Trading Volume On Top NFT Marketplace OpenSea Down 99% Since May

What was once a red-hot market fueled by FOMO during the crypto bull market of 2021 is now just a trickle, with trading volume on the most popular NFT marketplace, OpenSea, down 99% in just under four months. Fortune reports: On May 1, OpenSea processed a record $2.7 billion in NFT transactions, but on Sunday the marketplace recorded just $9.34 million worth, according to data compiled by DappRadar. The company recorded 24,020 users on Sunday, about a third fewer than when it hit its record transaction number in May. […] As trading volumes and crypto prices have fallen during a downturn that’s been dubbed “crypto winter,” the floor prices for the most popular NFT collections, which indicate the lowest price that an NFT in the collection is selling for, have also plummeted.

The floor price of the most popular NFT collection, Bored Ape Yacht Club, fell 53% to 72.4 Ether (about $110,000) as of Monday, from a high of 153.7 Ether on April 30, according to CoinGecko. Another popular NFT collection, CryptoPunks, is down 19% from its July peak. Yes, but: the report notes that “only 16% of U.S. adults had invested in crypto, nearly the same number who said they had invested last September.”

Twitter Is Becoming a Podcast App

Twitter has launched a test version of Twitter Spaces today that includes podcasts, “letting you listen to full shows through curated playlists based on your interests,” reports The Verge. From the report: The redesigned Spaces tab opens with Stations, topic-based playlists combining podcast episodes pulled from RSS with Twitter’s social audio events and recordings. It functions like a Pandora station but for spoken word and is pretty different from the a la carte listening podcast consumers are used to on Apple Podcasts or Spotify. Live and upcoming spaces are still in the tab, further down the page. The test will roll out to a random group of users across the world, initially only in English. The more users listen, the more tailored the audio Stations will become. But Twitter isn’t starting from square one — the company is relying on what it already knows about its users’ interests to curate the playlists. It’ll draw from the interests of people they follow, as well.

“What we’re really trying to capture here is as if it’s like another user recommending you something,” Twitter senior product manager Evan Jones, who focuses on audio, told Hot Pod. Podcast discovery is notoriously difficult, limited either to top 100 charts, hand-picked selections on apps, or — more often than not — word of mouth. No platform has managed to crack it, yet. It’s easy to imagine the promotional possibilities around being able to share and listen to podcasts in the same app, but it’s not quite there yet. The test does not yet have a clipping capability, and listening can only happen in the Spaces tab, not on the timeline. That being said, Spaces has a clipping feature that could be applied to podcasts at some point.

AMD Launches Zen 4 Ryzen 7000 CPUs

AMD unveiled its 5nm Ryzen 7000 lineup today, outlining the details of four new models that span from the 16-core $699 Ryzen 9 7950X flagship, which AMD claims is the fastest CPU in the world, to the six-core $299 Ryzen 5 7600X, the lowest bar of entry to the first family of Zen 4 processors. Tom’s Hardware reports: Ryzen 7000 marks the first 5nm x86 chips for desktop PCs, but AMD’s newest chips don’t come with higher core counts than the previous-gen models. However, frequencies stretch up to 5.7 GHz – an impressive 800 MHz improvement over the prior generation — paired with an up to 13% improvement in IPC from the new Zen 4 microarchitecture. That results in a 29% improvement in single-threaded performance over the prior-gen chips. That higher performance also extends out to threaded workloads, with AMD claiming up to 45% more performance in some threaded workloads. AMD says these new chips power huge generational gains over the prior-gen Ryzen 5000 models, with 29% faster gaming and 44% more performance in productivity apps. Going head-to-head with Intel’s chips, AMD claims the high-end 7950X is 11% faster overall in gaming than Intel’s fastest chip, the 12900K, and that even the low-end Ryzen 5 7600X beats the 12900K by 5% in gaming. It’s noteworthy that those claims come with a few caveats […].

The Ryzen 7000 processors come to market on September 27, and they’ll be joined by new DDR5 memory products that support new EXPO overclocking profiles. AMD’s partners will also offer a robust lineup of motherboards – the chips will snap into new Socket AM5 motherboards that AMD says it will support until 2025+. These motherboards support DDR5 memory and the PCIe 5.0 interface, bringing the Ryzen family up to the latest connectivity standards. The X670 Extreme and standard X670 chipsets arrive first in September, while the more value-oriented B650 options will come to market in October. That includes the newly announced B650E chipset that brings full PCIe 5.0 connectivity to budget motherboards, while the B650 chipset slots in as a lower-tier option. The Ryzen 7000 lineup also brings integrated RDNA 2 graphics to all of the processors in the stack, a first for the Ryzen family.

