$150 Billion: Total Cryptocurrency Market Cap Hits New All-Time High – CoinDesk

Posted: August 25, 2017 at 3:45 am

Via CoinMarketCap

The combined value of all publicly traded cryptocurrencies has set a new record, surpassing $150 billion for the first time today.

At press time, the value of ether, bitcoin and more than 800 other blockchain-based assets had reached a high of around $154 billion, according to CoinMarketCap.

Overall, the figure indicates that the cryptocurrency market continues to grow at a steady pace. At $154 billion, the market is up 13 percent over the last seven days, 67 percentover the last month and an astounding 1,240 percent year-over-year.

What might be most notable, however, is that the new high came during a trading session in which there were no individual all-time highs for major cryptocurrencies.

At $4,275 and $324, bitcoin and ether were edging up at press time,though still short of their highs above $4,500 and $400, respectively. Further, the new combined recordcame in spite of the fact there were no big gains in litecoin, monero or dash, some of the more popular alternative cryptocurrencies among traders.

The lone breakout, in fact, was Ripple's XRP token a cryptographic asset issued by a San Francisco startup seeking to build enterprise blockchain solutions. On the day's trading, XRP was up more than 50% to $0.28, a movement that built on impressive gains yesterday as well.

South Africa’s Central Bank: It’s ‘Too Risky’ to Launch a Cryptocurrency – CoinDesk

Posted: at 3:45 am

A senior official forSouth Africa's central bank has saidit's "too risky" for the institution to launch its own cryptocurrency.

Speaking during theStrate GIBS FinTech Innovation Conference 2017 on Monday, the deputy governor of the South African Reserve Bank, Francois Groepe, commented on developments in the fintech space, taking a particular focuson blockchain and distributed ledgers.

According to regional news sourceITWeb, Groepe suggested that the central bank has an open mind on the question of issuing its own digital currency. That said, he struck a cautious note about the short-term prospects of doing so.

"Virtual currencies have the potential of becoming widely adopted," he told attendees, going on to say:

"However, for the central bank to issue virtual currencies or cryptocurrencies in an open system will be too risky for us. This is something we really need to think about."

Groepe's comments come almost a year to the day after the South African Reserve Bank indicated that it would adopt an open perspective on the tech even leaving the door open to applications of its own.

"We are willing to consider the merits and risks of blockchain technology and other distributed ledgers," the bank's governor, Lesetja Kganyago, said at the time.

Other major financial players in the country, including its central securities depository, have also moved to investigate possible uses of blockchain.

No SegWit Bump? Bitcoin Price Shrugs Off Upgrade with Sideways Trading – CoinDesk

Posted: at 3:44 am

"SegWit is old news for the market."

So says crypto analyst Petar Zivkovski, and there's evidence to suggest traders largely agree. Despite just completing perhaps its most significant technical upgrade ever, the price of bitcoin is down just under 1% over the last 24 hours of trading.

To Zivkovski, this shows that bitcoin's upgrade, no matter how impactful, was for traders a classic "buy the rumor" event. He speculates much of the price activity in recent months was due to the upgrade prior to it being clear SegWit would be activated (thereby increasing and redefining network capacity), he notes bitcoin was trading below $2,000.

But before the network adopts the top-level payment networks and other next-generation features enabled by SegWit, Zivkovski expects a run of profit-taking.

Others are less certain here. Arthur Hayes, CEO of bitcoin derivatives exchange BitMEX, said that while the price will likely decline slightly in coming days, he expects it to "zoom higher" in the aftermath of the activation.

"My upside price target is $4,500 then $5,000," he told CoinDesk.

Elsewhere, comments hint that traders are just beginning to understand how cryptographic assets broadly respond to issues related to their technology. Charles Hayter, founder of exchange service CryptoCompare, for instance, chose to view it as the latest data point in an ongoing experiment on the matter.

Though he said it's likely to provide a "positive catalyst" long term, he hinted at an uncertain outlook in the coming days, remarking:

"With litecoin we saw a fall after the enaction of SegWit, but with bitcoin cash we saw a price rise on 8MB blocks being mined its half a dozen of one and half a dozen of the other for bitcoin."

Among analysts there was also a feeling that prices could be locked into the current range until November, when another technical change is anticipated for the network.

Given the controversy around the plan, and the possibility that it could result in the creation of a third major bitcoin asset, Hayes put forward this idea, arguing that while the price could creepabove $5,000, it's not likely to go much higher.

Elsewhere, developer and trader Jacob Eliosoff agreed that uncertainty is likely ahead as the market looks to price in those coming changes.

"I predict will be a huge mess and will do at least temporary damage to the price around the split itself," he said.

