Bitcoin Price Analysis: Potential Wyckoff Distribution May Spring New All-Time Highs

Bitcoin Price Analysis

A potential Wyckoff Distribution phase is under way as bitcoin continues to climb on shaky ground. Days after having a strong $1,000 climb and nearly reaching $6,000 on most exchanges, we saw a strong rejection of the upper limits of the market as it plunged $600 over the course of a few short hours. Let’s take a look at the macro pattern and draw a few similarities to the Wyckoff Distribution schemes:

Figure_1.JPG

Figure 1: BTC-USD, 2-Hour Candles, Potential Wyckoff Distribution Phase

In order for the current distribution phase to be reliable, there are certain milestones the market must reach. As shown above, we previously established a point of Preliminary Supply, a strong Buying Climax, a knee-jerk reaction into an Automatic Reaction low, and a weak rally that ultimately led to a Sign of Weakness that pushed us down several hundred dollars. The rebound from this low was strong and occurred on very high volume. However, over the length of the rally post-sign-of-weakness, the volume has begun to taper as the momentum indicators are showing signs of bullish exhaustion as it finds its local high at around the $5,700 values.

One of the following milestones for the Wyckoff Distribution phase is one last dip as it tests the previous support around the Automatic Reaction low. As of the the time of this article, the current market trend is showing signs of bearish divergence on the 120-minute candles.  Zooming in closer, we can see clear signs of a potential small reversal:

Figure_2.JPG

Figure 2: BTC-USD, 30-Minute Candles, Waning Momentum

Both the RSI and MACD are showing signs of bullish exhaustion throughout the length of this rally. Any pullback will likely be supported by the Automatic Reaction support level. Historically, this has been a strong point of support and is made more evident on the 60-minute time frame:

Figure_3.JPG

Figure 3: BTC-USD, 60-Minute Candles, Strong Support Zone

The 200 EMA on the 1-hour candles is historically a great support level and provides traders a pulse on the market health. As of the time of this article, the 200 EMA is lining quite nicely with the support zone offered by the Automatic Reaction Zone. A test of these price levels would take a strong push to break and hold below. If the price continues through the Wyckoff Distribution, we can expect a test of the 200 EMA and a subsequent bounce triggering an Upthrust to new all-time highs. As mentioned in the last BTC-USD market analysis, we are trending along a macro channel:

Figure_4.JPG

Figure 4: BTC-USD, 1-Day Candles, Macro Ascending Channel

An Upthrust in this potential Distribution Phase would have a price target testing the upper channel in the $6,200–$6,300 price range.

Summary:

  1. A potential Wyckoff Distribution Phase is playing out.

  2. If the Distribution Phase plays as expected, we will see a test of the 200 EMA and a subsequent spring to new all-time highs.

  3. If an Upthrust to new all-time highs occurs, we can expect a price target in the $6,200s.

What Lightning Will Look Like: Lightning Labs Has Announced Its User Interface Wallet

What Lightning Will Look Like: Lightning Labs Has Announced Its User Interface Wallet

Development of the lightning networkthe highly-anticipated second-layer Bitcoin protocol for instant microtransactions, continues to inch forward.

Lightning Labs, major contributor to the lightning network daemon, lnd, announced its cross-platform Lightning Desktop App last week. The open-source lightning wallet is essentially a user interface (UI) built on top of lnd and powered by Lightning Labs’ new open-source Bitcoin light client, Neutrino.

“This is the first functioning user interface for both sending and receiving lightning transactions with a light client mode,” Lightning Labs CEO Elizabeth Stark told Bitcoin Magazine.

The lightning network is currently being developed by several teams working on different but interoperable implementations of the protocol. Several of these implementations are functional, though only on Bitcoin’s test network (“testnet”): a sort of copy of the Bitcoin network with valueless coins specifically designed for testing new applications and more.

But, while there are already several lightning daemons available for testnet, most are only usable via command line tools. Developers Olaoluwa Osuntokun, Bryan Vu and Case Sandberg collaborated to now extend lnd with the new Lightning Desktop App to provide a user interface.

“I think the big takeaway is being able to visualize this technology and see what an early UI might look like,” said Stark. “It's one thing to be using the command line, as our lnd testers and developers have been, but it's another to be able to download the app. Being able to see this kind of progress is important.”