Are More Than Half of All Bitcoin Trades Fake?

Bitcoin represents 40% of the $1 trillion outstanding crypto assets, according to Forbes’ director of data and analytics. “An estimated 46 million adult Americans already own it according to New York Digital Investment Group…”

“But can you trust what your crypto exchange or e-brokerage reports about trading in the most important digital currency?”
One of the most common criticisms of bitcoin is pervasive wash trading (a form of fake volume) and poor surveillance across exchanges. The U.S. Commodity Futures Trading Commission defines wash trading as “entering into, or purporting to enter into, transactions to give the appearance that purchases and sales have been made, without incurring market risk or changing the trader’s market position.” The reason why some traders engage in wash trading is to inflate the trading volume of an asset to give the appearance of rising popularity. In some cases trading bots execute these wash trades in tokens, increasing volume, while at the same time insiders reinforce the activity with bullish remarks, driving up the price in what is effectively a pump and dump scheme. Wash trading also benefits exchanges because it allows them to appear to have more volume than they actually do, potentially encouraging more legitimate trading.

There is no universally accepted method of calculating bitcoin daily volume, even among the industry’s most reputable research firms. For instance, as of this writing, CoinMarketCap puts the latest 24-hour trading of bitcoin at $32 billion, CoinGecko at $27 billion, Nomics at $57 billion and Messari at $5 billion….

As part of Forbes research into the crypto ecosystem using 2021 data, we ranked the 60 best exchanges in March. More recently we conducted a deeper-dive into the bitcoin trading markets…. Our study evaluated 157 crypto exchanges across the world. Here are our main findings:

– More than half of all reported trading volume is likely to be fake or non-economic. Forbes estimates the global daily bitcoin volume for the industry was $128 billion on June 14. That is 51% less than the $262 billion one would get by taking the sum of self-reported volume from multiple sources….

– The biggest problem areas regarding fake volume are firms that tout big volume but operate with little or no regulatory oversight that would make their figures more credible, notably Binance, MEXC Global and Bybit. Altogether, the lesser regulated exchanges in our study account for approximately $89 billion of the true volume (they claim $217 billion).

Forbes adds that their report “builds on top of the important work done by other digital asset researchers such as Bitwise, which estimated in a March 2019 white paper that 95% of CoinMarketCap’s bitcoin trading volume was fake and/or non-economic.”

Their article includes some other interesting findings, including an observation that Tether “continues to be a dominant player in the crypto trading economy, especially when it comes to trades against bitcoin. Its current market capitalization is $68 billion, despite questions about its reserves.”

Are Plants ‘Intelligent’?

Long-time Slashdot reader Dr_Ish writes: It is not too common for the world of academic philosophy to be changed by a new discovery, or innovation. Perhaps the last time this happened in a major way can be traced back to Turing’s famous (1950) “Computational Machinery and Intelligence” paper “Mind,” where Turing proposed that computational systems could exhibit mind-like properties. However, it appears to be in the process of happening again.

In a series of recent papers and a book that was published last week, philosopher Prof. Paco Calvo from the University of Murcia, has made a compelling case that plants exhibit cognitive properties, such as memory, planning, intelligence and perhaps even numerical abilities… His book, Calvo, P. with Lawrence, N. “Planta Sapiens: The New Science of Plant Intelligence was published in the UK last week. It will appear in North America in March next year.

From the Guardian’s review of the book:
Calvo writes that intelligence is “not quite as special as we like to think”. He argues that it’s time to accept that other organisms, even drastically different ones, may be capable of it….

In the course of his book, Calvo describes many experiments that reveal plants’ remarkable range, including the way they communicate with others nearby using “chemical talk”, a language encoded in about 1,700 volatile organic compounds…. Other studies show that some plants retain a memory of where the sun will rise, in order to turn their leaves towards the first rays. They store this knowledge — an internal model of what the sun is going to do — for several days, even when kept in total darkness. The conclusion must be that they constantly collect information, processing and retaining it in order to “make predictions, learn, and even plan ahead”.

Soon Electric Vehicles Could Charge Faster Than Your iPhone

The Washington Post shares a little-acknowledged downside to electric cars: recharging takes “upward of 15 to 30 minutes.”

