Bitcoin Price Takes a $200 Tumble After Eight-Day Highs


Having dropped back from eight-day highs hit this morning, bitcoin (BTC) price could be in for a bout of consolidation before further upside unfolds.
The cryptocurrency rose to $6,596 earlier today on Bitfinex – the highest level since Sep. 6 – adding credence to the short-term bullish reversal signaled by the symmetrical triangle breakoutearlier this week.
However, despite the strengthening bullish case, BTC quickly lost around $200 soon before press time. As if writing, BTC is changing hands at $6,450, having printed an intraday low of $6,355 a few minutes ago.
While the sudden price pullback could force investors to question the sustainability of the corrective rally, the short-term technical charts continue to show that the path of least resistance is on the higher side.

Hourly chart

BTC's retreat from the highs near $6,600 is likely associated with the bearish divergence of the relative strength index seen in the hourly chart.
Indeed, the RSI has adopted a bearish bias, but it is premature to call an end of the technical recovery, as the major moving averages (MAs) – 50-hour, 100-hour, and 200-hour – are still trending north in favor of the bulls
More importantly, the key MAs are capping the downside at press time. This leaves scope intact for a recovery to resistance at $6,800 (multiple daily highs).

Daily chart

On the daily chart, BTC closed (as per UTC) above the 10-day MA yesterday, neutralizing the bearish view put forward by the rising wedge breakdown on Sept. 5.
However, the short-term MA is still sloping downwards. This, coupled with the bearish RSI divergence on the hourly chart could keep the cryptocurrency range-bound for the next 24 hours or so.
It's worth noting that technical recovery usually gathers speed after the short-term MAs bottom out – unless, of course, there is a major positive fundamental news.

View

  • BTC has retreated from eight-day highs, but the technical recovery is still intact.
  • The cryptocurrency could consolidate around $6,400 in the next few hours before resuming the journey towards $6,800.
  • A UTC close below the trendline connecting the June low and Aug. 11 low would put the focus back on the rising wedge breakdown witnessed earlier this month and could yield a drop below $6,000 (February low).

Bitcoin and Cryptocurrencies rebound at the end of weekly trading and talk about regulation in Europe


Cryptocurrencies rebounded on Friday as the CEO of Gibraltar Blockchain Exchange criticized the lack of regulation in the EU.

Overall currencies were highly valued, with a market capitalization of $ 199 billion at the time of writing, compared to $ 197 billion on Thursday.

  • Bitcoin rose 0.13% to $ 6,467.60 on the Pittsburgh Stock Exchange as of 13:04 GMT.
  • The Etherum or Ether, the second-largest alternative currency by market value, rose 5.02% to $ 208.52.
  • XRP, the third largest virtual currency, rose 0.52% to $ 0.27610 .
  • while the Litcoin recorded $ 53.664, down 0.20%.
Nik Kwan, chief executive of the Czech stock exchange in Gibraltar, said the lack of regulation in the EU had a negative impact on industry.
"The absence of coded regulations at the EU level is a deterrent to collective innovation and will continue to hinder the use of technology by major financial service providers in the future," he told Cryptovest.
His comments came after news this week that regulators in the EU are waiting for the digital currency to be organized so regulators can analyze the market. With the popularity of virtual currencies rising, governments around the world are having difficulty responding. So far there are no comprehensive laws in the EU regarding the processes of cryptocurrencies and blockchain, the technology behind the Betquin.
On Wednesday, French legislators passed a law setting guidelines for initial currency offers, enabling the financial regulator of the AMF to approve and issue permits to companies offering ICO offices.


Yahoo and Cryptocurrencies


In other news, Yahoo broke into the world of Cryptocurrency, and after that, the company reported statistics on Bitquin Cash and the Atrium Classic, although the ability to trade is limited to the mentioned currencies.
 The platform added four cryptocurrencies available for circulation are Betquin and Lithium Ethylene

What Is An ICO Token And How Does It work?

What’s the definition of crypto token? 

