In just four hours of early Saturday trading, the price of the cryptocurrency Bitcoin surged over 9% to a new record. At the time of this writing, one Bitcoin is valued at $3,169.90, well above the previous record of $3,000 set in June .

Bitcoin's total market value is now more that $52 billion, according to data from CoinMarketCap, and the return on Bitcoin investments made on January 1 st of this year stands at nearly 220%.

Bitcoin will almost certainly remain a highly volatile asset, but its latest high reflects a major positive development. After years of heated debate over how to increase the Bitcoin networks transaction capacity, major players have finally agreed on a compromise solution known as Segwit2x . That accomplishment is reassuring for those who may have begun to doubt the effectiveness of Bitcoins leaderless governance model .

The Segwit2x solution also seems to have driven Bitcoin's price higher in a less direct way. On Tuesday, a faction who disagreed with the proposal spun off a so-called fork of Bitcoin, known as Bitcoin Cash , which implemented a different fix. All holders of Bitcoin received matching Bitcoin Cash, which now trades as BCH on exchanges, and has a total current value of $3.75 billion.

However, the price of Bitcoin Cash has declined steadily over the last two days as Bitcoin and other major cryptocurrencies have surged. That suggests investors are cashing out of the upstart fork, which has sparse support from miners and exchanges, and pumping their gains back into older, more trusted, and more widely-adopted cryptocurrencies.

Bitcoin Rockets Past $3000 to a New Record High - Fortune

Bitcoin leaped more than 16 percent Saturday into record territory, significantly strengthening against its offshoot "bitcoin cash" amid a hack on the new currency's network.

Bitcoin hit an all-time high of $3,360.87 Saturday, according to CoinDesk, before paring its gains slightly to hover near $3,303, with a market capitalization of more than $54 billion.

The digital currency has now more than tripled in value for the year, and gained about 15 percent in the first few days of August. Bitcoin has broken free of the trading range it's held ever since reaching its prior record of $3,025 in mid-June.

Ari Paul, CIO of BlockTower Capital, attributed the gains to a relief rally after a "relatively uneventful" split, as well as new investors buying bitcoin.

"With SegWit activation and the hard fork in the rear view mirror, bitcoin buyers see a smooth road ahead for the next two months," he told CNBC in an email, referring to a more popular upgrade proposal called Segregated Witness.

Another digital currency, ethereum, climbed more than 12 percent to $250 Saturday afternoon, according to CoinDesk.

On Tuesday, Bitcoin split into bitcoin and bitcoin cash when a minority of developers went ahead with an alternative upgrade proposal. Investors holding bitcoin at the time of the split should have received an equal amount of bitcoin cash, and were able to trade it Tuesday. However, some major exchanges only began accepting bitcoin cash deposits Thursday and Friday.

ViaBTC, the Chinese exchange that's been the main proponent for bitcoin cash, tweeted at 4:03 a.m. that it temporarily suspended withdrawals due to a " transaction malleability attack" on the bitcoin cash network.

ViaBTC tweeted at 8:44 a.m. that it resumed withdrawals.

Bitcoin cash plunged nearly 36 percent Friday, falling about 9 percent to overnight to a low of $212. It recovered slightly to $223 Saturday afternoon, according to CoinMarketCap.

Bitcoin Magazine pointed out Saturday morning that ViaBTC mining activity which creates more of a digital currency for bitcoin cash dropped to a tenth of what it was in the last few days, while most of the mining activity was concentrated on the original bitcoin.

Bitcoin surges above $3K to record, more than tripling this year while 'bitcoin cash' struggles - CNBC

A group of Chinese cryptocurrency miners who use special software to solve math problems and get bitcoin in return, were longing for their own version of bitcoin. With a spin-off launched this week, they partially achieved their dream.

On Tuesday night, bitcoin cash, an alternative to blockchain technology-based bitcoin, made its debut. The split derived from a three-year civil war in the polarised bitcoin world over the technical direction in which the de-centralised cryptocurrency is going. Some see it as the inevitable outcome of irreconcilable conflicts between bitcoin developers, who maintain the bitcoin software, and miners, many of whom are based in China and use massive computing powers to generate the coin.

