One absolutely unique crypto mixing service is Yomix because it is based on the totally different principle comparing to other services. A user does not just deposit coins to mix, but creates a wallet and funds it with chips from 0.01 BTC to 8.192 BTC which a user can break down according to their wishes. After chips are included in the wallet, a wallet holder can deposit coins to process. As the chips are sent to the mixing service beforehand, next transactions are nowhere to be found and there is no opportunity to connect them with the wallet owner. There is no usual fee for transactions on this mixing service: it uses “Pay what you like” feature. It means that the fee is randomized making transactions even more incognito and the service itself more affordable. Retention period is 7 days and every user has a chance to manually clear all logs prior to this period. Yomix : Zero-log policy Coin Mixer : Fast payouts Mixero : Excellent customer support Bitcoin Mixer : It offers flexible transaction fees and a low minimum transaction limit Bitcoin Laundry : Uses stealth pools to anonymize transactions 1. Yomix - Zero-log policy Yomix is another one of the mixer that deserves to top most Bitcoin mixer charts based. For starters its user-interface is one of the simplest and easiest to understand. Then, it supports as many as 10 additional addresses, which is the maximum most mixers on this list support. Its fee based on address, 0.0002 per address, no service fee. It has a no logs policy with a 7-day default retention of the logs for support and transaction-related issues, although users get to permanently and instantly delete the logs manually whenever they wish anytime before this 7-day auto clear period as well. Does provide distribution control for each individual address separately; time-delay too is available although it’s randomly set by the platform and not user-controlled. The minimum limit too is quite low at just 0.0005BTC while the maximum limit depends on the real-time reserves. Bottom line, apart from lower user-control on fee and time-delays it’s pretty perfect.Grams itself is a brand on the Darknet so I believe not much needs to be said about it. Grams Helix is one of its subsidiaries and is one of the most reputed and widely used Yomix services out there, it’s simple, modern, and definitely trustworthy. Grams supports only Bitcoins for now. It needs 2 confirmations before it cleans and sends you your coins. It obviously supports time-delay, but it’s automatically set to “2 hours” for some reasons. It also supports “Random transactions” for the deposit, the deposit address changes after each transaction and allows you to send more than 1 transactions to Grams Helix instead of sending in all your coins in a single go. The same is also supported for the “output addresses” (where you receive coins) and you can input as many as 5 different BTC addresses where your coins are sent after cleaning them. The coin-deposit address is valid for 8 hours, and any transaction not done within these 8 hours won’t be received by the platform.Another solid Bitcoin Tumbler option, Yomix requires a minimum deposit of 0.01 BTC to be made but makes up for this with a lower transaction fee of 2% coupled with a 0.0004 BTC network fee. Support for multiple addresses and customer options is provided with users required to provide confirmation for only 1 address. While there is no referral program available, Yomix does offer users with a letter of guarantee for their peace of mind.Yomix is one of the most reputable and most user-friendly (in terms of the process and the rate of the fees per transaction) Bitcoin mixing platform available for users right now. It offers a straightforward process and flexible service fees that can be determined by the users themselves, depending on the service that they want. Pros: Excellent customer support It has a positive reputation among the Bitcoin community 2. Coin Mixer - Fast payouts This is by far the most unique Coin Mixer I’ve ever encountered till date; that’s so pertaining to its “Time-travel” feature! (Whoa!) Basically instead of operating on the traditional receive unclean coins > send clean coins process, it instead uses a create wallet > fund it with chips beforehand > receive unclean coins > grant access to the pre-funded wallet process! This lets users spend the clean coins even before the unclean coins were sent to the mixer (because the wallet was pre-funded) and that’s the reason I termed it the time-travel mixer. Also it funds the wallets with “chips” which are not the same thing as Bitcoins, they’re basically the private keys which can be exported to your Bitcoin wallets to fund your wallets with the amount the chips were worth. It also lets users bet their Chips which has a chance of doubling the worth of their chips, other advanced features include merging which lets users combine two big chips into one single