As part of the announcement, Lightning Labs also introduced Neutrino, the new open-source Bitcoin light client that powers the Lightning Desktop App. As a main benefit, Neutrino users don’t need to download the entire Bitcoin blockchain, which is currently over 140 gigabytes in size. This makes the desktop app much more accessible to regular users who transact small amounts, for which the lightning network is particularly suited. And because Neutrino uses a new method of transaction filtering (client side instead of bloom filters), it offers more privacy than most light clients, too.

The release of the new Lightning Desktop App kicks off a two-week “testing blitz,” as the company described it in their accompanying blog post. Developers are invited to experiment with the desktop app itself, as well as with Neutrino. Further, it makes it much easier for anyone to play around with lnd and the lightning network itself.

“The really cool thing about having our desktop app out there is now there's an easy way for people to interact with all of the apps that developers are building on Lightning, such as Yalls,” said Stark.

After the two-week testing period, the implementation will enter a regular release cycle. Releasing the wallet for Bitcoin mainnet, however, could take a while longer still, Stark explained:

“We're working toward testing and making the software more stable before releasing a beta. This is financial software and its a protocol dealing with money, so we want to ensure people can have a good user experience.”

There is no specific deadline for the beta release, but Stark added that, "The next step is for us to gather feedback from testers and develop it further, along with improvements in lnd and Neutrino."

The open-source Lightning Desktop App code is available on GitHub.

Chaincode Labs to Host a Second Run of Its Month-Long Bitcoin Coding Class

Chaincode Labs to Host a Second Run of Its Month-Long Bitcoin Coding Class

Chaincode Labs, the New York–based development company and major contributor to Bitcoin Core, is organizing a second edition of its Bitcoin residency program in the first months of 2018. The program intends to help developers overcome the steep learning curve associated with becoming a protocol-level contributor to projects like Bitcoin Core. In doing so, Chaincode Labs hopes to help expand Bitcoin’s development community.

“Last year was the first run,” Chaincode Labs developer John Newbery told Bitcoin Magazine. “We’ve now taken the good stuff from that and tried to make it even more focused and useful for residents this year.”

The Residency Program

Chaincode Labs, in collaboration with Matt Corallo — who worked at Blockstream last year but joined Chaincode Labs since — organized the residency program for the first time in September and October of 2016. The next edition will start on January 29, 2018, and will last until February 23.

Newbery himself was one of the attendees of this first residency program. He was later hired by Chaincode Labs and has since been one of the most prolific contributors to the Bitcoin Core project.

Now, he is coordinating the second of two legs of the new program.

“Chaincode Labs exists to strengthen Bitcoin,” said Newbery. “We mostly do that by contributing to Bitcoin Core, but each of us has a lot of freedom to do what we think is important. And the main purpose of this residency program is to try to strengthen the developer community.”

Specifically, courses will cover protocol design, adversarial thinking, threat models and security considerations, as well as address some of Bitcoin’s biggest challenges, like scaling, fungibility and privacy. Attendees will mostly learn by doing and could even start contributing to the Bitcoin Core project during the residency. Throughout the program they will be assisted by the entire Chaincode Labs team — Alex Morcos, Suhas Daftuar, Matt Corallo, John Newbery and Russ Yanofsky. There may also be guest speakers.

Two Blocks

Whereas the first edition of the residency program lasted four straight weeks for all attendees, this time the coding classes will be cut into two two-week phases. Candidates can either pick one of two legs or join both, with room for five or six attendees per session.

The first leg is coordinated by Corallo, who has been contributing to Bitcoin development since 2011.

“Session A is all about getting people to think about the security trade-offs and implications of the technical decisions we make,” Newbery explained. “There’s a lot of thought that goes into all the decisions that are made in Bitcoin, but that nuance is often lost. If we can help people to understand those trade-offs better and be able to communicate them, then perhaps we can raise the level of the conversations we have about Bitcoin.”

The second session will be more focused on the Bitcoin Core project itself, Newbery said.

“Session B is all about getting smart, talented people to start making useful contributions to Bitcoin Core. There’s a steep learning curve to becoming a contributor and if I can help people who want to contribute but have felt daunted or don’t know where to start, then I’ll feel like I’ve succeeded.”

Additionally, Chaincode Labs will organize a series of Wednesday night meetups ahead of the residency program. Contents of these meetups will be similar to the residency program, but these meetups are for participants who live in (or near) New York who can’t dedicate two or four full weeks to attending the residency program itself.

