If you have been in the world of cryptocurrencies for a long time, you should have experienced the evolution of the business models. In the initial phase, there were many business models linked to advertising.

The already known “faucets”, and the PTCs (Paid To Click) were a viable way of acquiring small portions of cryptocurrencies to go deep into this world. Then multiple problems arrived and only the best projects have survived.

And today we introduce you one of those projects that have adapted and improved over time to continue having a place in the saturated world of internet advertising: BTC Surf.

What is BTC Surf?

BTC Surf is a community, developed by the professionals of the Spanish Blockchain Association.  Anyone can register for free and enjoy various benefits (depending on the type of membership).

Depending on the activity in the community you can earn Bitcoins, you can earn traffic for your web portal or meet new portals and investment opportunities.

Advertise forever

Members can advertise with a single payment and enjoy the service for a lifetime. In this way, the advertiser will be able to receive traffic from real users throughout his life and thus increase his yields.

Those users who do not wish to advertise can also earn while they see ads from the partners that are advertised, and also know quality alternatives that are being promoted by the other members of the community.

Other sources of benefits: The Affiliate System

Apart from the normal activity of the community, it can also be earned by recommending the platform to other users, with which we will subsequently earn a percentage of the profits that are generated later thanks to that user.  The BTC surf affiliate network is up to 11 levels deep (for the highest memberships).

Clarity with financials

The distribution of money generated by the community is a clear system designed with transparency to guarantee confidence in the system.

The distribution is as follows:

• 50% – Membership plan distributed in 11 levels.

• 20% – External Surfing Promotion for all advertisers, generating visits from other traffic sources.

• 10% – Weekly Bonus.

• 10% – Random bonus per activity.

• 10% – Management and maintenance of BTCSURF systems

The newest: The pool

The latest and most innovative service that BTC Surf partners offer us is the “pool”.  When we talk about pool we do not mention what we all know as a mining pool.  A pool, in general, is a group of people (or companies) that come together to offer a service or take advantage of a business opportunity.

In this case, the Pool offered by BTC Surf is intended to exploit the affiliate network market.  With the contributions of the members of the community, the affiliate networks of top quality portals within the Bitcoin universe and cryptocurrencies are exploited.

Next, let us show the chart of profitability of the pool.

As can be seen in the above graph, profitability ranges between 0.20% and 1% of daily gain.  Which is a fairly profitable investment if we consider the tremendous competition in the internet advertising market.

In addition, the pool evolves as the community decides since they will make investments in the portals that the members themselves decide: a tool for the community!

Conclusion

BTC Surf is a mature, profitable community that continues to innovate to offer profitable services for its community, as evidenced by the recent launch of its commission POOL.

Crypto exchange CoinDeal has announced the renewal of its advertising agreement with the Wolverhampton Wanderers, a major English football team. The sponsorship means that CoinDeal will continue to sustain a brand presence within the mainstream sports world, a rarity for a bitcoin-focused company.

CoinDeal, which operates a cryptocurrency exchange that has so far catered to European traders and recently announced plans to expand into the United States, has been an official partner of the Wolverhampton Wanderers (known to many fans as, simply, the Wolves) since July 2018. Through the partnership agreement, CoinDeal’s logo appears on the uniforms of the Wolves, one of England’s Premier League teams.

This week, CoinDeal announced the renewal of its advertising sponsorship, saying that the deal will continue through the 2019–2020 football season.

Wolverhampton Wanderers Training

In a statement, CoinDeal said that it decided to continue the sponsorship because it has “turned out to be a great success for CoinDeal” during its first year, with the company’s logo being viewed at least 350 million times by television and online viewers of Wolves games.CoinDeal also released a video with details on the renewed Wolves partnership:

Bitcoin Advertising and the Mainstream Sports World

From the perspective of the cryptocurrency and bitcoin ecosystem as a whole, CoinDeal’s decision to continue advertising with the Wolves is significant. Advertisements for bitcoin-related businesses are few and far between not just within the sports world, but within mainstream offline contexts in general. You may expect to find ads for bitcoin businesses on the web, but seeing the logo of a crypto exchange on the sleeves of a major European football team is more surprising, at least at present.

In this sense, CoinDeal is helping to close the gap between the bitcoin ecosystem and the world of mainstream media and advertising. For now, CoinDeal’s reach in this regard may be limited primarily to English football fans, but that will perhaps change as CoinDeal continues to expand its operations beyond Britain and Europe.

