Up fourfold, but bitcoin still a suspect; can save India $7 billion every year

Crypto-currency bitcoin still has few takers in India despite its stupendous rise elsewhere. But bitcoin wallet provider Zebpay is confident of rapid adoption in the country in the days ahead and says it can save India $5-7 billion in remittance fee alone every year.

The Singapore-headquartered firm started India’s first bitcoin exchange in 2012, and has offices in Mumbai and Ahmedabad.

India has been at least three years behind the world in embracing the bitcoin. Zebpay says its mobile app downloads have already crossed the 10 lakh mark and trading volumes are doubling every four months.

Wild swings in the non-fiat currency earlier this month did not help generate confidence among potential users.

The digital currency tumbled nearly 35 per cent between September 1 and September 15 in India, but bounced back 24 per cent to trade at Rs 2,79,262 per bitcoin on September 18 compared with Rs 2,25,121 on September 15.

Globally, it plunged some 27 per cent between September 7 and 15 in global markets.

The bitcoin has surged fourfold to trade at $4,208 on September 27, 2017 from $1,000 on January 2, 2017, hitting a peak of $4,950 on September 1. Some argue that many potential investors may have lost a chance to tap an emerging theme for wealth creation thanks mainly to lack of regulatory clarity.

Bitcoin is a revolutionary technology and can help Prime Minister Narendra Modi’s dreams of financial inclusion and Digital India, says Sandeep Goenka, Co-founder, Zebpay.

On Thursday, Indian markets regulator Sebi (Securities and Exchange Board of India) said it was planning a framework to regulate the bitcoin market in India.

At a September 19 meeting, its first, the Sebi panel on financial and regulatory technologies (CFRT), concluded that it might be crucial to regulate bitcoin transactions to ensure that India’s public issue norms are not breached, Mint reported.

Chinese regulators clamped down on crypto-currencies earlier this month, which forced BTCChina, one of the biggest bitcoin exchanges in the world, to announce on September 14 that it would shut down trading activities on its platform from September 30.

Wall Street bankers have been in two camps with their views on the bitcoin. JPMorgan Chase CEO Jamie Dimon recently called the bitcoin a ‘fraud’ and said governments could eventually crack down on crypto-currencies. Morgan Stanley CEO James Gorman earlier this week differed with Dimon and called the bitcoin “more than just a fad.”

India’s central bank says it is not comfortable with ‘non-fiat’ cryptocurrencies, Executive Director Sudarshan Sen said this past fortnight.

But going by Zebpay’s growth projections, RBI might soon have to sit up and take a serious note of the bitcoin.

The trend will continue to rise. In last eight years, bitcoin has witnessed hurdles in the initial phases in every country, but has still grown, says Goenka.

The focus right now is on the potential misuse of the technology. Once people realise the benefit of the technology, they start adopting it. The same has happened in the US, the UK and Japan.

India is going through the same phase of understanding the technology, says Goenka.

This technology has the potential to make India a global fintech hub. It can save billions of dollars in remittance fee that overseas Indians pay to US firms for money transfer back home. “For this privilege, we pay US firms $5-7 billion dollars a year,” Goenka said.

Globally, there has often been talk of a possible bubble in bitcoins, which has grown exponentially over the years.

Goenka is not convinced. The rise in bitcoin prices is no bubble. It is a fundamental technology and would change society sooner than later, he insists.

People who think it’s a bubble are fundamentally averse to the idea of technology or they don’t understand the potential of this technology, says Goenka.

SHANGHAI (Reuters) - Weeks after Beijing banned fundraising through token launches and ordered some bitcoin exchanges to shut, casting a chill over the cryptocurrency industry, traders say that the market is far from dead.

While several exchanges have announced that they will close by the end of this month, traders have now moved to buy and sell bitcoin directly with each other on peer-to-peer marketplaces and messenger apps. Industry insiders say some overseas-based initial coin offerings (ICOs) are still being marketed.

Although the crackdown has dissuaded large swathes of less-experienced investors from participating in the trade, market participants point to the limits Chinese regulators ultimately face in controlling the industry, where many users are anonymous and difficult to track.

In the short-run, the crackdown has also created an arbitrage opportunity for investors, with the price of bitcoin in China now trading at a discount to overseas exchanges.

“They can’t set rules to stop me from investing in what I want to invest in. They say you are protecting me, but as long as I think this is good, they have no way to intervene,” said a Chinese bitcoin investor named Victor, who declined to give his full name citing current sensitivities.

“I can do over-the-counter trades or I’ll go offshore...My wallet is my wallet. I’ve never registered my identification card.”