For more information on Chaincode Labs’ 2018 Bitcoin residency program and to find out how to apply, see the company’s announcement and the program website.

Ether Price Analysis: Eve and Adam Could Be Turning Back the Bulls

Ether Price Analysis

Since bottoming out around $200, ether has spent several weeks bouncing back and forth inside an ascending channel:

Figure_1 (15).JPGFigure 1: ETH-USD, 4-Hour Candles, Ascending Channel

For the last month and a half, ether’s trend has been contained within the bounds of this ascending channel, where it has continued its bullish rally. However, today (as of the time of this article) it is starting to make moves to aggressively test the lower boundary. Specifically, as ether tests this channel, it is forming a potential reversal pattern called an Eve-and-Adam Double Top.

Figure_2 (12).JPGFigure 2: ETH-USD, 1-Hour Candles, Eve-and-Adam Double Top

At the time of this article, ether is attempting to break the neckline (the pink dashed line) of the massive reversal pattern. Should ether break this neckline, the measured move from this pattern is a $30 move downward, which would ultimately shove ether outside the bullish ascending channel it has been trending within. The price target of the Double Top breakout would bring the ETH-USD price into the upper $200s.

On a macro scale, ether has support along the following Fibonacci levels:

Figure_3 (12).JPGFigure 3: ETH-USD, 4-Hour Candles, Fibonacci Levels

Should the ascending channel break, the above Fibonacci levels will provide support and will need to be tested in order to prove a bearish continuation. As of the time of this article, the Double Top mentioned in Figure 2 is sitting right on the 23 percent retracement values where it is making attempts at breaking it. There is strong support at these values, so if ether can break and hold below $315, it will send a strong bearish signal to the market.

Should the Double Top complete, we can expect a test of the 38 percent retracement values following the break of the ascending channel. At this time, the 4-hour MACD is showing strong bearish momentum on a macro scale, and the market is picking up sell volume.

Summary:

  1. For weeks, ether has been trending within an ascending channel.

  2. Ether is currently in the process of making a strong test of the ascending channel via an Eve-and-Adam Double Top reversal pattern.

  3. If the Double Top breaks downward, we can expect a break of the multi-week bullish channel and a test of the 38 percent Fibonacci Retracement values.

Trading and investing in digital assets like bitcoin, bitcoin cash and ether is highly speculative and comes with many risks. This analysis is for informational purposes and should not be considered investment advice. Statements and financial information on Bitcoin Magazine and BTC Media related sites do not necessarily reflect the opinion of BTC Media and should not be construed as an endorsement or recommendation to buy, sell or hold.

Blockchain-Focused Presentations to Watch at Money 20/20 in Las Vegas

Blockchain-Focused Presentations to Watch at Money 20/20 in Las Vegas

Money 20/20 Las Vegas is only a few days away. The event, to be held on October 22–25, 2017, at the Venetian, will be packed with people from the top tiers of banking and finance looking to learn more about the future of money.

One thing is for sure, blockchain technology will play a key role in that future. Since 2014, the financial event, which will attract more than 11,000 visitors this year, has devoted an entire track to blockchain topics. Originally, the track was called “Bit(coin) World,” but that changed as conversations shifted to Bitcoin’s underlying ledger technology.  

For blockchain enthusiasts struggling to sort through the 450 presentations at Money 20/20, the following is a breakdown of the blockchain track and other blockchain-related talks at the event.

Blockchain Tuesday

Tuesday is the main day for blockchain programming at Money 20/20. Kicking off the blockchain track will be Adam Ludwin, CEO and co-founder of Chain, a company that provides blockchain solutions to banks. Ludwin’s talk will center on whether crypto-assets are in a sort of ‘90s bubble or if something real and substantial is happening beneath the hype.

To give a sense of how fast things are moving, bitcoin was around $650 at last year’s Money 20/20, when one panelist at the event, then Blockstream developer Eric Martindale, predicted bitcoin would increase 10x in value over the next 12 months. His prediction was nearly spot on. Bitcoin reached more than $5,800 just last week.

With crypto-assets hitting all time highs across the board, the new funding model known as initial coin offerings (ICOs) have raised $2.2 billion this year alone. Yet, amidst the enthusiasm, the threat of increased regulations hover like a dark cloud. Last month, the SEC brought the first charges against two so-called ICOs in what may be just the beginning of a long-anticipated crackdown.   