You have this one side, which is saying that we need to keep bitcoin as fast, cheap, and efficient as possible those are kind of people that want to be able to pay for coffee in bitcoin and they want bitcoins transaction speed to be better than [that of] credit cards, said Thomas Glucksman, head of marketing at Gatecoin, a Hong Kong-based bitcoin exchange.

But there is another camp, which is saying this is very early-stage technology. Lets maintain the security of the bitcoin network first, he said.

One of the biggest supporters of bitcoin cash is ViaBTC, a Shenzhen-based bitcoin startup founded in mid-2016 by Yang Haipo, who had worked as a programmer at tech giant Tencent on its cloud service and defunct Tencent Weibo, Chinas answer to Twitter.

Bitcoin bulls on the run, as value charges through the US$2,000 barrier

Yang is a die-hard advocate of turning bitcoin into a global payment system matching the power of conventional systems like Visa by expanding the capacity of a block, where bitcoin transactions are processed, from one megabyte to eight megabytes.

But critics of bitcoin cash, many of whom are bitcoin developers, argued such scaling would require more hardware and computing power and questioned whether the alternative would garner the popularity of bitcoin without confusing investors.

The rift is simply so wide that it led to the split, Yang said. Its a misunderstanding that we created bitcoin cash. But harbouring massive mining power in China does give prominence to our backing.

bitcoin cash, with similar bottom technology to bitcoin but with larger block sizes, can process about 30 transactions per second, four times more than bitcoin, though still a far cry from the thousands of transactions handled by Visa every second.

Today, China controls about 70 per cent of global computing power on bitcoin mining, thanks to cheap labour, hardware and electricity. Miners pooled at ViaBTC have close to six per cent.

Utility costs brought down by industrial overcapacity and a rising bitcoin price have made large-scale mining farms in China profitable and enabled them to elbow out their foreign counterparts in the market. Built near power stations in remote areas such as Xinjiang and Tibet, theses secretive server farms often feature a web of cables connecting thousands of mining machines that work around the clock under controlled cooling.

Bitcoin has been one of the best performing currencies this year, lately trading above US$2,700 per coin. It has attracted the savings of many Chinese investors, as assets with high investment returns remain scarce on the mainland.

Can Chinas central bank mint an answer to bitcoin?

Chinese authorities, meanwhile, keep a wary eye on the digital currency, and the countrys central bank has explicitly banned Chinese financial institutions from accepting bitcoin as a means of value. Meanwhile, the Peoples Bank of China is investing in developing a sovereign digital currency, although limited progress has been made in that endeavour.

When the split started on Tuesday night, bitcoins price plunged 11 per cent within two hours but later rebounded. The price of bitcoin cash has soared as much as 200 per cent to more than US$700 and now stands at around US$300.

The market is still cautious about the spin-offs future, which depends on how many exchanges allow it to trade and whether miners would dedicate their computing power to the new asset. Even in China, only few bitcoin exchanges have supported it in public.

Its also been a tough week for Yang and his team. Haters of bitcoin cash referred to it as B-cash in an attempt to cut its ties from bitcoin. On Thursday night, ViaBTCs website went dark briefly after suffering overwhelming traffic in what is known as a DDoS, or distributed denial of service, attack.

But Yang seemed to have prepared for it long time ago, as he wrote in a heated debate over bitcoin scaling on a Reddit forum thread eight months ago, Were not at all afraid of DDoS attacks. If you want to attack us, bring it on.

As the entire community has been laser-focused on the recent hard fork and Bitcoin network split, many people have forgotten about the Segwit2x plan. Miners who participated in the New York Agreement (NYA) have kept their promise and Segregated Witness will lock-in on the network in roughly two weeks.

