Why isn’t the cost of mining Bitcoin more or less equal to the current price of Bitcoin?

A comment on Is inflation already at 15-30 percent if we hold delivery time constant?:

GPU scarcity is entirely due to the growth of digital currency mining and the corresponding increase in demand for the chips that do the mining most efficiently. A top-end GPU can recoup the list price from digital currency mining in two months.

Why is the return on investment quick/high for Bitcoin mining? If the price of Bitcoin goes up, shouldn’t there be an almost immediate flood of people into the mining business such that the cost of mining rises to just below the selling price of Bitcoin?

An explanation of the mining process:

Once miners have verified 1 MB (megabyte) worth of Bitcoin transactions, known as a “block,” those miners are eligible to be rewarded with a quantity of bitcoin (more about the bitcoin reward below as well). The 1 MB limit was set by Satoshi Nakamoto, and is a matter of controversy, as some miners believe the block size should be increased to accommodate more data, which would effectively mean that the bitcoin network could process and verify transactions more quickly.

Note that verifying 1 MB worth of transactions makes a coin miner eligible to earn bitcoin—not everyone who verifies transactions will get paid out.

To earn bitcoins, you need to meet two conditions. One is a matter of effort; one is a matter of luck.

2) You have to be the first miner to arrive at the right answer, or closest answer, to a numeric problem. This process is also known as proof of work.

If mining is lucrative, e.g., because mining costs $5,000 in carbon-spewing electricity while Bitcoin is selling for $40,000, shouldn’t so many new miners flood in that it would be less probable to “be the first miner to arrive at the right answer”? This would effectively raise the cost of mining and the process should continue until mining costs $39,000+.

I suspect that I’m missing something. “Why The Actual Cost Of Mining Bitcoin Can Leave It Vulnerable To A Deep Correction” (mid-2020):

In early 2020, researchers predicted the cost to mine Bitcoin will be at around $12,000 to $15,000 after the block reward halving in May. But, it is now much cheaper to mine BTC than the initial estimates. The low breakeven price to mine Bitcoin may leave it vulnerable to a correction.

Bitcoin has become more affordable to mine in recent weeks due to two main factors: difficulty adjustments and cheaper electricity in Sichuan, China due to the rainy season.

A low breakeven price of Bitcoin can raise the probability of a price pullback because miners have more incentive to sell BTC, which may increase selling pressure in the short-term.

“To be completely accurate: Given current difficulty, 0.04$/kWh and S9 running custom firmware bringing it down to 71W per TH efficiency. The cost to mine 1 BTC is 8206.64$. Meaning its still profitable,” one miner said.

Maybe my theory isn’t contradicted by this article. At the time it was written, the market price of Bitcoin was $9,626. But what is the cost of mining today relative to the market price of existing Bitcoin?

Why didn’t we ever get convenient neighborhood COVID-19 testing?

We spent $trillions purportedly fighting COVID-19. We said that testing was critical to this fight. There is empty retail space all over the U.S. (thanks partly to closures ordered by governors!). Why didn’t we ever get COVID testing that was actually convenient, fast, and simple?

Plainly it can be done. Here’s a storefront COVID-19 testing center near Times Square (June 12 photo):

Why weren’t there storefronts like this all over the U.S., starting around April 2020, the fees paid via the government money printing press?

Turn opprobrium into praise by identifying as LGBTQIA+?

Happy Pride Month again! Don’t forget that

Suppose that we hear about a financially secure 90-year-old white American having sex with a 31-year-old “Brown” immigrant? That’s an unequal power dynamic, right? And we would condemn this relationship, I’m sure. Former Miss Ukraine Oleksandra Nikolayenko isn’t especially brown, but she’s 40 years old and we don’t see a lot of media praise regarding her marriage to Phil Ruffin (86-year-old billionaire).

What if Mx. Nikolayenko said “I identify as a man” and Phil Ruffin said “I am gay”? Then we would have a love story suitable for publication… “‘I Found Love At 90 With A 31-Year-Old—After Finally Coming Out'” (Newsweek):

When he arrived, John was dressed in black with his black mask. We actually both had our masks on right up until the salad course was brought out. That was the first time we actually saw each other. We got talking and soon found that we had lots in common. Neither one of us smokes or drinks and neither of us uses foul language. We talked about shows that we liked and things we both enjoy around town; we both really like Asian food.

They had as much in common, in other words, as any two people selected at random from the Chinese population of 1.4 billion.

Young John is not prosperous:

He had three roommates so I didn’t visit him as it would have been less comfortable for us.

John is an immigrant:

John is originally from Mexico, where there are plenty of tarantulas, but he’s afraid of them.

Their friends are implicitly against polyamory:

Most of our friends now are also gay, and a number of them are in younger/older unions or marriages. It really doesn’t come up, nobody says anything about it because we’re two people who are happy together. That’s all our friends care about. Whenever it comes up in Facebook comments—and it does come up—I say that age is just a number. Of course it is an important number, but it is just a number.

Just a number? Let’s compare to Jeffrey Epstein, who died at age 66. It was disgusting when Epstein was 61 and there was a possibility of sex with a 19-year-old. See “‘UNCLE’ JEFF’S PLOT Jeffrey Epstein hatched plot to marry ex girlfriend’s 19-year-old daughter to give her £40m inheritance”:

JEFFREY Epstein told pals he wanted to marry the teen daughter of his beauty queen ex who called him “Uncle Jeff”, it has been claimed.

