Another solution has been found for the implementation of my plan to transfer production to space and create an orbital city. The details are below.

Actual web is a gem technology

It is common knowledge that spiders are fine weavers.

The thread that spiders produce has unique characteristics fully adapted for hunting. It is durable for its thickness, sticky, elastic and perfectly forms a network without any knots or additional fasteners. Now, for example, Japanese scientists are experimenting with some species of spiders, using genetic engineering, in order to get the most durable natural fiber. Carbon nanotubes are interwoven into this fiber to create a completely new quality- this "rope" is almost impossible to break. The ratio of the cross-section of the filament to the force applied to the break has no analogs in the modern world. These developments have not yet been put to practical use which is necessary for mass production, but scientists, as they say, are on the home stretch.

The Deceptions of Space, or the Not-So-Great Combinators

Countdown starts now

Not only has the web itself prompted scientists new technical analogies with the arachnoid species- the spider, developing a thread, moves on a web, making circular and radial movements. The carriage of the inkjet printer, where the cartridge is installed, moves in the same way, but only within the limits of the size of the device. Currently, 3D printers are very static devices.

What if we make the printer move in space and create extended 3D structures? This would be a great solution for outer space!

Then there would be no need to transport parts from Earth and their installation by astronauts to outer space. Another important point is the absence of seams or other joints that affect the rigidity of the structure.

It is these considerations that prompted the developers of Tethers Unlimited to create an arachnoid-like robot-3D printer SpiderFab. It's amazing how much this robot look resembles a spider! It has four limbs, each of which is a separate printer (the developers are going to increase the number of "legs"), the inflated "abdomen" is a container with the material for printing. Also, the robot has an autonomous power plant with a solar array for constant recharging. The robot will be able to move in the process of printing and create frame structures in the image and likeness of natural cobwebs.

The introduction of such a robot will solve the global problem- the creation of objects in space with such dimensions that the present state of technological development is not yet capable of. As I wrote above, the expensive delivery of parts and elements from the Earth will no longer be necessary. Also, all the "delights" of space mining will be revealed, when the elements extracted on asteroids and planets will be used. Space materials researched will allow creating such composites for printing, which were not possible under terrestrial conditions. Such a printer will be able to print any complex object in orbit, from a part or a spare part to gigantic stations. This would lead to materials being in abundance!

And now imagine a whole fleet of cosmic "spiders" that weave in the high orbit of the Earth an openwork skeleton of a giant object, in the near future finding the outlines of a space city... And this is no longer a dream!

Nasdaq Ventures into Bitcoin Futures

The second largest stock exchange in the world, with a market cap of $10 trillion, is getting closer to launch Bitcoin futures during the first half of 2019
Nasdaq Ventures into Bitcoin Futures

The second largest stock exchange in the world, with a market cap of $10 trillion, is getting closer to launch Bitcoin futures during the first half of 2019.

Joseph Christinat, the vice-president of Nasdaq’s media team, spoke with UK media outlet Express, stating that

“Bitcoin Futures will be listed, and it should launch in the first half of next year – we’re just waiting for the go-ahead from the CFTC but there’s been enough work put into this to make that academic.”

He also added, “We’ve seen plenty of speculation and rumours about what we might be doing, but no one has thought to come to us and ask if we can confirm it, so, here you go – we’re doing this, and it’s happening.”

Chart Analysis - BTC/USD

Chart Analysis - BTC/USD

After attempting to break the $4,500 barrier, Bitcoin has resumed its bearish action, losing over 5% during the last 7 days and 2.50% in the last 24 hours. It is now capped by a bearish trend line and headed towards the support at $3,700.

Currently, the pair is trading very close to the key handle at $4,000, and the way it behaves here will determine the next short-to-medium term direction. A strong move above the level will probably break the trend line, and this will open the door for a recovery into $4,500, which will also create a more significant higher low, making way for further upside. On the other hand, a bounce lower from $4,000 will likely make $3,700 the next short-term destination.