Also read:Gwyneth Paltrow Joins Bitcoin Wallet Abra as Advisor

A few more changes are coming to the Bitcoin network in the near future. The Segwit2x plan often referred to as NYA is still following its course towards protocol activation of Segwit. At the time of writing, there are 621 blocks remaining for BIP 141 (Segwit) lock-in, and the plan seems to be running smoothly. The vast majority of miners who agreed to the Segwit2x proposal are still following through with at least half of the plan. The second half of Segwit2x intention involves the 2MB hard fork which is scheduled to occur in November.

However, weeks before the recent hard fork, a large portion of the user-activated soft fork (UASF) supporters, and Core developers have been vehemently opposing the second half of the NYA plan. Now that Bitcoin Cash exists, this has caused quite a few people to start envisioning three bitcoins; one that has Segwit only, one with both Segwit and the 2MB block increase, and the 8MB Bitcoin Cash.

On August 4 one individual wrote about his concerns about this outcome on the subreddit r/btc called, Core Devs: it is imperative that you endorse Segwit2x. If you dont, then we can end up with three Bitcoins. Please, have a little humility, avoid another contentious hard fork.

The person believes that if Core developers and many other others refuse to follow through with the second part of the plan, then there could be another chain split. Doubling the block size of the Bitcoin blockchain is NOT the end of the world, and it will come with many benefits as well, explains the threads author. One of the Core Bitcoin repository contributors, Luke-jr, reveals his opinion regarding the 2MB portion of the NYA plan.

Forget it Segwit2x is not going to happen If you want my support, get the proposal changed to something sane, explains Core developer Luke-jr. Then Luke-jr replied to the statement of how doubling the block size would not be the end of the world. Yes, it is, the developer adds.

Luke-jr is not the only bitcoin developer that wont agree to the next part of the Segwit2x plan. This includes Greg Maxwell, Wladimir van der laan, Jorge Timon, Eric Lombrozo, and many others.

After the birth of Bitcoin Cash, Jeff Garzik, one of the lead maintainers of the Segwit2x code, confirms that Segwit2x is still on schedule. When asked on Twitter whether the compromise was going forward because big blockers got their wish with Bitcoin Cash, Garzik responds saying;

Segwit2x and NYA have successfully met all goals so far, and continue as planned.

After August 1st the playing field is starting to get veryinteresting, and because the UASF and UAHF were planned in advance, many Bitcoiners had a feeling something was going to happen. Quite a few UASF supporters believe the UASF movement is what managed to push Segwit. However, these samesupporters seem to have also caused some blowback as well with the UAHF (Bitcoin Cash) plan following shortly after the movement started.

Now even though Segwit2x has a large majority of miner support and lots of businesses and infrastructure behind it, we could still see another split. Theres over three months left for the Bitcoin community to work this out, but some believe its looking dreary already.

What do you think about the upcoming plans for Segwit2x? Do you think its possible we could see three sets of bitcoins? Let us know in the comments below.

Bitcoin Price Surges Past $3,200 to Hit All-Time High - CoinDesk - CoinDesk

Two of the world's largest digital currency exchanges have changed their minds and decided to support the new asset "bitcoin cash", but customers will have to wait until January 2018 to gain access to their tokens.

"We've examined all of the relevant issues and have decided to work on adding support for bitcoin cash for Coinbase customers," David Farmer, director of communications at Coinbase, posted online on Thursday. An almost identically worded press release was posted by GDAX.

"We are planning to have support for bitcoin cash by January 1, 2018, assuming no additional risks emerge during that time."

Coinbase, which claims to have 9 million users, and its subsidiary the Global Digital Asset Exchange (GDAX) initially told customers they could not safely support the new crypto currency created on Tuesday on their exchanges, citing concerns about the asset's stability and security.

However, the exchanges decided to change their stance due to customer demand and trading volumes, among other reasons.

Charles Hayter, chief executive and founder of digital currency comparison website CryptoCompare, says there is also an economic reason for the shift in stance.

"Some exchanges are realising that they are missing out on trading fees and also seeing an exodus of clients to platforms that do support bitcoin cash," he told CNBC via email.

