It would be great if the team at Steemit use synergy as a strategy to growth this platform.

The Synereo team will launch the Qrator browser in June of this year, Qrator will allow users to share quality content from themselves or others and get paid for it.

This can be a huge opportunity for Steemit to grow and don't let Synereo just get all the cake! since both platforms are in the attention economy business, both can benefit and grow, also Steemit will help it's users and investors to get more value from this opportunity.

Chasing the Next Bitcoin, Investors Shell Out $700 Million for Coins With ‘No Purpose’

Startup block.one is benefiting from a boom in initial coin offerings as bitcoin’s price surges to dizzying heights

One of the hottest cryptocurrency investments of 2017 comes from a software startup that doesn’t plan to sell any software and describes what it is selling—something called a digital token—as having “no purpose.”

The company, block.one, has raised about $700 million and counting. That is larger than all but 10 of the 195 U.S. initial public offerings this year.

The sale of the token, called EOS, has benefited from a boom in initial coin offerings, a fast-growing fundraising method tied to investors’ desire to get in on cryptocurrency mania. Those offerings took off this year as bitcoin’s price surged 19-fold.

Overall, 165 firms have raised more than $4 billion in 2017 through coin offerings, which resemble crowdfunding campaigns more than traditional fundraising tactics like selling equity or attracting venture capital.

The block.one offering is by far the largest to date—its market value is now about $4.5 billion—and it illustrates both the promise and concerns of this opaque marketplace.

It also shows that investors are looking to get in on anything related to virtual currencies.

Started late last year and registered in the Cayman Islands, block.one essentially is a software company, writing code for its main project: a bitcoin-like operating platform, akin to Google’s Android, for hosting any variety of applications. The company has about 50 employees but no central office, according to a person familiar with the matter. Developers work on their code via an open-source development website.

EOS is the idea of Brendan Blumer, a relatively unknown 31-year-old internet entrepreneur in Hong Kong, and Dan Larimer, a gifted programmer who has jumped around after brief stints at various startups.  Brock Pierce, a former child actor and prominent bitcoin investor, is a minority partner and adviser who talks often about the company at conferences.

Block.one’s website doesn’t say much about its key employees. It has pictures of 16 “team” members, but no biographical information or titles. Its 14-page white paper posted on the site describes new software that promises to handle millions of transactions per second. It also links to a collection of videos and blog posts describing how the company could use bitcoin’s decentralized “blockchain” technology for various purposes. “What would a blockchain Constitution look like?” Mr. Larimer asked in one post.

On a different part of the site, investors in many countries, excluding the U.S. and China, can click a link that takes them to a daily auction. Each day, block.one sells two million new tokens to investors who sign up in the auction to buy.

By contrast, fashion startup Stitch Fix Inc .  sold shares to the public last month after six years of methodical growth. Its 159-page offering document drafted by seven major investment banks featured detailed backgrounds of top managers, along with a letter from the company’s founder and CEO, Katrina Lake. The company with 5,800 employees and $977 million in annual revenue raised only about $120 million, less than a quarter of what block.one did.

Unlike some coin offerings, which offer virtually no details, the EOS software code is posted publicly and the firm last week released an early version of it. Block.one is planning a full rollout next June, which Mr. Pierce recently predicted would be “like Windows launching, but much bigger.”

The twist, though, is that unlike Microsoft Corp., block.one plans only to write the initial code for EOS and then release it publicly. It won’t build or develop the platform itself, leaving that task for unrelated third parties. Whether any groups would do that is unclear.

Because of that, the EOS tokens have no actual relationship to the software. A purchase agreement that investors must sign states the tokens “do not have any rights, uses, purpose, attributes, functionalities or features.”

Even though the language of the agreement suggests the tokens have no intrinsic value, investors have been eagerly bidding for them. Mosala Sehloho, a 32-year-old media producer in Johannesburg, said he understands the EOS tokens made no contractual promises, but he thinks the $10,000 worth he bought will rise in value. “I’d buy more” if the price dropped enough, he said in November. “This will be the technology that will be the best of its kind.”

Matthew Roszak, one of block.one’s early investors, said EOS holders shouldn’t worry too much about the warnings the company has given about the tokens. “I don’t think it’s fair reading into that language too tightly,” he said. Given the “regulatory environment is as clear as mud,” he said block.one needed to write something to provide the broadest protection possible.

