Bitcoin Gold Developer Under Scrutiny For Allegedly Hiding Mining Code

The bitcoin gold development team is under fire once again as the currency’s mining community has discovered a hard-coded hidden fee protocol found within one of the bitcoin gold developer’s mining pool code. Miners say that BTG core developer, Martin Kuvandzhiev (StarbugBG), added a hidden 0.5 percent fee into the pool code that pays the fees directly to his wallet.

Mining Community Lashes Out at Bitcoin Gold Developer Martin Kuvandzhiev

Bitcoin Gold Developer Under Scrutiny For Allegedly Hiding Mining CodeAs we reported last week the bitcoin gold(BTG) mainnet went live, and mining is now open to the public. When the project first launched it was reported that the mining pool Suprnova had an issue with a chain split situation. The mining community reveals that Suprnova and other BTG pools have stripped the hidden fee protocol from their mining software. According to rumors across forums the creator of BTG, Jack Liao, allegedly kept the pre-mine of 8,000 blocks for himself and speculators believe it provoked Kuvandzhiev to add the code which transfers a hidden fee to his Bulgarian mining pool.

“This explains why so many blocks found didn’t show up as paid to the finder, also why Suprnova’s chain was out of sync, perhaps Suprnova found this code removed it, and that pissed off dev-team,” explains a user.

A Fee for Contributing a BTG Open Source Mining Pool

Additionally, a complaint was sent to the team’s Github repository called issue #180“Beware of hidden fee hard-coded into z-nomp fork advertised by the devs.”

“Looks like ‘StarbugBG’ (Martin Kuvandzhiev) snuck a little easter egg in the form of a hidden 0.5% fee directly paid to his wallet via coinbase tx into the pool code he suggested everyone use,” details the Github issues creator.

However, Kuvandzhiev explains that the open source code wasn’t hidden and other pools are closed source. “Which is better?” asks Kuvandzhiev “Only one working pool which is closed source or an open source pool code that everyone can edit with 0.5% for the dev that has made this possible?”

0.5% for a regular miner is less than a $1 a month. Don’t act like it is too much. The other software has 1 – 2% fees and are closed source, you cannot remove it.

The mining pool issue has been known by developers and miners for two days but the news has just reached the public. Many unhappy developers and miners on Github express their opinions about the hidden fee setting.

Following the Controversial News, the Developer’s BTG Pool Closes Operations and Bitcoin Gold Markets Lose Significant Value

As soon as the news hit social media, forums and the team’s Slack channel the BTG mining community was in an uproar. Further, the currency’s markets have dropped in value significantly, as one BTG was $250 yesterday, and has since dropped to $150after the mining pool fee scandal was revealed. Alongside this, the mining pool allegedly run by Kuvandzhiev has closed its operations.

“Please note, is shutting down — Please relocate your miners to alternate pools at your earliest convenience,” notes the pool’s website. has reached out for a response from the bitcoin gold team and its lead developer “h4x3rotab.” “I’d like to help — Though maybe I don’t have enough time to answer all the questions in details,” explains the developer to via Slack. Since then the BTG team has yet to respond to our question concerning the mining pool incident created by the programmer Martin Kuvandzhiev.

Bitcoin surges in Zimbabwe as military seizes power

Bitcoin climbed as much as 10% on Zimbabwe’s Golix exchange on Wednesday after the country’s armed forces seized power.

The price of the cryptocurrency in the Southern African nation jumped as high as $13,499, almost double the rate at which it trades in international markets, according to prices cited on Golix’s website.

Demand for Bitcoin in Zimbabwe has surged amid a shortage of hard currency. Golix processed more than $1 million of transactions in the past 30 days, compared with turnover of $100,000 for the whole of 2016, according to data on the exchange’s website. Zimbabwe doesn’t have its own currency, with the government adopting the U.S. dollar and South African rand, among others, as legal tender in 2009 after hyperinflation rendered the local dollar worthless.

Golix, an unregulated platform that also trades other cryptocurrencies, has been in operation since 2014. Prices for Bitcoin are set by supply and demand, according to Taurai Chinyamakobvu, co-owner of the exchange. Sellers are paid in U.S. dollars deposited electronically, which can only be converted at a steep discount on the black market.

Zimbabwe’s army moved into the capital, Harare, on Tuesday after a week of confrontation with President Robert Mugabe’s government and said the action was needed to stave off violent conflict in the southern African nation that he has ruled since 1980.

Deep Crisis

The events unfolded as Zimbabwe is in deep crisis. The economy has halved in size since 2000, an estimated 95% of the workforce is jobless and as many as 3 million Zimbabweans have gone into exile.