Bitmain may not have a stock of their newer 7nm chips for the faster SHA256 ASIC miners, but they apparently have more of the old chips to push new miners, so hence the Antminer S9 SE is born. It is a 16 THS Bitcoin ASIC miner with built-in power supply(?) and a 1280W power consumption (80 J/TH power efficiency). The price of the new Bitmain Antminer S9 SE ASIC miner is set at $351 USD with the first batch to go on sale today scheduled for shipping in 21-31 July, 2019.

Although this may be far from the latest offerings in terms of hashrate, miners like the “new” Antminer S9 SE might be interesting for some people due to their low price and if they can be combined with low priced power it might be a good opportunity. The used market for Antminer S9 ASICs is booming lately due to the price of Bitcoin going up, so we see demand for the new miner for sure. Of course it also depends on the amount of units that Bitmain can deliver…

While crypto fanatics have been buzzing with news about bitcoin price surges and Facebook’s introduction of its digital currency libra, the Bitcoin 2019 conference brought together some of the most significant people in the BTC community for a two-day event to discuss the current and future state of Bitcoin. 

Among the conference speakers were Scott Stornetta, chief scientist at Yugen Partners, and Blockstream CEO Adam Back, the creator of Hashcash.

These two crypto scientists are particularly notable because they were directly cited by Satoshi Nakamoto in the Bitcoin white paper. At Bitcoin 2019, they came together for a discussion with Bitcoin YouTuber Naomi Brockwell about their contributions to the creation of Bitcoin and where they foresee the original cryptocurrency going in the years to come.

Stornetta’s Contributions to the Development of Blockchain

Stornetta co-authored three papers cited in Bitcoin’s white paper and was one of the first people working on creating a system that did not require people to trust a central authority. In the early days of Bitcoin, Stornetta realized there was a problem with recording transactions, so he suggested the creation of immutable records in order to track all bitcoin transactions.

“We’re going to not be able to know the difference between an old bit and a new bit, and all of the world’s records are going to be in bits, and that’s going to create a crisis of credibility,” as Stornetta described the problem during his conference panel. 

According to Stornetta, he and Stuart Haber, who is also credited with the creation of blockchain technology, were struggling to solve the problem, so they decided to create a publication that would prove it is impossible to build an immutable record without a central authority. In writing it, Stornetta said they were able to figure out how they could build an immutable record with the use of a blockchain. 

Back’s “Proof-of-Work” Concept

In 1997, Adam Back introduced Hashcash, a “proof-of-work” system that would help users of the internet detect and avoid spam email. Hashcash worked to ensure users were only accepting emails from others who provided proof that an effort was made to send the email.

The “proof-of-work” concept was carried over into the world of Bitcoin to enable competitive mining of blocks. By using a trial-and-error method to mine bitcoin, miners that are able to verify proof of their work and successfully mine a block are rewarded with bitcoin as payment. 

“Satoshi made use of the hashcash idea to create the mining,” Stornetta said. “It’s easy to see in hindsight huge incentives were needed to kickstart (bitcoin).” 

The Future of Bitcoin

For Stornetta, the future of Bitcoin is broad and diverse. Stornetta told the audience at the conference that he is a “fundamental believer” in crypto technologies and their ability to level the playing field. 

“I am not a crypto anarchist, but I certainly am a crypto libertarian, and I think we are going to get the world that we want and that we deserve, we just need to find a path that leads from A to B,” Stornetta said. 

Stornetta said he believes distributed ledger technologies will continue to advance and diversify in the future, and that he sees a potential for other currencies besides bitcoin to flourish. 

“It doesn’t all just have to be about money, of course,” Stornetta said to the crowd. “I’m a big fan of the distributed ledger and how that can create quantization and tokenization of assets … I just think we’re gonna see such a broadening and diversification of this.” 

“A New Paradigm”

Back also touched on the quick development of cryptocurrency technologies and the challenges of keeping up with the pace of new ideas and implementations of them, even for technical people. Back discussed how there are still areas of innovation that have yet to be realized. He further noted that blockchain and bearer electronic cash are new building blocks that have implications with smart contracts. 

“Basically, it’s like picking up a new programming language with a new paradigm, and it takes a lot of people to natively understand it and reach the conclusion of what kind of conclusions you can build with it,” Back said.