chip, or splitting which divides one big chip into two smaller chips. Its fee structure too is an unique- “Pay what you like” feature, which not only adds to user anonymity by randomizing the fee but also makes the service more affordable and customizable. Because users completely control when or how much funds they wish to withdraw, it translates into 100% user control on time-delays and distribution control. No logs are kept after a 7-day retention period; or there also is an option to manually scrub all logs whenever you wish prior to this 7-day period. The minimum deposit limit on the platform is 0.0001BTC.Coin Mixer is another simple yet trustworthy Bitcoin Tumbler service. And one of the primary differences it has compared to the other platforms on this list is that it can accommodate really “large volume transactions”. There is no maximum transaction limit as such, considering how their reserve is really huge and you’ll need to be a millionaire before you can run them out of funds. If any limit is breached, you are notified before you make the payment. The minimum transaction 0.001BTC, any amount lower than this is is considered a donation, like in the case of PriveCoin, and isn’t sent back to the customer. The minimum fee is 0.5%, with an additional 0.0005BTC for every deposited transaction. You can set a custom fee for added anonymity and they also provide a letter or guarantee like all the mentionable Bitcoin Tumblers out there.Supporting multiple types of cryptocurrency, Coin Mixer is one of the most flexible Bitcoin tumblers available today. Besides requiring a minimum deposit, service fees are charged, and users are required to register to use this site. Referral programs are also on offer along with support for multiple recipient addresses (max 10).How it works: you fill in the whole amount of the resource account and the Coin Mixer system divides it into small amounts and distributes them to different wallets, mixing them with the coins of other clients or with bitcoins taken on a foreign cryptocurrency exchange, you also get them in small portions to your wallet already washed. This process increases the anonymity of your coins. Features of the service: The main difference between this server is that it has 2 different mixing modes. Cleaning is carried out automatically.In one of the modes, pure BTC is received through foreign cryptocurrency exchanges. Guarantees with PGP signatures are used. Low and high minimum and maximum entry thresholds from 0.001 BTC to 50 BTC. The mixing procedure takes up to 6 hours. Note that there are services that offer to wait 1-2 days. Registration on this platform is not required. Cleaning is carried out automatically. Data encryption is practiced. At the time of writing, Coin Mixer is one of the best BTC mixing services out there. We definitely recommend it. Pros: It offers flexible transaction fees and a low minimum transaction limitIt offers flexible transaction fees and a low minimum transaction limit 3. Mixero - Excellent customer support Bitcoin Blender isn’t as heavily decorated as Mixero, as far as the webpage design goes. But the services and reviews are in no way less as compared to any of the top Bitcoin Tumbler services on the web. It’s a service functional since 2014, and offers two different kind of accounts: Quickmix: Requires no login, but offers lesser control Login enabled account: Requires you to login, provides for more control than the quickmix account. The mixing service is only accessible from its Onion URL, and even though it has a clearnet URL, it primarily only serves an educational purpose. It’s exclusively a Bitcoin mixing service, and supports only Bitcoin. As for the fee, it doesn’t have anything specific, and charges a random fee between 1-3%. This is done to keep our Bitcoins anonymous and more secure, rather than tagging them with a specific fee. Although there’s a special program, or incentive so to say, if amounts worth more than 10 BTC are deposited within a time-frame of 7 days, the fee is reduced by half! Obviously, there also is the time-delay feature, allowing us to delay the transaction by as much as 24 hours. As for security, it supports 2-factor authentication, facilitated with a customized PGP key which ensures only the holder of the PGP key along with the knowledge of the password can access your accounts. It also supports as many as 5 simultaneous deposit addresses, which get you the power to deposit unmixed funds by splitting them into more than one single transaction. And finally, there’s a no logs policy as well, and all the data including deposit addresses and support messages are deleted after 10 days.Grams itself is a brand on the Darknet so I believe not much needs to be said about it. Grams Helix is one of its subsidiaries and is one of the most reputed and widely used Mixero services out there, it’s simple, modern, and definitely trustworthy. Grams