Support zone: 3700

Resistance zone: bearish trend line (as diagonal resistance) and the upper Bollinger Band (as dynamic resistance); 4500 in the longer term

Most likely scenario: break of the bearish trend line and move into upper BB

Alternative scenario: choppy action with a bearish bias.

The Speculative Price of BTC and ETH is Down, But the Fundamentals of the Coins are Just Fine

Just looking at the price of Bitcoin can cause panic, but there are far better metrics for measuring the health of a cryptocurrency
The Speculative Price of BTC and ETH is Down, But the Fundamentals of the Coins are Just Fine

Between the CNBC headlines and the red graphs, as well as the fake picture of BTC miners being dumped, it has been a scary time for cryptocurrency enthusiasts. The fall in the BTC price from the $6,000-ish mark in November to now has caused may to worry about the health and prospects of the bigger cryptocurrencies.

However, the price is just one metric that determines just how well the market and certain coins are doing. Moreso, the price of the cryptocurrency is also the most speculative market metric on which to measure it upon.

There are many different things to consider before basing your sole assumption on the price of a cryptocurrency, and Chris Burniske, a partner at Placeholder and well known cryptocurrency voice, explains that the fundamentals of cryptocurrencies are still showing good signs.

Supply-siders and demand-siders

Burniske, in a post on Medium, explains how he views the health of a cryptocurrency by looking at its fundamentals, and this includes deciphering what is happening with the supply-siders and demand-siders.

“Supply-siders are the folks who provision the network’s service (currently, the most common form of supply-sider is a miner), and demand-siders are the ones who consume the service,” he said.”

“In terms of demand-side and supply-side fundamentals, here are the simple ones I’ll showcase:

Bitcoin Demand-Side: Number of Daily Transactions (#), Estimated Daily Transaction Value (USD), Daily Unique Addresses Used (#). Ethereum Demand-Side: Number of Daily Transactions (#), Total Daily Gas Used. Bitcoin & Ethereum Supply-Side: Hash Rate.’”

He also goes on to determine the network value, rather than using its price per coin, and this is equated thusly: “Network Value” = “Price per Unit” x “Units of the Cryptoasset Outstanding,” according to Burniske.

Supply-siders and demand-siders

Burniske uses the above graphs to show that the while the network value of both ETH and BTC is slowly sliding, the the number of daily transactions is stable to ticking up.

From the peak, Bitcoin and Ethereum’s network values are down 81% and 93%, respectively, whereas daily number of transactions are only down 41% and 52%, respectively.

What he derives from this data is that the drawdown in the network value is actually far less than the drop in the price of both these coins.

On the supply side

Burniske goes on to look at data on the supply side, viewing the hash rates of both blockchains.

On the supply side

“Both Bitcoin and Ethereum’s hash rates are higher now than they were at both of their peaks. Yes, hash rate is (usually) a lagging indicator that follows price, and both Bitcoin’s and Ethereum’s hash rates are on negative slopes which require us to keep a close eye on them. But right now, this fundamental is outperforming price,” he explains

What Burniske is trying to show with this data and its analysis is that, while there is a down turn in the markets, the effects of such are not as strong as the percentage drop in price. The way in which the blockchains are functioning in terms of their supply-siders and demand-siders seems to indicate that the health of the blockchains are still much better than their price.

The speculative nature of cryptocurrencies has always seen it swing wildly, Bit price booms are followed by massive price drops. And although both these assets have lots over 80 percent of their value since their all time highs, that percentage loss is not accurately reflected if you consider their fundamental performance metrics.

Uber Co-founder is Launching a Cryptocurrency

The co-founder of Uber, Garrett Camp, will be launching a cryptocurrency without an ICO
Uber Co-founder is Launching a Cryptocurrency

 

Garrett Camp – the co-founder of the peer-to-peer ridesharing service Uber – will be launching a new cryptocurrency. Camp has banded together universities, scientists, and research institutes to help create a new cryptocurrency called the “Eco”. The goal of the Eco is to act as a currency that holds true to the original doctrine of digital currencies: a nearly instantaneous means of transacting that is not limited by borders or facilitated by a third party. Camp hopes that Eco will be used as a currency in tandem with bitcoin, gold, and fiat currencies.