Other investors, including Rik Willard, founder of consulting firm Agentic Group, have avoided EOS tokens because the technology is unproven and the token may not benefit even if the company does well. The demand for a token like EOS “just shows the frenzy,” Mr. Willard said.

Block.one’s EOS deal is now about three times as large as the next biggest coin offering. It plans to keep raising money until next June and is on pace to raise “well north of” $1 billion, according to Mr. Pierce’s remarks in a panel discussion in October.

Mr. Blumer has said that block.one will use that revenue to invest in companies that could develop the EOS code into products. What EOS token holders will get out of that is unclear. Some coins have been designed to give users discounts or access to such products. Block.one and EOS have avoided making similar promises.

The company has aggressively courted the public. It announced itself at a May conference in New York City, going so far as to buy ad space on a Times Square billboard. Executives have spoken at myriad conferences and met colleagues and potential clients at “meetups” in cities like London, Amsterdam, Singapore and New York.

Mr. Blumer, raised in Cedar Rapids, Iowa, skipped college to work at a videogaming company in Hong Kong. He later launched a startup dedicated to Indian real-estate listings, then shifted to block.one last year.

After a 12-year stint in Hong Kong, Mr. Blumer is now planning to relocate to London and open an office there, the person familiar with the matter said.

In March, Mr. Blumer hired Mr. Larimer, a digital-currency veteran in Blacksburg, Va., who had previously worked on coin offerings in 2014 and 2016. He left the first, a decentralized trading exchange called BitShares, and the second, which ran a social-media site for bitcoin fans known as Steemit.

“He hasn’t finished a project yet,” said Charles Hoskinson, who worked with Mr. Larimer on BitShares.

Mr. Larimer, who declined to comment, said in a recent video interview that he has made “long-term commitments to block.one” and that he doesn’t expect to leave anytime soon. “Building communities is a lot of work,” he said. “Starting over is not something I do lightly.”

Another key backer is Mr. Pierce, who is described on his LinkedIn page as block.one’s co-founder. In 2005, the company Mr. Pierce ran, Internet Gaming Entertainment, which traded virtual goods used in videogames, bought a similar startup that Mr. Blumer founded while he was in high school.

At age 18, Mr. Blumer moved to Hong Kong to work for IGE. Around the same time that IGE bought Mr. Blumer’s company, it sold a small stake to Steve Bannon and brought him in as an adviser.

Mr. Bannon, who went on to lead Donald Trump’s presidential campaign and served as his chief strategist in the White House, helped in early 2006 to arrange a $60 million investment in the company by Goldman Sachs Group Inc. and two other firms. In 2007 as IGE experienced difficulties, Mr. Bannon replaced Mr. Pierce as CEO.

In June, after the Securities and Exchange Commission warned investors about coin offerings, block.one released a statement saying it is being represented in its token distribution by lawyers at Debevoise & Plimpton LLP and that its sale isn’t open to U.S. residents, citizens and entities. The law firm declined to comment.

The deal is also closed to investors in China, another country that has cracked down on the offerings. While such restrictions are common in the token deals, enforcing them can be tricky since the demand stretches across so many countries.

Bitcoin is useless, unsafe, and dirty, finds withering BIS report

Trust of the digital currencies "can evaporate at any time", the BIS warned

 Ambrose Evans-Pritchard
17 JUNE 2018 • 5:06PM

Cryptocurrencies have no intrinsic worth and are useless as a form of exchange. They entail exorbitant transaction costs. They are very slow. Together they have turned into an ecological nightmare.

They are not backed by the assets and revenues stream of an established state. Most can be rendered worthless by fraud or digital manipulation. They are essentially ponzi schemes that masquerade as citizen currencies beyond government control.

Such are the broad findings of the Bank for International Settlements, the Swiss-based ‘bank of central bankers’ and the leading global authority on the crypto-craze.

While several central banks are examining possible use of blockchain technology for payments systems - such as Canada’s ‘Project Jasper’, Japan’s ‘Project Stella’, and Singapore’s ‘Project Ubin’ - none has yet found compelling reasons to issue their own state-controlled cryptos. 

The report said Bitcoin alone uses as much electricity as Switzerland. This is needed to run the vast network of computers used by ‘miners’ to verify transactions for the distributed ledger. “Put in the simplest terms, the quest for decentralised trust has quickly become an environmental disaster,” it said.