While most major currencies are legal tender in Zimbabwe, cash-strapped importers and retailers buy dollars — or any currency easily converted to dollars — at premium prices by paying the seller electronically. A dollar buys about 8 South African rand, compared with the market exchange rate of 14.36 on Wednesday. Zimbabwe’s unpopular “bond notes” — promissory notes issued by the central bank and officially pegged to the dollar, are worth as little as 50 U.S. cents on the black market.

Everything You Need to Know About Bitcoin Black Friday

Black Friday, the internet’s annual day for rampant consumer excess, is looming. On November 24, an online spending spree the likes of which hasn’t been seen since the last one, and which won’t been seen till the next, shall commence. As Black Friday’s profile has risen in recent years, so has that of its sister event, Bitcoin Black Friday. But with many cryptocurrency owners choosing to hodl rather than spend, will this year’s BFF be a damp squib?

It’s Friday, Friday

Everything You Need to Know About Bitcoin Black Friday
Black Friday is on its way.

On Thursday November 23, Americans celebrate family and food by gathering their nearest and dearest and piling their plates high. The following day, the U.S. – and increasingly the rest of the world – fire up smartphones, tablets, and laptops, and load up on Black Friday bargains. Traditionally its been the credit card that’s borne the brunt of the strain, but for the past few years bitcoin has also been an option.

Bitcoin Black Friday was launched by crypto enthusiast Jon Holmquist in 2012, initially as a means of raising awareness of bitcoin. By his own admission, the cryptocurrency has been doing just fine in the awareness stakes of late; most people with the capacity to shop online have at least heard of bitcoin. For owners of the cryptocurrency, however, many of whom have seen their portfolio double, triple, or even 10x in value this year, parting with those precious coins – even for an event as monumental as Bitcoin Black Friday – is a big ask.

Spend and enjoy instant gratification or hodl in the hopes of deferred gratification as bitcoin rises further? It’s a dilemma.

Bitcoin Black Friday Welcomes its Crypto Brethren

For this year, BFF’s founder has welcomed all cryptocurrencies into the fold, writing “While the title of the event is still Bitcoin Black Friday, I think other digital currency communities should be able to participate.” Jon Holmquist told

The goal for this year is simply to provide a fun event for the Bitcoin community to participate in and support merchants who accept digital currencies. One extremely important change this year is that BBF, irregardless of the name, is now currency agnostic. If a merchant only accepts Bitcoin Cash, they can be listed.

So for those comfortable with the idea of splurging some satoshis on discounted gear, what sort of bitcoin bargains are there to be had?

Bitcoin’s Encryption Not Flawless?

Apparently quantum scientists have predicted that by 2027 there will be a quantum attack method that can hack any Bitcoin blockchain. I am not a quantum hacker myself so I can’t say if it’s possible or not, but I have read several articles on quantum computing. Whenever there is a new form of computing or some technological upgrade, you will have people attempting to hack / break this tech. Obviously Bitcoin chains are the freaking honeypot of a hacker’s wet dream. It’s not regulated, it’s a tough challenge, and you can read more below

Key protocols securing technology under-girding bitcoin are “susceptible to attack by the development of a sufficiently large quantum

computer,” researchers mostly from Singapore claim in a recently-released paper, Quantum attacks on Bitcoin, and how to protect against them (Quantum), made available through the Cornell University Library.

Why Aren’t There More Women in Bitcoin?

Take a look around the crypto community, both in meatspace and online, and it would be fair to say that the majority of participants are male. This is borne out in a recent survey of 2,000 Americans which shed light on the makeup of the bitcoin space, highlighting a stark gender divide. In fact Google Analytics data estimates less than 4% of bitcoin users to be female. The question is, why?

Welcome to the Boys’ Club

As reported earlier this week:

Twice as many men own or have owned bitcoin and are almost three times as likely as women to buy bitcoin in the next five years. Men also have a more positive view of bitcoin (17% versus 7%).

Why So Few Women in Bitcoin?

Tech industries are inherently male-dominated for reasons that include boys being introduced to gadgets at a younger age, leading to just 16% of computer science undergraduates being female. Despite initiatives designed to encourage more girls to code, the number of female computer science undergraduates in the UK has actually dropped in the last 10 years. Attributing other reasons to the absence of women in tech is highly contentious, as fired Google engineer James Damore discovered to his peril this year.

Boys and Bitcoin

Why Aren’t There More Women In Bitcoin?In its earliest days, bitcoin was a wild west that evoked memories of the dawn of the internet – another piece of tech whose earliest innovators and adopters were predominantly male. A degree of technical knowledge was required to fully utilize the web back then, and the same holds true of bitcoin even today. While the UX of bitcoin has since improved thanks to development at the application layer, cautionary tales of lost private keys, coins sent to wrong addresses, and phishing attempts are still abound. And those are the sort of mishaps that can befall even experienced operators.

