Bitcoin Is Worth Less Than the Cost to Mine It

The production-weighted cash cost to create one Bitcoin averaged around $4,060 globally. […] With Bitcoin itself currently trading below $3,600, that doesn’t look like such a good deal. However, there’s a big spread around the average. […] Low-cost Chinese miners are able to pay much less — the estimate is around $2,400 per Bitcoin — by leveraging direct power purchasing agreements with electricity generators such as aluminum smelters looking to sell excess power generation.

The problems of darknet markets have triggered an evolution in online black markets. […]

Instead of using websites on the darknet, merchants are now operating invite-only channels on widely available mobile messaging systems like Telegram. This allows the merchant to control the reach of their communication better and be less vulnerable to system take-downs. To further stabilize the connection between merchant and customer, repeat customers are given unique messaging contacts that are independent of shared channels and thus even less likely to be found and taken down. Channels are often operated by automated bots that allow customers to inquire about offers and initiate the purchase, often even allowing a fully bot-driven experience without human intervention on the merchant’s side. […]

The other major change is the use of “dead drops” instead of the postal system which has proven vulnerable to tracking and interception. Now, goods are hidden in publicly accessible places like parks and the location is given to the customer on purchase. The customer then goes to the location and picks up the goods. This means that delivery becomes asynchronous for the merchant, he can hide a lot of product in different locations for future, not yet known, purchases. For the client the time to delivery is significantly shorter than waiting for a letter or parcel shipped by traditional means - he has the product in his hands in a matter of hours instead of days. Furthermore this method does not require for the customer to give any personally identifiable information to the merchant, which in turn doesn’t have to safeguard it anymore. Less data means less risk for everyone.

identical twins […] bought home kits from AncestryDNA, MyHeritage, 23andMe, FamilyTreeDNA and Living DNA, and mailed samples of their DNA to each company for analysis. Despite having virtually identical DNA, the twins did not receive matching results from any of the companies. […]

An entire DNA sample is made up of about three billion parts, but companies that provide ancestry tests look at about 700,000 of those to spot genetic differences.

I was a camgirl for five years. My highest earning month was $50,000. […] The ceiling on cam income is very high — top-range models make around $200/hr, and the super-high end ones can make $1000+/hr. The average income is roughly $40/hr, based on around 200 girls I surveyed a few years ago. […]

Nearly every camgirl I’ve seen has used logitech webcams.

From 1936-1972, approximately 50,000 lobotomies were performed in the US. The majority of these occurred during the “lobotomy boom” which occurred in the late 1940s and early 1950s. Curiously, the lobotomy’s popularity coincided with a consensus within the medical community that it was ineffective. […]

Physician Walter Freeman performed approximately 10% of all US lobotomies during his medical career (El-Hai 2005). Although the procedure was widely used, it swiftly fell out of favor when the FDA approved the first antipsychotic drug in 1954. […]

In this paper, we propose the lobotomy’s popularity and longevity in the US was the result of the incentives generated by the institutional structure of mental health provision. Primarily, we note that funding for public mental hospitals and asylums were provided by state and federal governments on a very low per capita basis. This served to constrained revenues. Lobotomized patients were easier to manage (their brain damage often made them docile), and the procedure was comparatively cheaper than other treatment methods. These factors, in conjunction with little incentive to effectively treat patients provided by bureaucratic oversight, motivated physicians to perform cost and conflict minimizing treatment.


In contrast, physicians operating in private mental hospitals and asylums were funded by the patients, their caregivers, or through philanthropic donations. […] [L]obotomy was less used in private mental hospitals.

“Amazon is not too big to fail,” Bezos said, in a recording of the meeting that CNBC has heard. “In fact, I predict one day Amazon will fail. Amazon will go bankrupt. If you look at large companies, their lifespans tend to be 30-plus years, not a hundred-plus years.”