It's an entity with a value specified by the eminent. If it's a fashion startup, one token can be equal to one dress or a yearly license of a software in case of a hi-tech startup. You even can issue tokens of yourself and a token holder will be able to buy an hour of your work with the token. You can “tokenize” everything.

What’s the difference between cryptocurrency coins and tokens? 

This is a difficult part. The easiest answer: tokens are not a currency. You don’t need to create a Blockchain to issue tokens, which is a must-have for a cryptocurrency, but you use an existing one (usually Ethereum, which was originally created as a platform for smart contracts and evolved to be a currency).
A combine sorting bitcoins
A coin is a money equivalent, something that defines value and serves as a value transfer.
A token is a symbol of a contract, the value does not depend on mining, gold price or any dynamic market criteria. A friend of mine once gave me a note saying that he will always make me a coffee on demand. He still does it, after 10 years, it was a heck good token!

What is a token contract and how does it work? 

Ok, a token is not a coin, got it. But still, something should regulate it’s transaction, value etc? How does that work? You do need a platform for it. Let’s take Etherium as an example, since its one of the most popular platforms for smart tokens.
Here is the full contract cycle:
  1. Tokens creation: a company writes the basic rules (tokens amount, token value, special conditions). Once created the platform will serve as a very smart notary for all the future transactions, making sure all the conditions are carried out.
  2. Tokens acquisition: when somebody wants to buy a token, the process is really similar to buying a coke in a vending machine. You approach a machine, drop the coin and push the button “coke” (choose the token you want to buy). The machine checks if there are “cokes” in stock and if you are eligible to buy it. If everything is fine- you get your drink (or token in our case). The machine says “have a nice day” and updates the stock info (one coke less now).
  3. Token transaction: In case you have a coke, you can just pass it to your friend. For money or for free. In tokens reality, you have your token wallet which is supported by the same platform that issued the token. You can transfer your token using the wallet. And again, a virtual notary, powered by a smart contract, will make sure you do it according to the rules. Moreover, all the wallets activity is constantly recorded and being updated.
Tokens factory
Is all this free? Nope. Somebody needs to pay for the notary, vending machine technician and coke delivery. In the token world – the operation processing called “gas.” So, each time you ask to buy or sell tokens, there will be some “gas” spent and you will pay its fee.
Note: the fee is not static. It depends on a number of transactions awaiting. You can define the max cap you are willing to pay for your gas. If the token cost is, say, $10 and the gas fee is $20 is not a great deal, isn’t it? So, you can say that you pay no more than $2 for your gas, click “submit” and find something else to do meanwhile. The system will serve the highest gas bids first and eventually yours when your time will come. There is a chance, you will wait for a long time (if others are willing to pay more than you). But you always can rise the gas cap.

Types of tokens 

Let’s see the most common types of tokens.

Token – token (Utility tokens), the most popular type 

Remember amusements parks from the childhood? Roller coasters, carousels, hot dogs and cotton candy? At the entrance, you’ve got tokens to buy food and enter the attractions.
Cryptocurrency on the rides
So, let’s pretend that a company is an amusement park and with the tokens, you can buy different services just as you do with carousels and hot dogs.
Now, to make the analogy perfect, let’s say that you can buy lots of tokens before the park is officially opened, or when it’s just opened. If the park becomes popular, its tokens will be much more expensive. Like $10 for a hot dog. But a smart child who bought the tokens before the opening will still enjoy his meal for $1.
This is basically the idea behind issuing and buying tokens. But if in the amusement park you buy the tokens at the entrance, where do you get a cryptocurrency token?
The answer is ICO – Initial Coin Offering.

Token – stock (Equity tokens) 

In this case, ICO is completely equal to IPO. Usually, token-stocks are issued when a startup does not require a crypto-technology.
In this case, token holders will get dividend or fixed commission. They also will be able to take part is the company decisions. All this honor for supporting the project in the beginning of its life.

Token – credit 

This is a loan; a holder gives to a startup. It’s another way to rise money. For example, you invest X to get X + 10 percent.