Back mentioned the development of the Lightning Network and state chains to further his point about how advancements within crypto technology are being made at a rapid rate. He also discussed his reasoning for why multiple cryptocurrencies may not be a necessity in the long run. 

“In terms of coins, I tend to view it as sort of like TCP/IP — that there’s one interoperable standard,” Back said. “Any kind of innovation can be adopted in layers or, ultimately, people can import Bitcoin’s UTXO set to another data structure if a new data structure is found.”

On March 9–10, 2019, the Massachusetts Institute of Technology hosted a two-day event, the MIT Bitcoin Expo 2019. Put together by the student-organized MIT Bitcoin Club, the conference welcomed more than just Bitcoin voices from every corner of the industry. One of those voices was that of U.S. Securities and Exchange Commission (SEC) Commissioner Hester Peirce.

Peirce sat down with Gary Gensler, ex-chairman of the Commodity Futures Trading Commission, senior lecturer at the MIT Sloan School of Management and senior advisor to the director of the MIT Media Lab, to discuss the progress of the SEC’s efforts to regulate the cryptocurrency industry. Notably, Gensler and Peirce launched into a discussion on what regulators can do better to protect investors from fraud and malicious actors.

Before the debate began, both Gensler and Peirce expressed their appreciation for the emerging technology. “It’s a new way to have tamper resistant data amongst the consensus of multiple parties,” Gensler said. “My research is mostly around the business of blockchain technology and … trying to find where are the real use cases where traditional data structures don’t work as well.”

Peirce expressed her own support for the space in relation to the SEC’s ongoing efforts to properly regulate it. “We have rules on the books that we have to enforce, but on the other hand, we don’t want to stop people from doing things that are going to make society a better place to live, that are going to make people’s lives easier, and enable people to interact in ways that they have not been able to in the past.”

Later in the presentation, the two veteran regulators went on to discuss what the government can do to protect investors by possibly regulatinged cryptocurrency exchanges.

Gensler believes that “exchanges are the gateway to get good public policy, particularly around AML laws, but also around investor protection.” He continued, “In essence, that there’s not a manipulated market with frontrunning and manipulation with the order books and the like.”

The discourse was ongoing, and the most significant takeaway was that regulators like Peirce and the SEC acknowledge that, again, perhaps the current system of rules don’t apply perfectly. How could securities-based regulations be placed on all cryptocurrencies, even those that are officially defined as not securities?

The SEC, according to Peirce, is working on what may be an alternative set of rules for exchanges that do not violate the rules of listing unregistered securities. Bitcoin, which is not a security, falls neatly into this alternative rule set. And, though it is currently unclear what the exact precedents will be, Peirce’s thoughts around the subject at MIT’s latest Bitcoin Expo were nothing short of encouraging for Bitcoin’s regulatory future.

“People regulate each other in their interactions with one another, and that’s sort of the whole purpose of the Bitcoin idea … that it would be this community that would be able to regulate itself. So as problems arise, people in the community are thinking about how to deal with those problems.

“I think these markets could regulate themselves if we lived in a world that allowed that,” Peirce added.

Peirce has made similar remarks about the SEC’s awareness of the Bitcoin community’s tendency to self-regulate in the past.

Gensler and Peirce also discussed the topic of initial coin offerings (ICOs) and what is being done to provide clarity to people participating in the once-booming phase. Peirce went on to explain that the SEC has already provided some clarity for investors who want to create a company, raise funds from investors and then distribute returns based on the company’s performance. For these individuals, the existing securities rules will apply to their tokens.

There are, however, the countless number of tokens that claim to be used as a utility on the network they belong to, but originate through an ICO in which they accept funds from investors in exchange for these tokens. There are still a plethora of unanswered questions around these.

“That’s where we need to do a better job,” Peirce said, “in providing guidance in how does it change from one thing to another.” Eventually, she said, the SEC wants to remove the big gray cloud hanging over these project’s heads.

Overall, the uplifting theme of the entire discussion could be summarized by an exchange between Peirce and a member of the audience, addressing the current system that discourages equal opportunity in retail participation.

The audience member asked, “It may be hubristic, but many of us are not independently wealthy and we still believe we can make good investment decisions, and right now we’re excluded from participating. How can we move the accredited investor laws away from wealth thresholds and toward something that’s far more reasonable and accessible to mainstream investors?”