The Chinese government on Sept. 4 ordered ICOs to cease and soon after ordered some cryptocurrency exchanges to shut. Over 15 exchanges, including the three largest players OkCoin, Huobi and BTCChina, have since announced that they will close their mainland businesses by the end of September.

While the clampdown caused the bitcoin price in China to tumble as much as 8 percent on the day of the announcement, it has since recovered to 24,101 yuan ($3,615.67) on Chinese exchange Huobi. On U.S. exchange Bitstamp, it BTC=BTSP currently trades at $4,205.

Trading has spiked generally on peer-to-peer marketplaces, according to data website Coindance. On OTC platform LocalBitcoins, China trading volumes more than doubled in the week starting Sept. 16 from the previous week to 74 million yuan. It hit an all-time-high in the week starting Sept. 23, reaching 115 million yuan in trades.

Volumes on Paxful, another smaller marketplace, also jumped to 1.7 million in the week beginning Sept. 23, up from 351,102 in the previous week, Coindance data showed.

Michael Foster, co-founder of localethereum.com, an over-the-counter marketplace for ethereum trading, said mainland China users accounted for a fifth of its 5,000 signups since it opened for registrations on Tuesday.

“The fact that bitcoin is still being traded is an indication that China isn’t looking to eliminate them, but reposition things in a way to have better control over them,” said Marshall Swatt, the founder of New York-based Coinsetter, a bitcoin exchange acquired by larger peer San Francisco-based Kraken in 2016.

Other Chinese cryptocurrency players said traders were also moving away from using Tencent’s WeChat app, to encrypted messenger app Telegram to avoid regulatory scrutiny.

Some said they were still seeing overseas-based ICOs being marketed in China. The Sept. 4 shutdown of ICOs stipulated that Chinese citizens were not allowed to invest in ICOs. Overseas ICOs have been returning money on a voluntary basis.

“The trend of digital currency transactions moving offshore is inevitable,” Zeng Danhua, the co-author of a bitcoin investment guide, told a television program filmed by Chinese financial news outlet Yicai on Wednesday.

“The regulators may have needed to shut the platforms to guard against financial risks, and there may be a bitcoin bubble, but its investment value persists.”

Ryan Charles recently switched his business, the social platform Yours Inc., from using bitcoin -- simply because he couldn’t afford it.

Fees for sending money over the distributed-ledger network have risen nearly 19-fold, from 13 cents per average transaction in the second quarter of 2016 to $2.40 in the same quarter of this year, according to researcher CoinDesk. While they’ve moderated somewhat since, the fees still undermine the San Francisco-based company’s business model, which is built around writers receiving small payments from readers of their posts.

"Bitcoin is now in a situation where the fees are very high and are likely to continue to increase, so it’s not even competitive with PayPal or Western Union in most cases," Charles said in a phone interview.

When bitcoin debuted in 2009 it was hailed as a technology that would revolutionize the world of finance by making micro-payments practicable, and international money transfers cheaper than Western Union Co. In some cases, particularly in low-value transactions, fees to run payments over the blockchain technology based network can actually be higher.

The fees go to so-called miners, whose computers run the software that makes the network tick. Miners didn’t suddenly raise prices. The bitcoin blockchain is a supply-and-demand-driven system. When there’s lots of demand, users have to pay higher prices for transactions to post fast. They can pay lower fees, but then the payments will get a low priority, and postings could take days. Most consumers don’t even know about the low-cost option: They simply pay fees imposed by what are known as wallet companies that facilitate transactions. And fees have been spiking often.

That’s making bitcoin impracticable for many people. Nearly 60 percent of the world’s bitcoin owners hold less than $4 at current prices, according to BitInfoCharts. At the recent average of $2.46 per transaction on the bitcoin blockchain, the fees would swallow most of the funds. On Aug. 22, the average transaction fee was $8.90, according to Lucas Nuzzi, senior analyst at Digital Asset Research.

For many companies hoping to do commerce via bitcoin, the fees are prohibitive, especially in emerging economies like India and Vietnam, where consumers often earn a few dollars a day. Even U.S. residents can feel the burn. It can cost as much as $15 to send $25 from the U.S. to a bank account in the U.K. via bitcoin, or three times as much as using Western Union, Nuzzi said.

"It’s very cumbersome and complicated,” said Khalid Fellahi, head of Western Union Digital in San Francisco. “We haven’t seen that today being an alternative to what we do.”

To send the $25 from the U.S., Nuzzi used a credit card to buy an equivalent amount of bitcoin on exchange Coinbase Inc., which charged a 3.99-percent fee this month. Then he paid a bitcoin network fee of $1.34 to send the payment to the U.K. While converting bitcoin to pounds was free on the exchange Coinfloor, Nuzzi had to pay $13.56 to place the money in a U.K. bank account. He ended up paying $15.90 to get the payment through.