Four more panels on Tuesday will focus on issues like: What problems are private blockchains solving? Are ICOs here to stay or are they just a passing fad? What threats do regulatory agencies pose to ICOs? And, how will blockchain technology potentially transform stock exchanges? These panels will include experts from companies like Bloq, Kik, Fenbushi Capital, AngelList, Pantera, JP Morgan Chase, R3, Hyperledger, Nasdaq, and the London Stock Exchange Group. 

In between those, Arthur and Kathleen Breitman will talk about their new smart contract platform Tezos. The project raised $230 million in an ICO in July.

Tezos is a proof-of-stake cryptocurrency and smart contract platform built in the functional language OCaml. Eventually, Tezos’ goal is to compete with the likes of Ethereum and Cardano, another emerging platform. A primary feature of Tezos is its formal governance scheme, where coin holders get a say in how the protocol evolves.

It will be interesting to see how Tezos plans to differentiate itself in an increasingly competitive landscape.

Finally, Bobby Lee, CEO and co-founder of BTCC, China’s longest running bitcoin exchange, will share war stories on what it has been like operating an exchange in the biggest payments market in the world.

He should have a good story to tell, given that China’s central bank recently cracked down on digital currency exchanges, causing BTCC to halt all China-facing trading last month.  

Other Talks

Two other blockchain-related talks will take place at Money 20/20 on Monday. Bridget van Kralingen, who leads a group called “Industry Platforms” at IBM will talk about how AI, blockchain and cloud computing are converging to create better customer experiences.  

Bill Barhydt, co-founder and CEO of Abra, a cryptocurrency wallet, will give a keynote announcement on Abra’s “next chapter.” Barhydt attracted some attention recently when he chose actress Gwyneth Paltrow as an advisor for Abra in “Planet of the Apps,” a kind of “Shark Tank” for iOS apps.  

Also on Tuesday, BitGive Foundation, a nonprofit that receives bitcoin donations for charitable causes, will be giving a presentation on GiveTrack, its blockchain-based system for tracking donations in real time.

The topic of blockchain applications is sure to come up in plenty of other talks and discussions at Money 20/20, such as this one on financial inclusion on Sunday and those centered around pressing issues like security (the event comes on the heels of the Equifax breach), identity and more.

GoldMint and the Future of the Gold Trade

GoldMint Header

As a precious metal, gold is often associated with wealth, prestige and power. And as a commodity it has long been considered a prized asset for scores of investors throughout the world.

Beginning with bitcoin in 2009, cryptocurrencies have also seen their prominence rise due to some of the qualities that they share with gold, the most prominent of which is their scarcity.

One of the big issues that has continued to hamper gold as a physical asset is that it can often be difficult to transfer from one place to another. Moreover, the managing and handling of gold can be quite logistically challenging and laborious.

With the emergence of today’s digital age, a startup called GoldMint is seeking to alter this trend with a new means of exchange for physical gold, with transactions occurring over a blockchain-based platform.

This gold-based venture aims to assist investors and traders in managing volatility risks and gaining competitive commissions on commodities sold via GoldMint to financial institutions, pawn shops, and other business and individual stakeholders.

GoldMint’s platform will leverage the private and individual gold trading market, including potentially the management of larger physical stocks such as those in central banks. It will also deliver an electronic payment solution tethered to physical gold, as well as a gold-backed peer-to-peer lending system.

The GoldMint ecosystem is fueled by two types of tokens, GOLD and MNT.

The GOLD cryptoasset is an investment tool that is 100 percent backed by physical gold and/or an exchange-traded fund (ETF). One GOLD token represents one ounce of gold on the London Bullion Market Association (LBMA).

MNT  is GoldMint’s native cryptocurrency, which is used to confirm GOLD cryptoasset transactions. For GoldMint miners, the amount of MNTs reflects how many assignments, or transaction blocks, they can accept.

Fostering Digital Gold Trading

There are two options for trading GOLD for fiat or cryptocurrencies. First, there is a method for seeking a GoldMint-guaranteed buyback. And second, a loan can be requested. For either option, the process is as follows:

      Through the use of a special app which is not yet available, GOLD can be transferred as collateral to a designated GoldMint account.

      GoldMint utilizes the current price of gold, as set by the LBMA, to fix the rate of a loan.

      GoldMint requires the customer to undergo its know-your-customer (KYC) process as well as consent to GoldMint’s loan terms to receive the loan. Various repayment options for the loan amount and the means of repaying it are then offered.