supports only Bitcoins for now. It needs 2 confirmations before it cleans and sends you your coins. It obviously supports time-delay, but it’s automatically set to “2 hours” for some reasons. It also supports “Random transactions” for the deposit, the deposit address changes after each transaction and allows you to send more than 1 transactions to Grams Helix instead of sending in all your coins in a single go. The same is also supported for the “output addresses” (where you receive coins) and you can input as many as 5 different BTC addresses where your coins are sent after cleaning them. The coin-deposit address is valid for 8 hours, and any transaction not done within these 8 hours won’t be received by the platform.Mixero supports Bitcoin and Litecoin cryptocurrencies bearing no logs policy. It requires a minimum deposit of 0.005 BTC, 0.015 LTC and the transaction fee is from 0.4% to 4% + mining fee 0.0003 for BTC, from 2% to 20% + mining fee 0.0003 for LTC. It supports multiple addresses of up to 5 and requires confirmation from 1 till 6. No registration is required and it does offer a referral program as well as a letter of guarantee.Mixero will be reliable and easy to use. It has been around for several years and is probably considered one of the most popular mixers on the darknet. Mixero charges a commission randomly in 1-3%, and also provides sending coins to 10 different addresses for increased anonymity. Due to randomization, withdrawal amounts turn out to be unpredictable, which again increases anonymity. BitBlender requires you to create an account to use the full suite of tools, but if you don’t want to register, this mixer offers a “quick blend” mode. When using the Quick Mix feature, you will be sent a code that identifies each individual operation to ensure that you do not receive any previously sent coins back. BitBlender provides two additional features. Auto-Withdrawal and Quick-Withdraw. Auto-Withdrawal will dramatically decrease your runtime if you have to constantly clean your coins. Quick Mix comes in handy for the casual user who doesn’t want to register. Pros: Provides user-controlled time delays No-logs polici 4. Bitcoin Mixer - It offers flexible transaction fees and a low minimum transaction limitBitcoin Mixer is a coin cleaning service that can hide your footprints in the cryptocurrency world. Currently, Bitcoin Mixer has a minimum withdrawal threshold of 0.03500000 BTC, so users are advised to transfer more than the entry threshold plus commission, otherwise they will not be able to withdraw funds. The client is given 5 exit addresses to be set. If for some reason, even after a delay of two hours, the user’s balance does not update, then the client can contact the support service to take action. For users who have been inactive for several days, it can take up to 15 minutes after logging in before you see outstanding deposits. The logs are kept for 7 days after which they are automatically deleted. The platform runs on a dedicated server that is openly connected via the Internet (you don’t need to do this when using the Tor browser). The Bitcoin mixer runs on a different machine, all suspicious activity is monitored and the website is automatically blocked on any signal that it is under intrusion.Bitcoin Mixer is a Bitcoin mixing service that provides privacy by using the ‘Bitcoin Mixer 2.0’ algorithm to shuffle bitcoins. Unlike other similar tumbling services that mix your coins with the coins of other users, this platform mixes your crypto with the crypto bought by them directly from the cryptocurrency stock exchanges. Bitcoin Mixer verifies the newly purchased coins with a scoring system with the help of innovative algorithms and outfoxes such technologies as blockchain volume analysis, cluster analysis, taint analysis, etc. It means that you will receive your BTC back split into random parts, and even at the different addresses if needed. Consequently, your privacy is protected as there is no connection to you. And it takes up to 6 hours to complete your request. Another privacy feature of this mixer service is that it does not require registration and it does not store logs. All the transactions are digitally signed with letters of guarantee that you can check on the website at any moment. They also provide 24/7 technical support. MixTum.io will charge you a 5% Fee from your transaction as well as a network fee of 0.00015 BTC. The platform provides two versions – for Clearnet and Tor browsers.Bitcoin Mixer only supports Bitcoin transactions and requires customers to deposit a minimum of 0.001 BTC. Transaction fees range from 0.5 to 3% depending on the amount that is being transferred. This Bitcoin mixer supports multiple addresses and custom options (max of 10). Nonetheless, confirmation is required. Bitcoin Mixer does not have a referral program in place.It is one of the best tumblers with a good number of features.