However, the Eco Blockchain will have a few different features than you would expect a Blockchain-based currency to have. Eco’s Blockchain will be run by verified nodes rather than an anonymous system of computers that anyone can join to support the network. A verified node system rather than a completely decentralized system of nodes is a kind of middle ground between decentralization – like the Bitcoin network – and centralization – like the Federal Reserve System. By having a system of verified nodes, Eco sacrifices a higher level of security for coordinated governance and efficiency – a system that runs on verified nodes removes the threat of a 51% attack occurring on the network.

Another difference between Eco and most Blockchain-based currencies is the incentive that the Eco network offers for mining Eco. On Eco’s Blockchain, when a verified node confirms a new block, the reward is distributed to every node and user on the Eco network. Because the system is structured like this, miners are incentivized to do as little work as possible to mine the currency. Since the mining reward is shared with every node and user on the network, there is no advantage in using powerful computers that can confirm blocks at a faster rate. Eco will be more efficient than Blockchain-based currencies that reward a single miner who confirms a block because Miners will not be incentivized to use more computing power to mine Eco coins.

Camp is looking to partner with universities and research institutions that are ranked in the 5th percentile to run the first set of nodes. Individuals who run nodes will also be known as token generators in the Eco community. Unlike most Blockchain-based tokens, the Eco will not have an ICO. To launch the Eco project, Camp is creating a non-profit organization, The Eco Foundation, that Camp and a small number of partners affiliated with Expa – the four year old startup accelerator business that Camp founded – have invested $10 mln into.

Overall, there will be 1 trillion tokens generated over the course of several years. Camp plans for five hundred billion Eco to be distributed to the first one billion users. ⅕ of the original supply will be set aside for verified nodes, 1/10 to the Eco foundation – which pays operation expenses and funds research grants, 1/10 for advisors and active contributors, and the last tenth for strategic partners.

Camp believes that the Eco test-net could be running as earlier as six months from now.

Today’s Crypto World: What’s in It for Me?

What the heck is cryptocurrency really? Find out how it emerged and what the average Joe can do with it
Today’s Crypto World: What’s in It for Me?

Cryptocurrency has turned into a buzzword in 2017, but how much do you know about it? Learn the basics of crypto technology, its advantages, and spheres of application.

Although the encryption technology and cryptocurrencies appeared in 2013 or earlier, the world witnessed its meteoric rise in demand in 2017. This is when millions of people caught the crypto bug and started investing heavily in Bitcoin and tokens alike. But what do we know about this buzzword? In the US, only 20% of residents are aware of what cryptocurrency is. Only 10% out of these people can explain crypto’s nuts and bolts, and the number of people who actually invest, implement, develop crypto products is even lower.

If you’re also in the dark about cryptocurrency, it’s time to shed some light on this phenomenon. Let’s answer a few popular questions concerning this technology and find out how it can be beneficial to you personally.

What Is Cryptocurrency?

Compared to fiat currency that exists in both physical and virtual forms, cryptocurrency is a 100% digital financial asset. The lynchpin technology underlying it is encryption: a certain form of data coding that prevents it from exposure to third parties. One more crucial advantage of crypto is decentralization, i.e. storage of data on multiple nodes in the form of the Blockchain. Encryption and decentralization have made cryptocurrency invincible and failure-proof. It allows for anonymous transactions and makes crypto totally independent from governments and banks.

“Through decentralized cryptography, Bitcoin eliminates the need for banking intermediaries, significantly lowering transaction costs. This holds promise for liberating poverty-stricken economies around the globe by providing access to capital to one-third of humanity which is currently excluded from the financial world,” - Perianne Boring, Founder & President of the Chamber of Digital Commerce

How Is It Created?

In its essence, cryptocurrency is a virtual asset that has no real value. Typically, the company standing behind a crypto project puts out a certain number of tokens and sells them or gives users a chance to mine them.