For newcomers, there’s a lot to learn, and that’s not including the dogma surrounding bitcoin and competing claims on which chain is “true”. If bitcoin’s earliest adopters are drawn from industries which are historically male-dominated, it follows that later adopters will be less tech-savvy. Newcomers of both sexes, then, find themselves with a mountain of knowledge to climb.

Why Does Bitcoin Need More Women?

Why Aren’t There More Women In Bitcoin?It shouldn’t need stating that the more inclusive bitcoin is, the better. The cryptocurrency space doesn’t need diversity quotas, but if it is to attain mainstream adoption, it needs to attract support from all demographics. Bitcoin can hardly be labeled a global payment and wealth storage system if it excludes half of the population. While no one is stopping more women from getting involved with bitcoin, little is being done to encourage them either.

Credit must go to the likes of Rhian Lewis and Paige Freeman for organizing Women in Bitcoin events in London and San Francisco. These exceptions, unfortunately, only reiterate that bitcoin is largely a boys’ club.

Changing the status quo surely calls for action in the following areas:

Behavior. If Silicon Valley’s culture is overly macho, how to describe bitcoin with its brash, combative, and opinionated personalities? To misquote Hunter S Thompson:

Bitcoin is a cruel and shallow money trench, a long plastic hallway where thieves and pimps run free, and good men die like dogs. There’s also a negative side.

The cryptocurrency community is awesome, but it’s also intimidating and filled with one-upmanship and braggadocio. Why would anyone want to join such a rabble?

Why Aren’t There More Women In Bitcoin?
Can’t we just all get along?

Issues such as off-chain scaling and Merkle roots might keep bitcoin’s most brilliant minds up at night, but it’s interface design, aesthetics, user-friendliness, and on-ramping that will open up bitcoin to the masses.

More can be done to reach out to women and raise awareness of bitcoin and how it can benefit them. This is something that everyone in the crypto community could do better. There are ways to educate people about bitcoin without succumbing to accusations of ‘mansplaining’.

Women Don’t Want Pink

Women don’t want things to be pink and fluffy (despite what the developers of Womencoin seem to think), but they do want products that appeal to their interests. There are dedicated insurance websites, retail stores, casinos, and social media apps for women. When bitcoin starts catering to the needs of women, providing products that add value to their lives, progress will be made. Gimmicky coins and female-focused tokens do little to help.

If egalitarian reasons don’t spur developers into catering for women, financial incentives certainly will. There’s a vast number of moms, sisters, girlfriends, and colleagues out there with high disposable income and a love for all things internet. This presents a huge business opportunity for whoever can figure out a way to get these women into bitcoin and to get bitcoin into their everyday lives.

Bitcoin is amazing. It removes monetary control from governments, enhances privacy, and gives individuals financial freedom. And that’s something that every man and woman on this planet deserves to experience.

Bitcoin Academy ( Lesson 3 ) – Bitcoin

Legal status, tax and regulation

Because of bitcoin’s decentralized nature, restrictions or bans on it are impossible to enforce, although its use can be criminalized.[152]The legal status of bitcoin varies substantially from country to country and is still undefined or changing in many of them. While some countries have explicitly allowed its use and trade, others have banned or restricted it. Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems.[153]

Criminal activity

The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and the media.[154]The FBI prepared an intelligence assessment,[155] the SEC has issued a pointed warning about investment schemes using virtual currencies,[154] and the US Senate held a hearing on virtual currencies in November 2013.[72]

Several news outlets have asserted that the popularity of bitcoins hinges on the ability to use them to purchase illegal goods.[91][156] In 2014, researchers at the University of Kentucky found “robust evidence that computer programming enthusiasts and illegal activity drive interest in bitcoin, and find limited or no support for political and investment motives.”[157]


Bitcoin has been criticized for the vast amounts of electricity consumed by mining. It has been estimated that annual consumption (as of 2017) was 23 terawatt hours, approximately the same as the country of Ecuador.[158]

The transaction times vary from several seconds to several hours depending on offered transaction fee and other technical reasons.[159][better source needed]

In academia


In September 2015, the establishment of the peer-reviewed academic journal Ledger (ISSN 2379-5980) was announced. It will cover studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh.[160][161] The journal encourages authors to digitally sign a file hash of submitted papers, which will then be timestamped into the bitcoin blockchain. Authors are also asked to include a personal bitcoin address in the first page of their papers.[162][163]


In the fall of 2014, undergraduate students at the Massachusetts Institute of Technology (MIT) each received bitcoins worth $100 “to better understand this emerging technology”. The bitcoins were not provided by MIT but rather the MIT Bitcoin Club, a student-run club.[164][165]

In 2016, Stanford University launched a lab course on building bitcoin-enabled applications.[166]

In art, entertainment, and media


The documentary film, The Rise and Rise of Bitcoin (late 2014), features interviews with people who use bitcoin, such as a computer programmer and a drug dealer.[167]


Several lighthearted songs celebrating bitcoin have been released.[168]