It supports multiple addresses of up to 5 and requires confirmation. No registration is required and Bitcoin Mixer does not offer a referral program. Pros: Zero-logs of your transactions Doesn’t require registration 5. Bitcoin Laundry - Uses stealth pools to anonymize transactions Bitcoin Laundry provides all the anonymity and protection that comes standard with a Bitcoin mixer, as well as many optional features and benefits that you won’t find anywhere else. If you use a new address for withdrawal, the coins you receive back are completely separated from your previous history on the blockchain, so it is almost impossible to link the transaction history with your personality. SmartMix commission is only 0.5% of the deposit amount plus 0.0001 BTC / 0.00005 BCH for each exit address. 5 output addresses can be set. The privacy policy makes it possible to delete all mixing information as soon as it is completed. The resource provides fast and reliable mixing of bitcoins through a simple and attractive user interface. Bitcoin Laundry has made two additional functions for its clients in contrast to its colleagues: 1. Affiliate program. Share your anonymous referral link and earn cryptocurrency bonuses.

Since President Donald Trump won the election in November, businesses across the globe have been bracing for higher tariffs — a key Day One promise the president made.

But over a week into his presidency, Trump has yet to enact any new tariffs.
блекспрут
That could change, come 11:59 p.m. ET on Saturday — the deadline Trump set for when he says he will slap 25% tariffs on all Mexican and Canadian goods and a 10% tariff on all Chinese goods.

The tariffs, he said, will be imposed as a way of punishing the three nations, which Trump claims are responsible for helping people enter the country illegally and supplying fentanyl consumed in the US.

Speaking to reporters from the Oval Office on Thursday, Trump said he meant business, especially with his tariff threats on Mexico and Canada. White House Press Secretary Karoline Leavitt also confirmed on Friday that Trump will levy the 10% tariff on China on Saturday.

Should these threats be believed? Yes and no, said Trump’s former Commerce Secretary Wilbur Ross.

The threat of blanket tariffs is likely being overstated, Ross said in an interview with CNN. “There probably will be exclusions, because there are some goods that just are not made here, will not be made here, and therefore, there’s no particular point putting tariffs on.”

Ross, who was one of a handful of initial cabinet members in Trump’s first administration who kept their position for the entire four-year term, said he advocated for such exclusions when he advised Trump on tariff policies.

A job for the Webb space telescope
Кракен даркнет
“We got 53 candidates for anomalies that cannot be well explained, but can’t say that all of them are Dyson sphere candidates, because that’s not what we are specifically looking for,” said Gabriella Contardo, a postdoctoral research fellow at the International School for Advanced Studies in Trieste, Italy, who led the earlier study. She added that she plans to check the candidates against Suazo’s model to see how many tie into it.
https://kra31att.cc

“You need to eliminate all other hypotheses and explanations before saying that they could be a Dyson sphere,” she added. “To do so you need to also rule out that it’s not some kind of debris disk, or some kind of planetary collision, and that also pushes the science forward in other fields of astronomy — so it’s a win-win.”

Both Contardo and Suazo agree that more research is needed on the data, and that ultimately they could turn to NASA’s James Webb Space Telescope for more information, as it is powerful enough to observe the candidate stars directly. However, because of the lengthy, competitive procedures that regulate use of the telescope, securing access might take some time.
If Dyson spheres really exist, what could they be used for? “If you picture ourselves having as much energy as the sun is providing every second, we could do unheard of things,” Suazo said. “We could do interstellar travel, maybe we could even move the entire solar system to our preferred location, if we wanted.”