During mining, people provide their computing power in order to perform complicated mathematical calculations and create data blocks (PCs, mine rigs, and cloud servers are used for that). As soon as one data block is created, miners get rewarded with crypto tokens, as they use their own facilities to execute all crypto transactions.

Crypto vs Fiat Currency: What’s The Difference?

While regular currency units are printed by governments and are 100% controlled by states and banks, cryptocurrency is a totally independent asset. What exactly makes crypto superior? The list is a mile long:

  • Absence of geographical restrictions: transactions are made worldwide.

  • 100% anonymity of transactions (though, some cryptocurrencies do not support this feature on purpose).

  • Crypto money is not controlled by centralized entities like governments, banks, etc.

  • The crypto market offers thousands of currencies, each with its own technical feature.

  • It makes investment easier than ever before.

Can I Personally Benefit From Cryptocurrency?

There are many examples of successful cryptocurrency investors: Roger Ver, ‎The Winklevoss Twins, ‎Erik Finman, Jeremy Gardner, and others. These entrepreneurs were both smart and lucky to invest in cryptocurrencies before they built the necessary momentum and their prices soared into space. You can start investing, too: the opportunities are out there! Be that as it may, it requires quite a bit of financial literacy, patience, intuition, and analytical skills. A hit-or-miss strategy here is likely to fail.

Some choose to invest in ICOs (a buy-into option known as the Initial Coin Offering). Startups emit tokens to raise funds, and if things go well, their proprietary cryptocurrency grows in price. Nevertheless, statistics show that 90% of all ICOs are actually drowning ventures, as their tokens never make it to the exchange market. This means that you should think twice before spending your hard earned cash on questionable projects, that is, you should definitely do your homework before leaping ahead.

The crypto perks extend well beyond investment. Mining used to be arguably the quickest and easiest way to earn cryptocurrency, but now it requires a lot of computing power and, consequently, electricity and equipment costs.

When you do become a proud owner of cryptocurrency though, you can:

  • Perform anonymous transactions across the globe for a minimal fee.

  • Make purchases with Bitcoins and a handful of other altcoins.

  • Cash out your crypto coins when the time is right.

The Bottom Line

Even if you want to stay away from cryptocurrency right now, having some basic information about it most certainly wouldn't hurt. Sooner or later, we’re bound to witness the true rise of the crypto commodity all over the world, the world in which crypto knowledge will hold the true power. Hold tight!

Ripple Mining Explained: Why It Can’t be Done

📚 Wikicoin
Being a top cryptocurrency, Ripple appeals to both corporate and individual investors, but can it really be mined?
Ripple Mining Explained: Why It Can’t be Done

The cryptocurrency market is thriving, and all major players are doing everything possible to get the piece of the market cap pie which was, by the way, worth $1 trillion at the beginning of 2018. Thanks to technological advances, Ripple (XRP) has made its way to the top: it’s the 3rd most popular crypto asset in the world. If this currency has piqued your enthusiasm, it’s time to find out how to mine XRP (spoiler alert: it’s impossible).

Why mining is so attractive

As the prices of cryptocurrencies started going up, investors started trying every trick in their repertoire to obtain the coins. Mining is one of the most widely used methods: you can add to your crypto riches by using the computing power of your hardware. No strenuous efforts are required, you just need to install the mining rig, provide electricity and cooling on a 24/7 basis, and wait. The computational power is used to perform certain sophisticated mathematical calculations and generate the blocks for crypto transactions to be executed.

Why mining is so attractive

However, the difficulty of these computations is growing at an exponential rate, so Bitcoin and Ethereum mining requires juggernaut servers and mining rigs for outperforming rivals. For this very reason, crypto enthusiasts switch their attention to different altcoins. Wonder if there’s a chance to mine XRP? It’s time to set the record straight.

Is mining Ripple possible?

So, can you mine Ripple to join the rows of crypto owners? That may sound disappointing, but there’s simply no way.

Why has the team behind XRP decided to sidestep Ripple mining?

  1. Ripple was primarily created as a digital currency for banks rather than individual users. Despite the fact that many banks can use their own Blockchain technologies and avoid using this cryptocurrency, having a universally acceptable cryptocurrency is easier. That’s why over 100 banks are already adopting this asset. Ripple is making its way to the top, thanks to financial institutions mostly.

