: the cryptocurrency market is now down by more than $230 billion from yesterday's high. And, yes, you are reading that right. Its capitalization is currently hovering around the $422 billion mark. All the majors (top 10) are down by double digits in the past 24 hours, with Bitcoin suffering the smallest loss at 27.05 percent, as are nearly all the other coins in the top.

Coinbase is one of the largest cryptocurrency exchanges in the world, so when it adds a new coin to its portfolio investors take notice. It is not uncommon for the price to see a big jump as a result: Litecoin, for instance, gained over 50 percent following the listing on Coinbase.

Something similar happened yesterday when Coinbase finally added Bitcoin Cash to the platform. At opening, the coin was trading for $2,200. The announcement saw the price rising to $2,805 at closing. However, on GDAX (Coinbase's trading platform), it simply exploded, which has lead Coinbase to consider the possibility of insider trading.

Litecoin is one of the strongest performers in the cryptocurrency market in 2017. In the past three months its price has increased from $51 to $361, gaining over 500 percent. However, the gains are even higher since January 1 -- 8,200 percent at peak value just a few days ago. Trading opened at $4.33 on the first day of the year.

The stellar performance has attracted an interesting response from Litecoin founder Charlie Lee, who, against the norm in the crypto scene, advised people to "invest responsibly" and warned of a consolidation. That has yet to happen, at least to the extent of a deep correction like we have seen this year, but it looks like Lee will not be financially involved in LTC then, as he's sold (and "donated") all of his LTC coins.

It's fair to say that, in its current state, Bitcoin does not work as a means of payment for basic things. The average transaction fee is over $20, which makes common purchases, like a cup of coffee, virtually impossible to justify. However, as I noted in my What can you buy with Bitcoin? piece, things are different when we are looking at very expensive purchases.

One such scenario where using Bitcoin makes a whole lot of sense is buying a home. The transaction fee is negligible, as the cost is in the hundreds of thousands of dollars, if we are looking at the median price of a US home.