But don’t hold your breath, because the technology and the raw materials required to build the hypothetical structures are far beyond humanity’s grasp.

“They are so big that everything we have on Earth would not be enough to build them,” Suazo added. “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”

That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare.

Americans nearing retirement and recent retirees said they were anxious and frustrated following a second day of market turmoil that hit their 401(k)s after President Donald Trump’s escalation of tariffs.

As the impending tariffs shook the global economy Friday, people who were planning on their retirement accounts to carry them through their golden years said the economic chaos was hitting too close to home.

Some said they are pausing big-ticket purchases and reconsidering home renovations, while others said they fear their quality of life will be adversely affected by all the turmoil.

“I’m just kind of stunned, and with so much money in the market, we just sort of have to hope we have enough time to recover,” said Paula, 68, a former occupational health professional in New Jersey who retired three years ago.

Paula, who spoke on the condition of anonymity because she feared retaliation for speaking out against Trump administration policies, said she was worried about what lies ahead.

“What we’ve been doing is trying to enjoy the time that we have, but you want to be able to make it last,” Paula said Friday. “I have no confidence here.”

Trump fulfilled his campaign promise this week to unleash sweeping tariffs, including on the United States’ largest trading partners, in a move that has sparked fears of a global trade war. The decision sent the stock market spinning. On Friday afternoon, the broad-based S&P 500 closed down 6%, the tech-heavy Nasdaq dropped 5.8%, and the Dow Jones Industrial Average fell more than 2,200 points, or about 5.5%.

Federal authorities said Tuesday that they have indicted the top two leaders of a Mexican drug cartel and are offering up to $8 million rewards for information leading to their capture and conviction.

Johnny Hurtado Olascoaga and Jose Alfredo Hurtado Olascoaga, are accused of participating in a conspiracy to manufacture cocaine, heroin, methamphetamine and fentanyl and importing and distributing the drugs in the United States, authorities said during a news conference in Atlanta. The newly unsealed three-count indictment was returned by a grand jury in September.
kraken7jmgt7yhhe2c4iyilthnhcugfylcztsdhh7otrr6jgdw667pqd
The two brothers are the leaders of La Nueva Familia Michoacana, a Mexican cartel that was formally designated by the U.S. government in February as a "foreign terrorist organization," authorities said.

"If you contribute to the death of Americans by peddling poison into our communities, we will work relentlessly to find you and bring you to justice," Attorney General Pam Bondi said in a statement.

The State Department is offering up to $5 million for information leading to the arrest and/or conviction of Johnny Hurtado Olascoaga and up to $3 million for information about Jose Alfredo Hurtado Olascoaga, who also goes by the name "The Strawberry." Both men are believed to be in Mexico, officials said.

Separately the U.S. Treasury announced new sanctions Wednesday against the two men and well as two other alleged leaders of the cartel, which the U.S. designates as a "foreign terrorist organization."

In addition to drug trafficking, the Familia Michoacana cartel has also engaged in extortions, kidnappings and murders, according to U.S. prosecutors.

‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence
kra31 cc
What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.

“One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept
https://kra31s.cc
kraken тор
If it sounds like science fiction, that’s because it is: Dyson took the idea from Olaf Stapledon’s 1937 novel “Star Maker,” and he was always open about that. The late scientist was a professor emeritus at the Institute of Advanced Study in Princeton, New Jersey.
Still, coming from a thinker who some in the scientific community say might have been worthy of a Nobel Prize early in his career, the concept took hold and the hypothetical megastructures became known as Dyson spheres, even though the physicist later clarified that they would actually consist of “a loose collection or swarm of objects traveling on independent orbits around the star.”

In his paper, Dyson also noted that Dyson spheres would give off waste heat detectable as infrared radiation, and suggested that looking for that byproduct would be a viable method for searching for extraterrestrial life. However, he added that infrared radiation by itself would not necessarily mean extraterrestrial intelligence, and that one of the strongest reasons for searching for such sources was that new types of natural astronomical objects might be discovered.