Some Coinbase and GDAX customers are unhappy with the exchanges' decision and took to Twitter to express their frustration. Others decided to withdraw their funds from the exchanges due to their initial stance.

"Bitcoin cash" was created on Tuesday after the underlying bitcoin technology known as the blockchain underwent a "fork", meaning it split to create a new digital currency. This happened because the community disagreed on how to increase the blockchain's capacity and reduce transaction delays.

Every bitcoin investor was entitled to the same number of "bitcoin cash" tokens, but not every exchange or bitcoin payment company is accepting the new coin, or allowing it to be traded.

'Bitcoin cash' prices fall by 57 percent, while some investors must wait until 2018 to receive their tokens - CNBC

A new version of bitcoin hit the market on Tuesday and, on its second day of trading, it has already tripled in price and its market cap is now third biggest of all digital currencies.

Known as Bitcoin Cash, the new currency arrived via a so-called " fork " in which a faction of people who run the software that controls bitcoin started a breakaway version.

The price of Bitcoin Cash hovered between $200 and $300 for most of Tuesday and then suddenly shot up. As this screenshot from CoinMarketCap shows (look to the right of the graph), Bitcoin Cash has also appreciated in relation to bitcoinone unit of the new currency is now worth about 30% of the original one:

Meanwhile, the price of the original bitcoin has, contrary to the fears of many bitcoin owners prior to the split, maintained its value. On Wednesday, bitcoin was trading around $2,700, which is not far from its all-time high of $3000.

As for Bitcoin Cash, it can be seen as a new asset class that achieved a valuation of $12 billion literally overnight (Update: as of mid-afternoon, the price had fallen to closer to $450 for a market cap closer to $8 billion.)

It's unclear if Bitcoin Cash will be able maintain its value since, like other digital currencies, its real world use is limited and its value derives primarily from what investors assign to it.

And part of Bitcoin Cash's surge in value may be tied to a liquidity issue arising from a decision by some exchanges to refuse to distribute the new currency to their customers.

The creation of the fork in bitcoin's blockchainthe software ledger that permanently records all transactionsby a minority of bitcoin operators followed a period of bitter infighting in the bitcoin community.

The details are esoteric (they center on the size and processing speed of the "blocks" on the blockchain), but the upshot is there are now two bitcoin blockchains, each with its own currency.

Get Data Sheet , Fortunes technology newsletter.

Upon the creation of the new chain, the breakaway faction chose to award Bitcoin Cash on a one-for-one ratio to every owner of bitcoin. So if a person owns five bitcoins, they are entitled to five units of Bitcoin Cash.

This scheme has been complicated, however, by the decision of the world's biggest bitcoin exchange, Coinbase, not to support Bitcoin Cash. For practical purposes, this means the millions of people who maintain a wallet on Coinbase did not receive the new "Cash" and, as of now, there is no way for them to do so.

Coinbase has clearly stated the company is not taking customers' Bitcoin Cash for themselves, but its decision to withhold the new currency has led one prominent legal scholar to suggest the company will be sued.

And, indeed, that now looks likely to transpire. An activist group, which claims Coinbase's decision is akin to a brokerage withholding new shares from its investors, warns it will commence a class action suit after August 15 if the company doesn't release the Bitcoin Cash.

Meanwhile, an attorney named Priyanka Ghosh-Murthy told Fortune she intends to file a complaintinvoking negligence, breach of fiduciary duty, and unjust enrichmentin Florida by the end of the week.

Coinbase, which set out its decision on Bitcoin Cash in a July 27 blog post, did not immediately respond to a request for comment.

Update : On Thursday afternoon, Coinbase reversed course and said it would support Bitcoin Cashbut only starting in January, 2018.

If you owned bitcoin prior to Aug. 1 and slept in a little that morning, you would have woken up to find your stash had doubledsort of.