“Our accredited investors rules … I personally think those rules are not consistent with what this country is about,” Peirce admitted, “which is about people taking opportunities, taking their talents and intelligence and applying it to make their lives better. We’ve put this artificial barrier in place so that people can’t do that.”

As far as whether or not these opinions will translate into legislature, time will tell. The entire MIT Bitcoin Expo 2019 livestream recording can be viewed here.

hodlhodl prediction.jpg

Hodl Hodl, a peer-to-peer cryptocurrency exchange, has announced that it is launching a prediction market on Bitcoin. Slated for launch in the spring of 2019, it would be the first Bitcoin-based prediction market to go live on Bitcoin’s mainnet.

A prediction market is a novel application of blockchain technology. The betting platforms allow users to secure odds, futures and outcomes with smart contracts. Two users place funds (traditionally, ether) into a smart contract to bet on futures for any given outcome; when the outcome arrives, the smart contract automatically pays out to the winner.

Most prediction markets are built on blockchains with a more flexible smart contract language, like Ethereum. Augur, for example, pioneered the model when it launched in July 2018 as the first decentralized prediction market to make use of Ethereum’s ERC-20 token contract. Other prediction markets have followed suit, including Gnosis on Ethereum and Bhodi on QTUM.

Despite Augur’s frontrunning status, Hodl Hodl believes that it can improve on aspects of the platform’s operations — specifically, in its solution to the “oracle problem:” How, for example, does the smart contract know who wins the World Cup, if bitcoin closed above $3,850 by midnight on March 8, or who won an election?

You need software and people (oracles) to feed this data to the smart contract. The inherent counterparty risk becomes an issue of trust and accuracy: How do you keep oracles honest and how do you verify their inputs? To mitigate this risk, Augur leverages decentralized oracles. Multiple users are in charge of inputting data/results to make sure that the reported results of an outcome are accurate and that the smart contract pays out to the winning prediction.

Decentralizing the sources of inputs, in theory, should ensure that every prediction market’s payout is consistent with real-world outcomes, but some opponents argue that there aren’t enough participants on these decentralized platform to prevent bad actors from gaming the system.

“We're approaching this slightly differently,” Roman Snitko, Hodl Hodl’s chief technology officer, told Bitcoin Magazine. “The oracle [is] the two parties participating in a contract. In case of a dispute, Hodl Hodl steps in with its third key and is able to influence the decision.” It is the company’s belief that, whereas a decentralized system for judging bet outcomes can be influenced by bad actors, a peer-to-peer contract might be more ironclad.

To contrast with the established model of prediction markets, on February 27, 2019, Hodl Hodl announced their own prediction market, the first to be built on the Bitcoin blockchain. Additionally, their oracle system, according to Snitko, “is not decentralized — we have a central server. But we're non-custodial. In the case of a prediction contract, both parties lock bitcoins in a 2-of-3 [key] escrow. Both of their keys are required to send the locked funds somewhere — unless they both sign the release transaction, bitcoins cannot be moved from there.”

Under this system, there is no incentive to try and dispute the outcome of a bet, as the funds will not be released if the two parties disagree. If someone fudges the results of an outcome and both parties claim the coins, a tiebreaker ensues.

“In case of a dispute,” said Snitko, “both parties may actually never come to a decision to unlock the funds, in which case Hodl Hodl can step in and use its third key along with one of the parties keys to unlock funds in their favor. Hodl Hodl cannot unilaterally move bitcoins to wherever it wishes to because we still need one of the user's keys (which we don't have) to sign the release transaction.” The company warns, however, that forcing the impartial mediator to step in may negatively impact a user’s ability to convince other users to enter new contracts.

One solution to this problem could be having a third party mediator who, unlike Hodl Hodl, is not a stakeholder in the situation in any regard. Snitko is entertaining the idea, telling Bitcoin Magazine that “in the future we might have a user group called ‘mediators’ who would take on the role Hodl Hodl currently performs in case of a dispute — with a third key.” He added, however, “it's probably wrong to call that party an oracle, as the decision is not made by that single party.”

“At launch,” he said, “we want to keep it as simple as possible and then see what needs to be improved.”

Bitcoin Magazine asked Hodl Hodl to explain how its reputation system works but has not yet received a response.