Token – combo 

If you are not completely confused, you will be now: sometimes a token can belong to more than one type. For example, tokens Sia and Digix are both tokens and stocks. And Steemit has all the three types of tokens (Steem, Steem Dollars (SBD) and Steem Power (a denomination of VESTS).
Spider-Man thinking to buy ICO tokens

How do you trade tokens? 

This part is pretty similar to coins. You have to register on an exchange for buying and selling tokens.
The transaction conditions can be really complicated: the contract can include multiple rules like “you can sell it only before a specified date” or “after some date but only for a certain vendor.” So, when investing in tokens, you should read the “small letters” really thoroughly.

Altcoins With Lightning Network Support


Bitcoin has always been the world’s main and most valuable cryptocurrency, and that’s not likely to change any time soon. Still, many people believe that Bitcoin has been in a crisis for quite some time now. Indeed, lately there’s been a lot of complaints from users not only having to wait for several hours until their transaction is confirmed, but also paying exorbitant fees in the process.
The problem here is that Bitcoin’s blockchain is only capable of processing up to 7 transactions per second, which causes delays and increases fees. If Bitcoin is ever to become a widely-adopted payment system, that figure really needs to change.
A man with altcoins in a lab
There have been many potential solutions to this problem, but perhaps the one with the most potential is the Lightning Network. Essentially, the Lightning Network creates an extra layer on top of Bitcoin’s blockchain, enabling fast and cheap transactions which don’t have to be immediately broadcasted to the community.
In short, that extra layer is comprised of two-way user-generated channels enabling users to send money to each other as often as they need to, instantly, with minuscule fees. Of course, there is a lot more to it, so check out our dedicated guide to learn exactly what the Lightning Network offers to the community.
Spoiler: it’s a lot - the Lightning Network was originally designed to solve Bitcoin’s problems, but it seems that a multitude of altcoins have taken a liking to it as well. Some are planning to implement the entire network as it is, while others are working on their own, albeit very similar solutions.
Perhaps technologies like the Lightning Network are the next logical step in the development of cryptocurrencies. Here’s our round-up of various networks’ takes on this latest trend.

Bitcoin and Lightning Network 

This has been thoroughly discussed in our previous guide, but here’s what’s happening with the Bitcoin Lightning Network in a nutshell:
The network is still very much in its infancy and it isn’t fully live yet. However, its testnet, which is an alternative environment used for testing - not real world transactions - has been live since December 2017.
The beta-version of the network was launched on Bitcoin’s mainnet on March 15. At the time of writing, just over a month after the launch, the Lightning Network’s node count stands just below 2,000, which is already more than the number of nodes in Bitcoin Cash.
Superman with Bitcoin Lightning Network
This implementation is called Lightning Daemon (lnd) and it was developed by Lightning Labs. Around the time of the launch, the startup also announced completion of a seed finance round. They’ve raised $2.5 mln, with contributions coming from some of the biggest names in the cryptocurrency industry.
Lightning Labs are not the only startup out there working on the Lightning Network. There are also other implementations being developed by Blockstream, ACINQ and other members of the community.
So, the completely streamlined and user-friendly version of the Bitcoin Lightning Network is yet to be released, but real Bitcoins have been sent and received via all three major implementations of the network, which also proved that all three of them are interoperable.
Lightning specifications have also been published, which enabled developers to begin working on various applications and other implementations of the network. Most importantly, you can actually already download Lightning Network wallets, albeit nearly all of them are beta-versions.
Lightning network wallet
Here’s a list of some Bitcoin Lightning Network wallets that are already available for you to play with and explore the Lightning technology:
  • HTLC — a web wallet created by Alex Bosworth that enables you to start making payments immediately and without any configuration.
  • Lightning-app — a desktop wallet developed by Lightning Labs, available for Mac and windows.
  • Zap — a desktop wallet with a user-friendly interface, designed by Jack Mallers.
  • Eclair — a mobile wallet for Android devices designed by ACINQ.