Granted, some users don’t convert to a fiat currency, and transact in bitcoin directly. But even those users would pay fees to miners.

"Bitcoin cannot be used properly for commerce when a transaction costs more than $2," said Shaun Chong, lead developer of mining community Bitcoin.com Pool, which makes between 10 percent and 30 percent more in revenue now that the fees are higher.

"If the fees were lower, the bitcoin price would be even higher because bitcoin would be more usable," Chong said, adding that in its current state, the network is "broken."

There are several reasons why network fees are so high. Many startups have been requiring investors to pay in bitcoin for Initial Coin Offerings. Since those were often only open for a limited period of time, investors sped up money transfers to avoid missing out, pushing costs higher, said Nuzzi.

What’s more, as bitcoin’s profile rose, the network often got overloaded. With demand high, and supply short, transaction prices went up.

Some of the fees may decline in time. Developers are working on different ways of expanding the network’s capacity, with one major fix implemented in late August, and another due in a few months.

But bitcoin developers remain split over how to improve capacity. Already, some of them decided to create and run a separate bitcoin-like digital ledger called bitcoin cash earlier this year. And another split off could be coming in November. Even if the most promising solution, called Lightning Network, is implemented, fees could remain high as demand increases, said Charles. That’s why he switched to bitcoin cash, which charges lower fees.

"We see bitcoin losing market share in comparison to other currencies if more events like that spike network fees," Nuzzi said. There are around 1,000 digital currencies and nearly all of them charge lower transaction fees than bitcoin right now. So some entrepreneurs and users are moving to litecoin, bitcoin cash or ethereum to find better prices.

"Bitcoin has a lot of value in terms of moving large amounts of value using digital currency," said Jeremy Allaire, chief executive officer of cryptocurrency exchange operator Circle Internet Financial Ltd. "The fees don’t matter when you are dealing with larger transactions. If you are using it for a $25 transaction –- then yeah, the fees would be too much."

As transactions get more expensive, perceptions of what bitcoin is are changing, too. Because there will only ever be 21 million bitcoin issued, it’s considered to be a scarce resource that investors can park money in, hoping for appreciation. Already, bitcoin’s price has nearly quadrupled this year, despite pressure from Chinese regulators.

"It’s forced bitcoin into moving away from being a cheap payment system to being a store of value like digital gold," said Anthony Di Iorio, founder of digital wallet provider Jaxx.

Japanese banks are thinking of making their own cryptocurrency called the J-Coin



Japanese banks are looking to launch their own digital currency called the J-Coin to wean consumers off cash.

Mizuho Financial Group is one of the institutions spearheading the move.

"The project is in the early stages, and we have just held study meetings with other institutions," a spokesperson for the bank told CNBC via email Wednesday.

The Financial Times reported Tuesday that a consortium of banks including Japan Post Bank was involved and that the J-Coin would launch in time for the Tokyo Olympics in 2020. The Mizuho spokesperson declined to comment on the involvement of other banks or the timeline.

However, the spokesperson told CNBC that there hasn't been any approval from regulators yet and provided more details on the plans for the digital currency.

"This will be pegged with Japanese Yen, and hopefully used to make payments and transfers through a mobile phone app," the bank said.

Mizuho has been exploring the digital currency space for the past few months. It has had a particular interest in blockchain technology that underpins the cryptocurrencies currently on the market. Blockchain is a distributed ledger system that promises to revolutionize many processes at large financial institutions, such as money transfers and trade finance, for example.

Earlier this year, Mizuho completed a trade finance transaction via a blockchain. This involved sending information from Japan to Australia with key documents such as the letter of credit, all being completed on a digital platform backed by blockchain technology.

Japan's government has also been open to the idea of digital currencies. Earlier this year, bitcoin was legalized as a legal payment method in Japan and large retailers began accepting the cryptocurrency. But cash is still heavily used in Japan. The J-Coin could be a way to wean Japanese society off of cash.

As China cracks down, Japan is fast becoming the powerhouse of the bitcoin market


A decision by Japanese authorities is helping the country cement its place as a driving force for bitcoin, at a time when China is turning its back on virtual currencies.

On Friday, Japan's Financial Services Agency (FSA) officially recognized 11 companies as registered cryptocurrency exchange operators. The registration places several requirements on the companies, such as building a strong computer system and checking the identity of users to prevent money laundering. These regulations are intended to protect investors from fraud and other abuse, while supporting financial technology innovation.

One of the registered companies is bitFlyer, which has more than 800,000 users, according to the firm. The company's CEO, Yuzo Kano, said the new rules cements Japan's position as the epicenter for bitcoin.

"Japan has been exploding with demand for both bitcoin trading as well as virtual currency services," Kano said in a press release Friday.