Bitcoin Price Analysis – Retesting all time highs – Brave New Coin

Posted: at 3:44 am

The Bitcoin network and price has been heavily influenced by Bitcoin Cash (BCash) and SegWit activation over the past few weeks. It is no coincidence that BCash was launched to directly compete in this manner.

The market has been struggling to continue to price in SegWit, a protocol improvement that lends itself to better network efficiency, and BCash, an attempt at direct competition to Bitcoin. This hypothesis can be evaluated by comparing various network metrics of both Bitcoin and BCash.

Prior to SegWit activation, BCash rose greatly in price. The increase was driven both from a technical basis of selling volume exhaustion, and likely a concerted effort to pump the price to increase mining profitability.

By doing so, miners who are coin agnostic moved their hash rate to BCash network for a better return. This activity may have also represented a specific mining pool or group of mining pools with an interest in the health of BCash.

In the meantime, transactions fees being paid to miners on the Bitcoin network are currently extremely high. BCash was created due to this very reason.

However, this may represent a ripple effect of network stabilization from the drop in hashrate creating a backlog in transactions. Although the backlog has been worse in the past with fees not as high, this was when Bitcoin was at a lower price.

The previous all time fee high was around the same time of a large temporary decrease in Bitcoin hash rate, before a difficulty adjustment occurred. This meant that average block confirmation times increased greatly, to above 16 minutes, and total possible transactions on the network decreased.

But hash rate has since rebounded, which should stabilize the network. Block size remains below the 1MB ceiling, which should be broken soon as SegWit is now active. This will in turn lower fees in the near term, making mining the chain less profitable.

The most basic analysis focuses on finding zones which are ranging versus zones with price action. Ranging zones can be thought of as zones of support or resistance, sometimes called orderblocks. There are buyers and sellers ready to jump into the market should it reach that zone again.

The recent increase occurred $200 above the previous orderblock, indicating the strength and momentum of the existing trend. Should a pullback occur, expect a stab into the ~$3150-$3470 orderblock.

Adding Fibonacci extensions, you can also estimate suggested support or resistance at the 1.618 fib, after measuring the extreme high and low of previous price action. Based on the two previous zones, there is fib resistance between ~$4800-$5000 on the next leg up. Expect the $5000 psychological barrier to hold, or a strong retrace from that level. Beyond the $5000 barrier, fib extensions suggest ~$5600-$5800 as the next pitstop.

Whenever the health of a trend is threatened, its important to fall back on what you know, so you are not driven by emotions, but rather, a tested and proven system. My favorite indicator for diagnosing the health of a trend is the Ichimoku Cloud.

The Cloud system is a constant, auto-drawn indicator which quickly offers an immense amount of valuable information on any time frame. The Cloud is best used at higher time frames as more data generally provides more accurate signals and less false positives.

The indicator uses moving averages and dynamic support and resistance to make projections of key zones, as well as capturing 80% of any given trend. As long as the price remains above the Cloud, sentiment remains bullish. Price in the Cloud indicates a neutral trend, and below the Cloud indicates a bearish trend.

When the Tenkan (T) is over the Kijun (K) sentiment is bullish. K over T would indicate bearish sentiment. When the Lagging Span (LS) is above the Cloud and above the price sentiment is bullish, below the Cloud and price would indicate bearish sentiment.

On the daily timeframe, despite the distance from price to the Kijun, which signals heavily overbought conditions, a Kijun bounce has yet to occur. There was a perfect Tenkan bounce, which traditionally signals strong continuation, ie, the trend is so strong, mean reversion cannot even occur. It is important to consider price as overbought despite an attempt at an ATH test. The Kijun remains a valid pullback target if/when that should occur.

On the four hour time frame, there was a bearish TK cross above cloud, a long exit signal (red arrow below). This assumes you were not already stopped out using other indicators, such as Heikin-Ashi candlesticks or Bill Williams fractals. Additionally, there was a short entry signal when price closed inside the cloud. I refer to this as an edge-to-edge trade. The target for these trades is always the opposite end of the cloud, which can be thought of as the next rung of support.

This target zone was essentially hit, and price bounced quickly. As with any support or target, its important to place entries or exits +/- a few dollars from the target for this exact reason. Currently, there is no indication to re-enter a long based on the four hour time frame, as there has not yet been a bullish TK cross (green arrow).

If getting out and back in a trade so quickly seems like a wasted opportunity or overtrading, consider that Cloud only aims to capture 80% of the trend. You can always buy, hold, and hope for the best. The Cloud helps mitigate risk by signaling reliable entry and exit signals.

There was also a 50/200EMA cross on the one hour time frame, another version of the bullish entry signal, at about the same candle as the Kumo Breakout. This can be considered confluence for a long entry.

Another trend following indicator is the Pitchfork, with an anchor drawn from the July 16th low. The median line (red) of the Pitchfork gives the expected mean of the trend. Price will continually attempt to return to this diagonal, around ~$4600.