      If a customer defaults on repayment, their GOLD cryptoassets are transferred to GoldMint.

GoldMint also has a process for converting gold into GOLD tokens and reconverting these tokens into gold for cross-border passages. This is designed to alleviate the hassles associated with carrying gold from one country to another, often resulting in untold expense and aggravation. By converting gold into GOLD, this hassle can not only be avoided, but a person can retrieve 100 percent of the value of their gold at the end of their travels.

“Custody Bot” is GoldMint’s decentralized storage unit, which computationally identifies and stores gold jewelry, small ingots (up to 100 grams) and coins. In this case, it functions as a DApp, a decentralized application that runs rapidly and efficiently without the need for a third-party intermediary to control it. Through the use of cutting-edge technology, Custody Bot inspects and assesses the value of incoming gold to ensure its purity and quality.

GoldMint ICO Accelerates Ahead

On September 20, GoldMint launched its initial coin offering (ICO), allowing users to send bitcoin or ether and receive MNTP (MNT pre-launch) tokens, issued on the Ethereum blockchain at a price of $7 per token.

The value of these tokens is expected to grow, because MNT is limited in its supply and is used in the Proof-of-Stake (PoS) consensus algorithm. Participation in the GoldMint crowdsale involves more than the purchase of cryptocurrencies. It involves a stake in the consensus algorithm that will be utilized by the GoldMint blockchain post-launch.

Owning MNT allows users to achieve 75 percent from commissions earned when transactions are validated through the GoldMint blockchain. The number of MNT tokens owned determines the number of transactions that can be validated.

Scaling Bitcoin Announces This Year’s Program and a New Developer Bootcamp

Scaling Bitcoin Just Released This Year’s Program and a New Developer Bootcamp

Today, Scaling Bitcoin, the international engineering conference focused on Bitcoin and blockchain research, released its program for the 2017 edition. The conference, to be held in Stanford, California, in the first weekend of November, will also introduce a new side event this year: Bitcoin Edge, a bootcamp for starting Bitcoin developers.

“The program is extremely interesting because it delivers cutting edge research on different blockchain scalability approaches, fungibility, consensus, data propagation, alternative techniques for handling blockchains and many other topics,” said Anton Yemelyanov, chair of the Scaling Bitcoin Planning Committee.

Scaling Bitcoin Stanford

After events in Montreal, Hong Kong and Milan, the fourth edition of the Scaling Bitcoin conference is taking place at Stanford University on November 4 and 5 of this year.

Where the first two editions of Scaling Bitcoin were mainly focused on scaling and scalability, the third edition broadened the scope of the conference to include a more diverse set of topics. This trend will continue in Stanford, where talks will range from highly technical topics concerning privacy and fungibility, to fee markets and fee estimation, censorship resistance and more.

“Bitcoin is the origin of all distributed ledger technology,” said Yemelyanov. “Scaling Bitcoin has been fortunate to act as a vehicle for bringing the audience technologies such as Segregated Witness and MimbleWimble, all of which have been adopted or incorporated into various blockchain projects. We hope that other material presented by our participants will be of similar value and help the industry advance the research and development of blockchains.”

Yemelyanov added that another key goal for Scaling Bitcoin conferences is to bring engineers and other technical minds together in a physical space where they can discuss their work in person.

“It is through collaboration where a lot of ideas are born and have potential of becoming reality,” he said.

Bitcoin Edge Dev++

In addition to the conference itself, Scaling Bitcoin is also introducing a two-day technical bootcamp for experienced developers getting into Bitcoin: Bitcoin Edge.

This nonprofit initiative is an effort to help scale the development capacity of the industry, Yemelyanov explained:

“One of the approaches of helping the industry scale is to scale the much needed development capacity of the industry. There is a clear talent deficit and we are trying to help all industry participants by running a nonprofit workshop that will allow developers to gain complete understanding of primitives that comprise Bitcoin and blockchains in general and be able to start working in this field.”

Bitcoin Edge will be led by well-known Bitcoin developers and academics Anditto Heristyo, Ethan Heilman, John Newbery, Karl-Johan Alm, Nicolas Dorier, Thaddeus Dryja and Jimmy Song. They’ll introduce participants to a range of technical Bitcoin-related topics, including Elliptic Curve cryptography, transaction structures, difficulty calculation and adjustments, and much more.