Cryptos are not in fact safe. They are vulnerable to a breakdown in confidence or an attack by those with computing firepower.  “Trust can evaporate at any time because of the fragility of the decentralised consensus through which transactions are recorded. A cryptocurrency can simply stop functioning, resulting in a complete loss of value,” said the report, a chapter in the BIS’s forthcoming annual report.

The BIS says all currency systems face an inherent problem. If they are ‘scalable’ and can expand easily to foster commerce and trade, they can also be debased easily. This is the trade-off that has bedevilled currencies since they began in modern form in China, India, and Asia Minor around 600 BC. Sustained episodes of stable money are rare. “Trust has failed so frequently that history is a graveyard of currencies,” it said.

Room 68 of the British Museum is dedicated to failed commodity coinage and paper currencies, discarded when the political order behind them collapsed or because inflationary abuse destroyed trust. The Kipper-und Wipperzeit (clipping and culling era) of competitive coin debasement by German princes in the early 17th century has pride of place.

The crypto-craze is in one sense a response to the global financial crisis of 2008, and a libertarian backlash against quantitative easing by the US Federal Reserve and fellow central banks, but it does not come up with a viable alternative. Bitcoin and others fail the basic test of a working currency. “The more people use a cryptocurrency, the more cumbersome payments become. This negates an essential property of present-day money,” said the report.

There is a speed limit on the number of transactions added to the ledger at any given point in time. New blocks are rationed by intervals. If the ceiling is hit, the system backs up. “With capacity capped, fees soar. Transactions have at times remained in a queue for several hours, interrupting the payment process,” said the report. In one episode, Bitcoin transaction costs spiked to $48. Visa and Mastercard can together handle 5,600 transactions a second, and margins (not the merchant fee) are wafer thin.

Visa and Mastercard are much faster and more efficient than Bitcoin CREDIT: BIS
The BIS said the crypto-nexus would eventually require a terabyte of computing capacity since ledgers grow by a hundred bytes with every transaction. This could bring the internet to a halt. Moreover, Bitcoin is limited to a maximum of 21 million coins by its protocol. It would be viciously deflationary as a currency. There is no responsible authority to regulate the value of these currencies according to economic need and fluctuations in demand. “Cryptocurrencies simply do not scale like sovereign moneys”. 

The report makes clear that the drawbacks are not just the teething problems of a young technology. They are structural and inherent in the concept. The need to protect cryptos against cheating - “the double-spending problem” - is what leads to the immense and cumbersome apparatus that renders them economically useless.

Nor does the system guarantee “finality of payment”. You can lose your money. “Although users can verify that a specific transaction is included in a ledger, unbeknownst to them there can be rival versions of the ledger. This can result in transaction rollbacks. Cryptocurrencies can be manipulated by miners controlling substantial computing power. One cannot tell if a strategic attack is under way because an attacker would reveal the (forged) ledger only once they were sure of success,” it said.

There is a risk with “forking” when cryptos split. The single month of January alone brought forth Bitcoin ALL, Bitcoin Cash Plus, Bitcoin Smart, Bitcoin Interest, Quantum Bitcoin, BitcoinLite, Bitcoin Ore, Bitcoin Private, Bitcoin Atom and Bitcoin Pizza forks. “Theoretical analysis suggests that coordination on how the ledger is updated could break down at any time, resulting in a complete loss of value,” it said.

Many libertarians turned to cryptos because they do not trust banks and governments. Yet they ended up having to trade through unregulated “crypto wallet” providers or “crypto exchanges”, leaving them at the mercy of digital theft. “Some of these (such as Mt Gox or Bitfinex) have proved to be fraudulent or have themselves fallen victim to hacking attacks.” Almost a quarter of initial coin offerings (ICOs) are opaque ventures or “fraudulent Ponzi schemes”.

The BIS says there is social value in ‘permitted’ blockchain payment schemes such as the World Food Programme’s ‘Building Blocks’ system for handling food aid in the Middle East. It uses an Ethereum protocol. Much can be done with blockchain to improve trade finance and the processing of $540bn of remittances each year. But such “cryptopayment” systems are not to be confused with cryptocurrencies.

That bubble has now definitively burst. Bitcoin has crashed from $19,187 to $6,474 since peaking in December. Most of the leading cryptos have dropped by two-thirds or more, slashing their notional value by at least half a trillion dollars. There is no obvious floor. These currencies are not redeemable. Nothing stands behind most of them. The BIS report is the final authoritative nail in the coffin.