Each diagonal of the Pitchfork can be thought of as a potential reversal zone or support/resistance line. The upper yellow diagonal zone being most overbought, or the top bounds of the trend, and lower yellow diagonal zone being most oversold, or the bottom bounds of the trend.

With SegWit approved the bitcoin network can now handle more transactions per block and therefore more transactions per day. For many, this is an important metric for understanding the value of the network as a whole. Technicals suggest at the very least a retest of all time highs, with $5000 being a likely new record very quickly.

Bitcoin, Ether extend gains, even as digital currencies take a regulatory hit – MarketWatch

Posted: at 3:44 am

Bitcoin rose modestly on Thursday as the most prominent digital currency recovers from recent sharp declines that briefly put it into correction territory.

Moves for the cyber monetary unit come as Securities and Exchange Commission temporarily suspended trading in the shares of First Bitcoin Capital Corp. BITCF, +4.68% because of concerns about the accuracy and adequacy of public information on the Canadian company.

Still, a single bitcoin BTCUSD, +2.62% rose 2.3% to $4,287.64, advancing for a third straight day, according to Coindesk.com data, and sending its total market value to about $70 billion, according to digital-currency research site Coinmarketcap.com.

Despite recent advances, the digital currency, is still about 5% below its record set on Aug. 17, though year to date, it is up more than 300%.

Bitcoin prices have been volatile, largely due to issues surrounding the need to increase transaction sizes in the blockchain network. Traditional bitcoin participants agreed on a new protocol known as Segregated Witness, or SegWit., which they believe solves bitcoins scaling issue.

The adoption of SegWit hasnt been smooth, with a minority of users rejecting it, leading to the split of bitcoin that created Bitcoin Cash.

On Thursday, the price of Bitcoin Cash fell 1.6% to 649.32, bringing its market cap to $10.7 billion.

Ether tokens, the chief rival to bitcoin, which runs on the Ethereum network, was little changed on Thursday at $323.74. Ether on Wednesday rose 0.4% to $325, its highest level since June 23. While it remains below an all-time intraday high above $400 hit on June 12, it has more than doubled from a recent intraday low hit in mid-July. For 2017, it is up about 4,000%, bringing its market cap to $30.6 billion.

The recent advances in bitcoin, along with the recovery in Ether, brought the total market capitalization of all cryprtocurrencies above $150 billion. The basket of cybercurrencies tracked by Coinmarketcap.com first broke above $100 billion in early June, meaning the space has risen by half in a little more than two months.

Meanwhile, shares of Firtst Bitcoin Capital Corp traded at $1.79 before its halt. The stock traded at $0.05 at the start of the year and gained more than 6,000% year to date.

First Bitcoin Capital Corp. is a Canadian corporation that invests in companies that mine bitcoin and operates exchanges and digital wallets, according to their website. The suspension was effective Thursday 9:30 Eastern Tim until noon Sept. 7.

In other news, A regulatory arm of Canada on Thursday signaled a warning about so-called initial coin offerings, or ICOs, which have spiked in popularity. The Canadian Securities Administrator, although acknowledging the benefits of raising funds by digital tokens, it said there are big risks.

However, they can also raise investor protection concerns, due to issues around volatility, transparency, valuation, custody and liquidity, as well as the use of unregulated cryptocurrency exchanges.Also, investors may be harmed by unethical practices or illegal schemes, and may not understand the properties of the investment products that they are purchasing, the CSA said, adding that it was monitoring developments in ICOs.

NASA sees space station cross the solar eclipse – CNET

Posted: at 3:44 am

The International Space Station transits the sun during the solar eclipse.

Look closely at this photo of the great North American solar eclipse. You'll notice the sun and the moon's rounded bite taken out of the side. Most of the dark specks are sunspots. But there's something else notable. A larger speck near the curve of the moon's shadow is the International Space Station.

The International Space Station Twitter account shared the photo on Monday with the message "It's the moon, sunspots AND the station in front of the sun. @NASA photographer captures station transiting sun during #Eclipse2017."

The ISS looks different from the sunspots. You can even make out the station's distinctive solar arrays.

The incredible photo took a combination of skill and luck to achieve. It stands with some of the great ISS transit photos of the past, including one from 2015 showing the station's path across the sun. This latest one is all the more spectacular with the backdrop of the eclipse.

International Space Station Astronauts to See Solar Eclipse …

Posted: at 3:44 am

Updated: Aug 21, 2017 11:24 AM ET

As millions of Americans look up to the sky to catch the total solar eclipse on Monday, or watch TIME's live broadcast , astronauts on the International Space Station are gearing up for multiple views of the phenomenon.