This workshop will take place on the November 2 and 3. For more information on the Bitcoin Edge initiative, visit bitcoinedge.org.

Yes, Bitcoin Can Do Smart Contracts and Particl Demonstrates How

Particl Thumb 3

The Bitcoin blockchain is not known for its ability to enable smart contracts. In fact, most developers creating smart contracts use a different blockchain, like Ethereum.

 

But the truth is that the Bitcoin protocol can be used to create smart contracts. Particl.io, the blockchain eCommerce platform, is doing just that by using Bitcoin-based smart contracts to manage funds in their trustless escrow: Mutually Assured Destruction (MAD) escrow.

 

For Particl, Bitcoin provides the ideal mix of smart contract functionality — enough to make smart contracts easy to implement but without the security and privacy risks of a more complicated platform like Ethereum.

Smart Contracts Overview

A smart contract is an agreement that can be enforced through a blockchain. Rather than relying on trust or a legal framework to ensure that each party that enters into a contract will adhere to its terms, you can use the blockchain to create a contract that is automatically enforced, between two people, in a decentralized fashion.

 

Ethereum has become the most popular blockchain for creating smart contracts. One of the major design goals of the Ethereum platform was to support smart contracts. From the start, this set Ethereum apart from Bitcoin, which was created first and foremost as a digital currency platform.

Smart Contracts on Bitcoin Codebase

As the Bitcoin protocol has evolved, it has gained support for smart contracts. Smart contract functionality is not as programmable and extensible on Bitcoin as it is on Ethereum. However, using features added to Bitcoin through improvement proposals, certain smart contract functionality can be achieved through Bitcoin scripting.

 

For Particl, the most important smart contract feature in Bitcoin is the OP_CHECKLOCKTIMEVERIFY opcode, which was introduced by Peter Todd as Bitcoin Improvement Proposal (BIP) 65. The opcode makes it possible to write scripts that prevent funds in a multi-signature wallet from being spent until a certain signature pattern is implemented or a certain amount of time passes.

Particl, Smart Contracts and MAD Escrow

MAD escrow is a technique that effectively prevents fraud in a transaction without requiring the oversight of a third party. In a MAD escrow contract, a buyer and seller both place funds into escrow. The seller starts by depositing an amount they want the buyer to match to symbolize a virtual handshake. This could be between 0 and 100 percent of the item’s purchase price. The buyer then deposits an amount equal to the handshake amount plus the price of the item they are buying. The escrowed funds are not released to anyone until both parties confirm that the transaction has been completed satisfactorily. The technique prevents either party from profiting through cheating in a transaction.

 

Particl uses the BIP 65 opcode to enable MAD escrow contracts by locking funds in a multi-signature wallet until all of the parties sign off on the transaction. With this approach, buyers and sellers on Particl’s ecommerce platform can operate without worrying about fraud or paying unnecessary fees.

 

They also don’t have to sacrifice privacy because no third party is involved in the transaction. Furthermore, and perhaps most significantly, because there is only basic scripting involved, security concerns are minimal.

 

Particl’s approach to MAD escrow smart contracts is arguably better than building smart contracts on a platform like Ethereum. While Ethereum provides more extensible support for smart contracts, that flexibility comes with a higher risk of security and privacy threats. The more code that goes into a smart contract, the greater the risk of introducing a vulnerability that could enable an intrusion.

 

Ethereum might be a strong foundation for writing very complex smart contracts, or ones in which security and privacy are not priorities, but Bitcoin provides a simpler and more reliable scripting framework for the private escrows that Particl requires.

Contributing to Bitcoin’s Future

 

Particl’s choice of Bitcoin as the backbone for its smart contracts is also a reflection of the team’s efforts to build a completely private platform on top of the Bitcoin codebase, arguably the most secure, battle tested and contributed to protocol on the market.

 

There are many dozens of Bitcoin-based blockchain projects out there, but most are simply building cryptocurrencies forked from Bitcoin. They’re not taking advantage of Bitcoin’s potential to create the foundation for a completely decentralized platform that supports a multitude of DApps and programmable functionality.

 

In this sense, Particl is helping to ensure that Bitcoin’s future will evolve more than just creating another cryptocurrency. Privacy enhancements Particl has already implemented onto the latest Bitcoin codebase such as Confidential Transactions and RingCT can just as easily be one day adopted upstream to further harden Bitcoin.