  2. While digital cryptocurrencies are decentralized, Ripple takes a slightly different approach. Although third-party validating nodes authorize transactions, Ripple Labs is still in charge of operations.

  3. The main reason why you cannot mine Ripple is the fact there’s nothing to mine: the entire stock of coins has already been released.

The company behind Ripple explained why it doesn’t need Ripple coin mining. According to Ripple Labs, the amount of emitted coins is enough to sustain normal circulation of assets within the following five years, and the existing track of investments and transactions proves that the current amount of XRP is enough to sustain an optimal functioning of the infrastructure.

How High Ripple (XRP) Price Can Go — XRP Price Prediction for the End of 2018

How does it work?

As we’ve already mentioned, mineable cryptocurrency becomes available to those who show Proof of Work to receive block rewards. As the difficulty of calculations grows and we approach the maximum available supply, the expansion of the coin slows down.

The main benefit of this system is that the market can partially control the amount of effort put into block generation. When prices are low, the cost of mining can be higher than the value of the obtained coins, which leads to less mining activity. The rise in prices triggers a higher mining activity, and that’s what we witnessed a year ago.

How does it work?

When it comes to Ripple, there’s no need to leverage XRP mining: its market cap belongs to banks rather than individual users. The supply of 100 bln XRP has already been emitted. The founders have kept 20 bln of Ripple to themselves, and the remaining 80 bln XRP was contributed to the company. In December 2017, Ripple Labs distributed 38.7 bln XRP and put 55 bln XRP in an escrow account.

The escrow system is pretty simple. One of 55 escrow contracts expires within a month. Every contract covers 1 bln XRP and becomes available to Ripple Labs for sale to banks or reward to market contributors. If one month’s Ripple supply isn’t used, it goes back into the escrow. With this approach, the circulating supply of Ripple will double within the next 3.5 years. According to Ripple labs, during the last 1.5 years, 300 mln XRP were used every month. With such rates, the entire Ripple supply will go through the escrow in 14–18 years.

Ripple’s development will depend on how fast the financial institutions adopt this cryptocurrency and use it as a medium of exchange. Individual users and payments made through Ripple Labs don’t play as much role here.

So, I can never be a Ripple miner?

No, but you still have the opportunity to be a proud XRP owner. There’s only one way of doing it: purchase the coins on trading platforms. Instead of searching for a Ripple coin mining pool, find reliable cryptocurrency exchange websites and buy XRP for fiat or other cryptocurrencies.

Having some XRP in your portfolio is always a good idea because:

  • It’s one of the most reliable crypto assets with a high profitability potential.

  • Ripple is in demand: it’s easy to sell it whenever you want.

  • In the nearest future, it will be possible to make international transactions with minimal fees. From an individual user’s standpoint, Ripple is a nice alternative to Western Union and services alike.

So, I can never be a Ripple miner?

There’s no such thing as mining the XRP coin!

Whenever you see headlines and ads like “Ripple mining software,” “Ripple mining hardware,” or “I will show you how to mine Ripple on PC,” keep in mind that this is a trap. There are no Ripple mining pools, no cloud Ripple XRP mining, and no machines doing that.

If you see a cloud mining website that offers XRP mining, there’s a 99.9% chance it’s a scam.

Bottom line

So, how to mine Ripple? There’s NO way of doing it. Since the entire XRP supply was emitted right in the beginning, this is one of few semi-decentralized cryptocurrencies that doesn’t have such feature. However, there’s still a chance to own the coins: they can be bought on cryptocurrency exchange platforms. Ripple is widely present in the vast majority of leading crypto exchange websites, so it’s easily available.

P.S. If you’re a mining geek and accept only this way of obtaining coins, there’s always an alternative. Although you cannot mine Ripple, there’s a myriad of mineable altcoins, and they can all be easily exchanged for Ripple. And if you monitor the market closely, you may be lucky to profit from a favorable exchange rate.