"The FSA's approval for bitFlyer to operate as a Registered Virtual Currency Exchange, and the agency's openness and forward thinking regulation could not come at a better time for the blockchain space."

Blockchain is a digital leger that is dispersed across networks. It is used in the cryptocurrency space to securely record every transaction between users.



This is the latest decision in Japan to show support for digital currency. In April, it passed a law recognizing bitcoin as legal tender, with several retailers backing the law; this week it was reported that Japanese banks are considering setting up their own digital currency called the J-Coin.

Japan's stance is in stark contrast to China, where regulators have cracked down on the market. At the beginning of September, regulators banned initial coin offerings (ICOs), where companies raise funds by selling a new digital currency. Several bitcoin exchanges then announced they would end trading by the end of the month.

The news from China initially caused bitcoin prices to fall sharply, from a record high above $5,000 per bitcoin at the beginning of September to a low of $2,951 by mid-September. The price has since recovered to around $4,208.63, according to CoinDesk data.

Part of the reason for the sharp fall is China used to be the main driver of the bitcoin market. Between 2014 and January 2017, the Chinese market made up around 90 percent of global bitcoin trading volume.

But now trading volume is more distributed around the globe than ever before, with trading in U.S. dollars and Japanese yen outsizing volume in Chinese yuan, according to data from CoinDesk.

Not only that, but the market is now moving on from China. Chinese investors are now trading bitcoin directly to one another on peer-to-peer platforms and apps rather than the exchanges, Reuters reported Friday.

In fact, bitcoin priced in China's currency is now trading at a discount to bitcoin in other currencies, which has created an arbitrage opportunity for some investors. For instance, bitcoin's price in Chinese yuan is 26,499 ($3,989.13), compared to bitcoin's U.S. dollar price of $4,208.63.

"Japan and the U.S. have proven China is unnecessary for bitcoin to thrive," Charles Hayter, chief executive and founder of digital currency comparison website Crypto Compare, told CNBC in an email on Friday.

"As various nation states pin their colours to the mast, a whole panoply of differing attitudes will be seen. This industry is mobile and it will come to roost in the most favourable jurisdictions."

thank you

For years, cybercriminals have been extorting victims by locking their computers with malware. The hackers promise to give the victim their files back as long as they fork over the cryptocurrency—typically Bitcoin—within the stipulated time limit. Now, someone has added a new, perverse twist to this tried and tested scheme: demanding naked photographs instead of Bitcoin.

Researchers at MalwareHunterTeam, a research group focused on ransomware, spotted the software, called nRansomware on Thursday. The group posted a screenshot of the message that's displayed when a victim gets infected:

"Your computer has been locked," reads the message, which then asks the victim to email the hackers. "After we reply, you must send at least 10 nude pictures of you. After that we will have to verify that the nudes belong to you."

The message is displayed on top of an haphazard background made of several images of the fictional children's character Thomas the Tank Engine and a smiley face with the writing "FUCK YOU!!!" in bold. It's not clear how many people have been hit with this ransomware, or how serious the hackers behind it really are.

To some extent, the malware does appear to be legitimate. The file, nRansom.exe, is classified as malicious by several antivirus engines, including VirusTotal and Hybrid Analysis, which are both public malware repositories. Other users on Twitter also reported spotting more samples of this particular ransomware.

Malware can end up on these repositories if someone manually submits an entry and details what and does and how, or if malware is submitted and is then automatically analyzed. Motherboard attempted to infect a virtual machine with the malware but was unable to do so.

This could very well be a prank, given that it doesn't actually encrypt files, according to MalwareHunterTeam and another researcher who looked at the malware.

"It is a screenlocker, so files aren't encrypted," MalwareHunterTeam told Motherboard in a Twitter direct message. "We have no information about anyone getting infected with this."

The malware also appears to play looped music—from a file called your-mom-gay.mp3 that is actually the Curb Your Enthusiasm theme song—in the background, according to the MalwareHunterTeam.

We contacted the hackers via the email address included in their ransom message. They didn't immediately respond to our questions.

In any case, while this ransomware is clearly gross, sadly, it's not unexpected. Hackers have for years used malware to spy on women and steal their nudes or access their webcams.

the pump is being prepared with the news that Amazon will accept bitcoin

If they said mining is illegal they could not assemble and sell mining gear for the rest of the world

Will this only be for USA or worldwide?

I doubt price will ever reach $1800, unless because of a mr120 event.
So $7000 or a tie, if price never rises to $7000 again

They are preparing the next bitcoin dump with the amazon news, after the october hard ford

No it doesn't exist

But which wallets are the ETH ICO's using?

Don't know anything.

But I hope the name isn't mimicking Monero