The crew on the Expedition 52 will not be in the eclipse's path of totality, but will see a partial view of the solar eclipse three times as they orbit the Earth from the station. The International Space Station will pass through moon's penumbra shadow, giving the crew a partial view each time. Since the station won't pass through the moon's umbra, the astronauts will not see the total eclipse, according to NASA . Each astronaut will have their cameras outfitted with special filters so they can photograph the solar eclipse aboard the station.

"We get three different looks at the eclipse," astronaut Randy Bresnik said during a NASA Facebook session on Friday. "Because we are going around the Earth every 90 minutes and about the time it takes the sun to cross the U.S., we'll get to see it three times."

NEXT: Watch the Whole Total Solar Eclipse in 4 Minutes

The International Space Station will first see the eclipse just before it begins in the U.S. The total solar eclipse is set to start in Lincoln Beach, Ore. around 9:05 a.m. PST. The crew should see a partial eclipse with about 38% of the sun obscured by the moon.

The second time, the International Space Station will see about 43.9% of the sun covered by the moon. Astronauts will also see the moon's shadow as it passes over parts of Illinois and Kentucky.

"As we come around the Earth again, this time on the second pass, we will actually cross over," Bresnik said. "We will be north of Lake Huron in Canada when we will be able to see the umbra, or the shadow of the moon, of the eclipse on the Earth. [Mission Control is] telling us around Tennessee-Kentucky, the western side of those states, that area, that we will be able to see it close to the horizon."

On its third orbit, the crew will see the eclipse as it passes over the East Coast. In the partial eclipse, 84% of the sun will be covered by the moon at its maximum point. The moon's shadow will not be visible.

Space station transits sun during eclipse – EarthSky

Posted: at 3:44 am

During the August 21, 2017 solar eclipse, the International Space Station (ISS) passed three times through the penumbral shadow of the moon on Earth. Astronauts aboard ISS captured images of the moons shadow on Earth, as did other earthly spacecraft. During the eclipse, people using the right equipment and located in the right place could catch the fleeting pass of ISS across the suns face. That pass was seen from a very thin ground track from California through Canada. Meanwhile, there was only one place where you could witness both a transit of the ISS across the partially eclipsed sun and the total solar eclipse later in the morning; it was at the intersection of this transit path with the moons shadow path in Wyoming. The video above from Destin Sandlin at the educational video series Smarter Every Day, and from professional photographer Trevor Mahmann, who earns his living in part via his Patreon page shows that ISS transit.

Its an amazing video and a tribute to our modern information world. Its only now through information sharing and combined knowledge that such things as videos of ISS transits across the suns face during eclipses have become possible!

Great job, guys, and awesome video!

Space Station astronauts catch sight of monster storm Hurricane Harvey – Mashable

Posted: at 3:43 am

Hurricane Harvey, which is forecast to become the strongest such storm to hit the U.S. in over a decade, is a gnarly sight from above.

Astronauts aboard the International Space Station captured the eye of Hurricane Harvey over Texas, where it's expected to make landfall Friday night or Saturday morning as a Category 3 or 4 storm.

Harvey is then forecast to stall out for days, dumping 2 to 3 FEET of rain along the Texas and Louisiana coastlines.

NASA astronaut Randy Bresnik posted two photos of the storm from space.

With the storm forecast to reach maximum sustained wind speeds of 125 mph, retired Canadian astronaut Chris Hadfield, who flew aboard the ISS, tweeted about seeing the massive storm brewing over "your family."

The NASA corps of astronauts are based in Houston, Texas, which is home to the Johnson Space Center.

These are powerful photos, but not as powerful as the Category 3 winds and rains forecast to come down fast on the Gulf Coast for many days in a row.

International Space Station Only Visible in Wyoming During Eclipse – Kgab

During the first phase of the eclipse, a visible object crossed in front of the Sun, it was not the moon, it was the International Space Station. It was uniquely visible from the state of Wyoming, according to Smarter Every Day.

Destin Sandlin, the host of the You Tube channel, Smarter Every Day, traveled all the way to Wyoming to see the eclipsebecause he and a buddy figured out that from there they could see something that could not be seen in any other state.

The entire eclipse was a three-hour event. The moment of totality only lasts 2.5 minutes. While totality is an amazing event, there is a lot to see during that long transit time.

Call it a Three Clips because you can see three objects at once. As the Moon crossed in front of the Sun, so did the International Space Station.

Amerter Every Day chose to set up in Crowheart, Wyoming as the best point to see the transit of the space station. They were gained special permission to view the event from aranch in the middle of an Indian reservation where not many people are allowed to visit.

Folks in Glendowere also able to see the transit of that space station as well, but Crowheart was considered the best place to witness the crossing, according to the math.

Anyone outside of Wyoming would not be able to see the station transit during the eclipse because of the time and angle of the eclipse in their corresponding area.

So chalk one up for our state, we had something extra to our eclipse that no one else got to see.