But scientists are already working on improvements:

In a report released this week, government researchers said they have found a way to charge electric car batteries up to 90 percent in just 10 minutes. The method is likely five years away from making its way into the market, scientists said, but would mark a fundamental shift. “The goal is to get very, very close to [times] you would see at the gas pump,” said Eric Dufek, a lead author of the study and scientist at the Idaho National Laboratory, a research center run by the Department of Energy….

At issue is the delicate balance of trying to charge an electric vehicle battery quicker, but not doing it so fast that a rapid charge does long-term damage to the battery or plays a role in causing them to explode. Charging electric batteries fast can cause damage, reducing the battery’s life span and performance, scientists said. “You’ve had batteries when you first got it, they were great, but after a couple years or a few hundred charge cycles, they don’t perform as well,” said Eric D. Wachsman, director of the Maryland Energy Innovation Institute, an energy research organization at the University of Maryland. To try to solve this, Dufek and his team used machine learning to figure out how batteries age when charging fast. Their algorithm was trained to analyze 20,000 to 30,000 data points which indicated how well the battery was charging and whether it was aging or degrading….

Wachsman said the new research is helpful for the field. “Not too fast, not too slow,” he said of Dufek’s charging approach. “It’s just right in that Goldilocks [zone].” But the bigger benefit, he said, would be if this method spurs car companies to make electric vehicles with smaller batteries, since they’d now have batteries that could be charged quicker and allow consumers to feel less worried about stopping periodically to get a quick recharge.

“Smaller batteries are cheaper cars,” he said.

DOJ in Early Stages of Drafting Possible Antitrust Suit Against Apple

Justice Department lawyers are in the early stages of drafting a potential antitrust complaint against Apple, Politico reported Friday, citing a person with direct knowledge of the matter — a sign that a long-running investigation may be nearing a decision point and a suit could be coming soon. From the report: Various groups of prosecutors inside DOJ are assembling the pieces for a potential lawsuit, the individual said, adding that the department’s antitrust division hopes to file suit by the end of the year. Still, the Justice Department has made no decisions whether or when to sue Apple, the world’s most valuable public company, cautioned that person and one other familiar with the probe — and it’s still possible no case will be filed. Both were granted anonymity to discuss a confidential investigation.

Psilocybin Therapy Sharply Reduces Excessive Drinking, Small Study Shows

A small study on the therapeutic effects of using psychedelics to treat alcohol use disorder found that just two doses of psilocybin magic mushrooms paired with psychotherapy led to an 83 percent decline in heavy drinking among the participants. Those given a placebo reduced their alcohol intake by 51 percent. From a report: By the end of the eight-month trial, nearly half of those who received psilocybin had stopped drinking entirely compared with about a quarter of those given the placebo, according to the researchers. The study, published Wednesday in JAMA Psychiatry, is the latest in a cascade of new research exploring the benefits of mind-altering compounds to treat a range of mental health problems, from depression, anxiety and post-traumatic stress disorder to the existential dread experienced by the terminally ill.

Although most psychedelics remain illegal under federal law, the Food and Drug Administration is weighing potential therapeutic uses for compounds like psilocybin, LSD and MDMA, the drug better known as Ecstasy. Dr. Michael Bogenschutz, director at NYU Langone Center for Psychedelic Medicine and the study’s lead investigator, said the findings offered hope for the nearly 15 million Americans who struggle with excessive drinking — roughly 5 percent of all adults. Excessive alcohol use kills an estimated 140,000 people each year.

Twilio Hackers Breached Over 130 Organizations During Months-Long Hacking Spree

The hackers that breached Twilio earlier this month also compromised more than 130 other organizations during their hacking spree that netted the credentials of close to 10,000 employees. TechCrunch: Twilio’s recent network intrusion allowed the hackers to access the data of 125 Twilio customers and companies — including end-to-end encrypted messaging app Signal — after tricking employees into handing over their corporate login credentials and two-factor codes from SMS phishing messages that purported to come from Twilio’s IT department. At the time, TechCrunch learned of phishing pages impersonating other companies, including a U.S. internet company, an IT outsourcing company and a customer service provider, but the scale of the campaign remained unclear.

Now, cybersecurity company Group-IB says the attack on Twilio was part of a wider campaign by the hacking group it’s calling “0ktapus,” a reference to how the hackers predominantly target organizations that use Okta as a single sign-on provider. Group-IB, which launched an investigation after one of its customers was targeted by a linked phishing attack, said in findings shared with TechCrunch that the vast majority of the targeted companies are headquartered in the U.S. or have U.S.-based staff. The attackers have stolen at least 9,931 user credentials since March, according to Group-IB’s findings, with more than half containing captured multi-factor authentication codes used to access a company’s network.