Brooklyn-based blockchain software technology startup and Ethereum development studio ConsenSys has acquired asteroid mining company Planetary Resources, Inc. through an asset-purchase agreement. […]

ConsenSys is a production studio that creates enterprises in a wide range of business areas based on the Etherium platform for cryptocurrency and other blockchain applications. It has spawned 50 ventures, or “spokes,” including an online poker site, a legal services site and a “transmedia universe integrated with blockchain technology” called Cellarius. […]

Planetary Resources was founded in its present form in 2012, with initial backing from billionaires including Larry Page, Eric Schmidt, Ross Perot Jr. and Charles Simonyi. Its original mission was to identify and mine near-Earth asteroids for valuable resources, ranging from water that could be converted into rocket fuel to platinum-group metals that could conceivably be sent back to Earth.

Over the course of six years, the venture raised tens of millions of dollars and explored other potential revenue streams, including space telescope manufacturing, space selfies and an Earth-observation constellation called Ceres. […] But an anticipated funding round failed to come together, leading to a wave of staff cutbacks.

In 2017, the United States imported approximately 10.14 million barrels per day (MMb/d) of petroleum from about 84 countries. Petroleum includes crude oil, hydrocarbon gas liquids, refined petroleum products such as gasoline and diesel fuel, and biofuels including ethanol and biodiesel. Crude oil accounted for about 79% of U.S. gross petroleum imports in 2017 and non-crude oil petroleum accounted for about 21% of gross petroleum imports.

In 2017, the United States exported about 6.38 MMb/d of petroleum to 186 countries, of which about 18% was crude oil and 82% was non-crude oil petroleum.

The resulting net imports (imports minus exports) of petroleum were about 3.77 MMb/d.

The top five source countries of U.S. petroleum imports in 2017 were Canada (40%), Saudi Arabia (9%), Mexico (7%), Venezuela (7%), and Iraq (6%).

The top five destination countries of U.S. petroleum exports in 2017 were Mexico (17%), Canada (14%), China (7%), Brazil (6%), Japan (5%).

Nauru is an island country in Micronesia, a subregion of Oceania, in the Central Pacific.

With 11,347 residents in a 21-square-kilometre (8.1 sq mi) area, Nauru is the third-smallest state by area in the world, behind only Vatican City and Monaco.

The Nauruan economy peaked in the mid-1970s to early-1980s, when the phosphate deposits that originate from the droppings of sea birds began to be depleted. At its peak, Nauru’s GDP per capita was estimated to be US$50,000, second only to Saudi Arabia.

In anticipation of the exhaustion of its phosphate deposits, substantial amounts of the income from phosphates were invested in trust funds aimed to help cushion the transition and provide for Nauru’s economic future. However, because of mismanagement, including some wasteful foreign investment activities, the government is now facing virtual bankruptcy.

The phosphate reserves on Nauru are now almost entirely depleted. Phosphate mining in the central plateau has left a barren terrain of jagged limestone pinnacles up to 15 metres (49 ft) high. Mining has stripped and devastated about 80 per cent of Nauru’s land area leaving it uninhabitable, and has also affected the surrounding exclusive economic zone; 40 per cent of marine life is estimated to have been killed by silt and phosphate runoff.

In the 1990s, Nauru became an illegal money laundering centre, a tax haven and offered passports to foreign nationals for a fee. During the 1990s, it was possible to establish a licensed bank in Nauru for only US$25,000 with no other requirements. Under pressure from FATF, Nauru introduced anti-avoidance legislation in 2003, after which foreign hot money left the country.

[W]hy are some societies more religious than others? One answer is religious coping: Individuals turn to religion to deal with unbearable and unpredictable life events. To investigate whether coping can explain global differences in religiosity, I combine a global dataset on individual-level religiosity with spatial data on natural disasters. Individuals become more religious if an earthquake recently hit close by. Even though the effect decreases after a while, data on children of immigrants reveal a persistent effect across generations.