Before Aug. 1, there was a single bitcoin currency simply called bitcoin, or BTC. Like most cryptocurrencies, bitcoin avoided having a central bank that verified transactions by maintaining a constantly verified ledger of transactions that was distributed across thousands of computers. This ledger is called the blockchain, and up until Aug. 1, there was only one of it. That day, at 8 a.m. Eastern, an alternative coin called Bitcoin Cash, or BCC, was born when the bitcoin blockchain split in two. Bitcoin Core, as the original currency is now called, and Bitcoin Cash have identical ledgers until Aug. 1. Now each currency maintains a separate ledger, and since cryptocurrencies are represented by their blockchains, that means bitcoin has effectively split in half, giving each user a bank account filled with both currencies.

The question of why bitcoin split is a deeply political one, as much about the philosophy of what bitcoin should be as it is about practical concerns of payment speed and per payment surcharges. As David Z. Morris described in Future Tense in June, the dispute centers on the maximum size allowed for any block in the blockchain. This is a technical point, but you can think of it as arguing over how many transactions are allowed on one page of the ledger. The original limit, imposed by pseudonymous creator Satoshi Nakamoto either as doctrine or temporary fillerdepending on whether you support BTC or BCCwas 1 MB of data. This low limit is leading to delays in the amount of time it takes a transaction to be verified, which is itself leading to higher surcharges for premium verification. (For a primer on how this all works, click here.)

If transaction time were the only issue, though, there wouldnt be a three-year-long flame war and a battling subreddits, one for each coin. There are two other issues. One is that the BTH folks think that allowing larger blocks hinders small players from mining bitcoins, centralizing power in the hands of large mining entities. Bitcoin was created as an alternative to centralized currencies, however, so greater centralization is a serious accusation. Point for BTC.

BTC has proposed a size increase of its own, one that comes with an even greater philosophical change. Segregated Witness, also known as SegWit2x, aims to fit more transactions on one page of the blockchain ledger by doubling the size of the page (that is, doubling the blocksize limit), and by reserving all space on the page for transactions. Right now, each page (each block) contains transaction details (Alice gave Bob 2 BTC), and signatures (I, Alice, agree to give Bob these 2 BTC). Instead of making the page much longer, SegWit2x wants to create more space on the page by erasing the signatures and reserving that space for transactions. Many believe this proposal changes the fundamentals of bitcoin more than BCC does, and in terms of structure of the chain, they are right. Thats why some supporters of BCC oppose the name alternative coin, they view what theyre doing as closer to Satoshis vision than BTC. Point for BCC.

However, the Highlander there can be only one approach is a false choice. To understand why, we need to look at the recent history of another cryptocurrency, Ethereum. Back in June 2016, $50 million were siphoned away from the Ethereum blockchain by some clever thieves. However, the thieves werent quite as clever as they thought. Because of the way they drained the money, they had to wait 28 days before they could withdraw it and, presumably, retire to some tropical locale. In that time, Ethereum made a hard choice, one that Gavin Wood, co-founder of Ethereum, called the single most important moment in cryptocurrency history since the birth of Bitcoin. Rather than let the thieves make away with the money, a large portion of Ethereum users forked the blockchain so that the transactions that stole the ETH never happened.

A lot of people were upset by this. It violated the spirit of the blockchain. The purists split off and started their own cryptocurrency called Ethereum Classic (ETC). A year later, both currencies are still used (though ETH is worth far more than ETC) and are fairly stable. In fact, their combined value is greater than the original value.

The same thing seems to be happening with bitcoin. According to Quartz, BCC is already the third most valuable cryptocurrency, behind BTC and ETH. And, just like the Ethereum split, the BTC-BCC market is worth more than the original market was. However, while there can be more than one currency, thats not to say there will be. It took six hours for the first BCC block to be mined, a process which usually takes about 10 minutes on BTC. That block was 1.9 MB, larger that BTC would allow, but the next block on BCC was only .04 MB, stoking fear that not enough miners had adopted BCC. Whether the achievement of BCCs debut as a new cryptocurrency is a Pyrrhic victory for the founders or a resounding success will hinge on the answer to that question.