Litecoin and Lightning Network 

Scalability is a pressing issue for most cryptocurrencies in the market and Litecoin - which on many occasions has been referred to as ‘the silver to Bitcoin’s gold’ - is no exception. Litecoin has always been one of Bitcoin’s direct rivals, attracting users with its $0.40 transaction fee besides everything else.
Obviously, once the Bitcoin Lightning Network goes mainstream, Litecoin’s transaction fees are going to turn from an advantage into a major disadvantage overnight. So, perhaps it’s no surprise that of all the altcoins toying around with an idea of Lightning Network, Litecoin is the closest in terms of progress.
In fact, Lightning Labs’ implementation of the Lightning Network which launched on March 15 went live on both Bitcoin’s and Litecoin’s blockchains.
Doctor Strange with Bitcoin and Litecoin
Moreover, back in November 2017 Lightning Labs announced that their initial test of a cross-blockchain atomic swap of tokens was a success. To put it simply, an atomic swap is a way of instantly exchanging one token for another between their respective blockchains, essentially bypassing cryptocurrency exchanges. Which blockchains was the initial testing done on? Bitcoin and Litecoin.
If everything goes well, the Litecoin Lightning Network is expected to be launched by the Q3 2018. Undoubtedly it will give Litecoin a major push towards mass-adoption. Charlie Lee, the founder of Litecoin, even went as far as to say that Bitcoin’s transactions will still cost users more than Litecoin’s, even with Lightning Network. We’ll just have to wait and see.

Ethereum and Raiden 

The Ethereum network is faring better than Bitcoin in terms of the amount of transactions per second it’s able to process. It’s maximum capacity stands at around 20 transactions per second, which is nearly three times more than that of Bitcoin.
However, by its nature, Ethereum’s blockchain is way busier than Bitcoin’s as it not only works as a payment system, but also enables decentralized applications and initial coin offerings (ICOs). The vast majority of ICOs take place on Ethereum, which brings sudden floods of traffic as token sales take place, slowing down the entire network.
So, it only seems natural that such Ethereum will require a scaling solution that is fine-tuned to its needs. Ethereum actually has several different solutions in the works, but one is particularly noteworthy: Raiden.
Ethereum-man with a tablet
The concept of Raiden is very similar to that of the Lightning Network: it provides an extra layer outside of the main blockchain where users can create two-way channels to conduct instant, nearly free and safe transactions.
One major difference between the two is that Raiden is ERC20 compatible, which means that every single token issued on Ethereum - and there are hundreds of them - will work with Raiden.
Currently there’s no concrete date set for the mainstream rollout. Raiden was launched on Ethereum’s testnet in September 2017, after which the team behind it held an ICO and raised around $50 mln for further development.
But, in December 2017 a lighter version of the protocol called µRaiden (pronounced “Micro Raiden”) was deployed on the Ethereum mainnet. Essentially, it does the same thing by facilitating instant, trustless - meaning you don’t have to trust or even know the other person - and free transactions.
The difference here is that the main Raiden protocol administers a network of two-way channels, while µRaiden allows someone to open a payment channel that is able to transfer tokens in one direction only. Those are extremely useful for micropayments, like paying for a cup of coffee.

ZCash and BOLT 

Lightning Network will make transactions on all-transparent blockchains like Bitcoin a little bit more private, as all the micropayments made via its two-way channels don’t need to be broadcasted to the entire network. Still, the channel’s opening and closure will leave records of both participating parties as well as the initial and final splits of funds.
ZCash is a cryptocurrency network aimed at providing its customers with enhanced privacy and anonymity, so in order to scale their blockchain they had to develop their own solution. ZCash’s proposed extra layer is called ‘BOLT’ and is fully inspired by the Lightning Network.
What BOLT will do differently from the Lightning Network is that it aims to make the transitions performed within a channel unlinkable. It will be able to do so by utilizing two classic cryptography techniques: commitments - which will hide the value of the payment, and signatures - which will allow users to sign for transactions without revealing what exactly is being signed.
ZCash in a restaurant
Ian Miers and Matthew Green, the two researches behind BOLT, claim that their creation will be able to work on top of any other cryptocurrency, provided it supports the required cryptography primitives. It will be able to work on top of Bitcoin right now, but with certain adjustments. Still, Miers said that it works a lot better on top of an anonymous cryptocurrency like ZCash.
Miers and Green are planning to release a prototype in the near future, but actually incorporating it into a cryptocurrency will take a more time.