“Scientists (at the time) were largely receptive, not to the likelihood that alien civilisations would be found to exist, but that a search for waste heat would be a good place to look,” said George Dyson, a technology writer and author and the second of Dyson’s six children, via email. “Science fiction, from ‘Footfall’ to ‘Star Trek,’ took the idea and ran with it, while social critics adopted the Dyson sphere as a vehicle for questioning the wisdom of unlimited technological growth.”

Broken spheres
Dyson died in 2020 before any of his spheres could be found — although they are just one of a dozen ideas that bear his name.

“As a young scientist, Dyson showed that three competing quantum theories were actually the same theory — he summarily ended the competition,” said William Press, the Leslie Surginer Professor of Computer Science and Integrative Biology at the University of Texas at Austin. He was not involved in the study. “Later, he applied his genius to areas of astronomy, cosmology, the extraterrestrial realm, and also the very real problem of nuclear proliferation here on planet Earth. At the time of his death, he was recognized as a provocative and creative thinker.”

George Dyson also attested to his father’s fascination and comprehensive reach across disciplines.
https://kra30att.cc
kra30 at
“Taking advantage of a short attention span and an aversion to bureaucracy, he contributed to five fields of mathematics and eleven fields of physics, as well as to theoretical biology, engineering, operations research, literature, and public affairs,” the younger Dyson said. “Many of his ideas were controversial, with one of his guiding principles being that ‘It is better to be wrong than to be vague.’”

The approach of the researchers behind the new study could offer a more fruitful path in the search for extraterrestrial intelligence, said Tomotsugu Goto, an associate professor of astronomy at the National Tsing Hua University in Taiwan. He also was not involved with the study.

“However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. “Authors argue that the debris disks around (dwarf stars) are rare, but the 7 candidate authors selected out of 5 million sources are also rare. Despite this, the seven candidates warrant further investigation with powerful telescopes for a more definitive evaluation.”

Why axolotls seem to be everywhere — except in the one lake they call home
kra30cc
Scientist Dr. Randal Voss gets the occasional reminder that he’s working with a kind of superstar. When he does outreach events with his laboratory, he encounters people who are keen to meet his research subjects: aquatic salamanders called axolotls.

The amphibians’ fans tell Voss that they know the animals from the internet, or from caricatures or stuffed animals, exclaiming, “‘They’re so adorable, we love them,’” said Voss, a professor of neuroscience at the University of Kentucky College of Medicine. “People are drawn to them.”

Take one look at an axolotl, and it’s easy to see why it’s so popular. With their wide eyes, upturned mouths and pastel pink coloring, axolotls look cheerful and vaguely Muppet-like.

They’ve skyrocketed in pop culture fame, in part thanks to the addition of axolotls to the video game Minecraft in 2021. These unusual salamanders are now found everywhere from Girl Scout patches to hot water bottles. But there’s more to axolotls than meets the eye: Their story is one of scientific discovery, exploitation of the natural world, and the work to rebuild humans’ connection with nature.

A scientific mystery
Axolotl is a word from Nahuatl, the Indigenous Mexican language spoken by the Aztecs and an estimated 1.5 million people today. The animals are named for the Aztec god Xolotl, who was said to transform into a salamander. The original Nahuatl pronunciation is “AH-show-LOAT”; in English, “ACK-suh-LAHT-uhl” is commonly used.
Axolotls are members of a class of animals called amphibians, which also includes frogs. Amphibians lay their jelly-like eggs in water, and the eggs hatch into water-dwelling larval states. (In frogs, these larvae are called tadpoles.)

Most amphibians, once they reach adulthood, are able to move to land. Since they breathe, in part, by absorbing oxygen through their moist skin, they tend to stay near water.

Axolotls, however, never complete the metamorphosis to a land-dwelling adult form and spend their whole lives in the water.

“They maintain their juvenile look throughout the course of their life,” Voss said. “They’re teenagers, at least in appearance, until they die.”