Bitcoin Has Split Into Two Cryptocurrencies. What, Exactly, Does That Mean? - Slate Magazine (blog)

Coinbase, one of the worlds largest (if not the) largest cryptocurrency exchanges, has reversed its stance on Bitcoin Cash and said it will introduce support for the fork next year.

Coinbase was among numerous exchanges to opt out of trading Bitcoin Cash after it came into existence on August 1 on the grounds that it wasnt proven or safe. Beyond refusing to facilitate trading, Coinbase also said it wouldnt allow customers storing original Bitcoin on its platform to claim their Bitcoin Cash entitlement. Those who wanted it were told to remove their coins and go elsewhere to do that.

But now the company which was started by former Airbnb engineer Brian Armstrong (pictured above) and is reportedly raising funding at a $1 billion valuation has changed its stance slightly. It told customers via email that it will introduce support for Bitcoin Cash by January 1.

Once supported, customers will be able to withdraw Bitcoin Cash. Well make a determination at a later date about adding trading support, Coinbase said.

In other words, lets see what happens before we commit to trading

Thats almost certainly a response to anger from Coinbase customers, who threatened to move their coins elsewhere and, in some cases, take legal action over their Bitcoin Cash entitlement. (Tl;dr people like free stuff, especially people who are into crypto.)It is unclear exactly what impact this had on the Coinbase business, but signs arent great.One analytics firm estimated that its cold storage reserves dropped to half of their previous level following customer withdraws.

Yet, despite that, a number of Coinbase investors told Business Insider that they arent overly concerned about the pushback, while the overall future of Bitcoin Cash itself is unclear. Principally thats because the fork has the same mining difficulty as Bitcoin, but asmaller fraction of its hashrate.

Right now, Bitcoin Cash became the third largest cryptocurrency based on total coins in the market on day one, but its $7 billion market cap trails Bitcoin ($44 billion) and Ethereum ($21 billion) by some way. Its situation mayhave changed by January, too, while also Coinbase has tended to take a conservative approach to bringing new currencies on.

Right now it offers trading for Bitcoin, Ethereum and Litecoin the latter of which was only added this past May despite gaining significant attention in 2013. Indeed, Litecoins founderhad been director of engineering at Coinbase for nearly four years before leaving this summer that gives some insight into how stringent its policy is.

Note: Article corrected to note that Litecoin founder Charlie Lee is no longer with Coinbase.

Sobit was jointly developed by Japans leading reward site operator Ceres Inc and the Tokyo-based bitcoin and blockchain venture company Janom LLC.

Ceres has already partnered with other prominent bitcoin companies including Bitflyer, Bitbank, Coincheck, and Breadwallet on other cryptocurrency projects. Janom launched a bitcoin remittance service called Cointip in November 2016 and the company also partnered with Keepkey LLC to obtain exclusive distribution right of Keepkey products in Japan.Ceres Inc recently announced the launch of Sobit:

With Sobit, you can charge your prepaid SIM card using just bitcoin. You dont need any accounts, credit cards etc. Just a wallet with available bitcoin. Sobit supports prepaid SIM cards from over 600 operators in almost 140 countries.

Users first enter their phone numbers to use Sobit, even though the system should correctly detect the operator of each phone number most of the time, the company conveyed. Once the right operator is selected, the user can check the rates, choose the desired top-up amount, type in their email address and send bitcoin through the QR code provided or via their bitcoin wallets. The company states:

We will charge your phone as soon as your bitcoin transaction gets one confirmation, which may take up to 10 minutes (it depends mostly on your bitcoin wallet and fee settings).

Users will also get an email confirmation with their order details. While you should get your top-up immediately, for some countries or operators, there may be significant delays, even up to 24 hours, Sobit cautioned.

Currently, only payments equivalent to $100 maximum per day will be accepted due to technical reasons, the company added.

On Sobits website, 136 countries are listed. In the U.S., supported operators include Verizon, T-mobile, AT&T, H2O, and Net10. In the UK, they include Orange, T-mobile, Virgin Mobile and Vodafone. In China, they are China Mobile, China Telecom and China Unicom.