Ripple and Lightning Network 

The thing with Ripple is, it doesn’t actually need an extra layer to scale, as it was designed to handle a lot of transactions in the first place. According to the project’s website, it already consistently handles 1,500 transactions per second and it can be scaled to match Visa’s throughput.
However, back in August 2017 Ripple along with Bitfury, a full-service blockchain technology company, released a code that integrated Lightning Network into Interledger. Interledger is Ripple’s protocol developed to enable transactions between different blockchains.
Evidently, Ripple isn’t interested in Lightning as a way of extending the network’s capability. Instead, the project adopted it to make use of it’s atomic swap technology and make another step towards compatibility of different cryptocurrencies.
Ripple as a frisbee
This is an extremely exciting development, as Interledger was already capable of fascinating transactions between not just public blockchains, but also private ones and, most importantly, traditional payment systems like PayPal.
According to Ripple’s CTO Stefan Thompson, the long term goal for the merger of those two technologies is to enable the crypto community to seamlessly trade between different cryptocurrencies as well as send funds to any given blockchain from PayPal, Alipay, bank accounts and vice versa.

Monero and Lightning Network 

Monero is another privacy-oriented cryptocurrency, so implementing the Lightning Network as it is probably not going to fully work for them. However, there are plans of adding a second layer to the network, and the team sees Lightning as their preferred option.
All the infrastructure - including multisignature wallets which were added to Monero in September 2017 - for the Lightning Network to work is already there. However, before it can be implemented, the team will need to make some key improvements to the extra-layer in order to retain as much privacy as possible.
Monero and Bitcoin playing chess
Still, it seems that Monero will mostly be focusing on the Lightning Network’s atomic swaps technology, not its scaling capabilities. Less than a month ago, one of the Monero subreddit moderators mentioned that the network has a dynamic block size, and they’ll scale on-chain ‘just sort of because’.
In the meantime, Riccardo Spagni, one of the project’s creators, has recently said that he is working with Litecoin in an effort to incorporate Lightning Network into Monero and make atomic swaps between the two blockchains possible.
Undoubtedly, this will lead to Monero users being able to swap their tokens for any other cryptocurrency utilizing the Lightning Network in the near future.

NEO and Trinity 

NEO is very similar to Ethereum in a sense that it provides a blockchain-as-a-service platform, where users can run decentralized applications, execute smart contracts and hold ICOs. So, in the same way, the platform needed a specialized off-chain scaling solution and in keeping with ‘The Matrix’ theme, it’s called Trinity.
Neo and Kung Fu Panda
Trinity is still in the works, and to be quite honest, there’s no immediate need for it to be released. As it is, NEO can already process about 1,000 transactions per second, which is significantly more than most other cryptocurrencies, but the team is clearly thinking ahead.
Trinity, Raiden and Lightning Network are extremely similar, if not identical in what they do: taking payments away from the main blockchain and into user-generated channels, which in Trinity’s case are called State Channels.
What’s different between the three solutions is the underlying technology, as they need to be applied to three drastically differently designed blockchains.

Stellar and Lightning Network 

Stellar is another network on this list that can already process around 1,000 transactions per second and, according the project’s founder Jed McCaleb it can easily scale to a lot more than that.
Still, just several days after Lightning Labs unveiled their beta of the Lightning Network, Stellar announced that they will be integrating it, becoming one of the first platforms to publicly announce integration.
Jed McCaleb, Stellar co-founder
Even though Stellar might not need to extend it’s capabilities just now, McCaleb outlines three major benefits to integrating the Lightning Network: scalability, privacy and interoperability. He also mentioned that even though Stellar can scale easily, Lightning will take it ‘much, much further’.
Moreover, Bitcoin Core contributor and the leading developer of Stellar’s Lightning Network stated that Lightning is the most important protocol happening in the cryptocurrency space right now and that any platform not preparing off-chain scalability solutions is going to “get left in the payment dust”.