Celina Dubin, now aged 24, is the daughter of doctor and former Miss Sweden Eva Andersson Dubin – who the paedo dated in the 1980s.

Epstein reportedly enjoyed a close relationship with Eva and her husband Glenn Dubin – who she married in 1994 – a billionaire hedge-fund manager from New York City.

And in 2014, the sex offender, then aged 61, told friends that if he was ever to marry he would choose then-19-year-old Celina, reports Business Insider.

He said that he wanted the teenager to inherit his fortune and that marriage would help her avoid inheritance taxes, the report claims.

That same year, Epstein – who died in prison in August while facing child sex trafficking charges – named Celina as a beneficiary to his $500m fortune.

A source familiar with the millionaire’s estate told Business Insider that the young girl would have inherited $50m – however the paedo banker removed her from his will in 2015 for unknown reasons.

The Dubins reportedly spent holidays with Epstein even after his conviction in 2008 for having sex with a minor.

What if Celina Dubin had said “My pronouns are he/him/his” and Jeffrey Epstein had said “I am gay and find all three of the guys pictured below attractive, including Mr. Eva Dubin on the left and Mr. Celina Dubin on the right of the photo”? Now the romance between Mr. Epstein and Mr. Celina Dubin would be heartwarming instead of “gross”?

Good news for Californians who spent all of their money on marijuana

Both medical and recreational marijuana stores were open throughout California’s coronapanic shutdown. “Amid coronavirus pandemic, California gov classifies cannabis industry as ‘essential’ during state’s effective lockdown” (March 21, 2020):

Under a clarification document Gov. Gavin Newsom issued late Friday, all licensed marijuana businesses in California can continue with business as usual during an effective statewide lockdown implemented in response to the coronavirus outbreak.

The decision to categorize cannabis companies as “essential” in effect provides an economic lifeline to the marijuana industry by allowing MJ businesses to keep their doors open.

The entire cannabis supply chain – including all state-licensed MJ businesses such as farmers, distributors, manufacturers and testing labs – also are considered “essential” under the state policy, according to Nicole Elliott, senior adviser on cannabis in Newsom’s Office of Business and Economic Development.

Elliott noted there’s no differentiation between “medical” and “recreational” cannabis companies, which means every licensed marijuana business that chooses to continue operations during the lockdown can stay open.

In a separate news release, the state Bureau of Cannabis Control said: “Because cannabis is an essential medicine for many residents, licensees may continue to operate at this time so long as their operations comply with local rules and regulations.”

What about Californians who didn’t pay their landlords because the CDC has thus far blocked evictions and it was more important to purchase “essential” marijuana? “California Has a Plan to Pay the Back Rent for Low-Income Tenants. All of It.” (NYT, June 21):

A $5.2 billion program in final negotiations at the State Legislature would pay 100 percent of unpaid rent that lower-income Californians incurred during the pandemic and would be financed entirely by federal money. The state is also proposing to set aside $2 billion to pay for unpaid water and electricity bills.

The state’s separate rental relief program would be available to residents who earn no more than 80 percent of the median income in their area and who can show pandemic-related financial hardship. In San Francisco, a family of four would have to earn less than $146,350 to qualify.

So if you’re a working class American in the Midwest, paying rent on an apartment and paying taxes to the federal government, your hard-earned dollars will go to bail out California stoners earning $146,000 per year, so long as those Californians said “I prefer not to” when their landlords asked them to pay rent.

From 2019, when it was legal to have an in-person class at a college in San Francisco:

And, since it is Pride Month, we can take Pride in the Eros club (reopened long before the San Francisco Public Schools because bathing with friends is “essential”?):

(Of course I am Proud to have been in the Castro (dinner with a patent litigator), but I merely walked by Eros and did not go in. So my Pride level is only at 10 percent.)

Official business victimhood designations

A form from a university vendor portal, in which one is asked to enter one’s “Diversity Classification”. Here are the federally recognized victimhood categories for a business (including individual proprietors operating on a Schedule C basis):

Wouldn’t almost anyone qualify as “physically challenged”? Compare yourself to these four individuals who were chosen at random:

Wouldn’t you be at least 80 percent disabled compared to any of the above? (in the sense that you wouldn’t be able to do more than 20 percent of what they can do)

Our Juneteenth ice cream cake

From the weekend, our Juneteenth ice cream cake:

Togetherness and love for the chocolate and vanilla. Rainbow sprinkles to celebrate all of the varieties of love among humans (including poly!) that we valorize during Pride Month.

Provenance: We invited over an immigrant (from Switzerland) to celebrate National Immigrant Heritage Month (for those who seek to minimize the number of immigrants with whom they interact, Joe Biden says “America is, always has been, and always will be a Nation of immigrants.” (perhaps an unwelcome message for Native Americans!)) and she arrived with this cake in a box.

ICUs were clogged during coronaplague partly because relatives couldn’t visit

Our anonymous hero behind Medical School 2020 is working in a hospital now. Part of his residency training has included shifts in the intensive care unit. There he has gained some insight into why American ICUs became clogged during COVID-19 peaks.

“Hospitals wouldn’t let relatives come in to see the patients,” he said. “A patient with no long-term chance of survival can’t be unplugged with relatives approving ‘goals of care.’ But people are reluctant to approve unplugging a loved one if they aren’t able to see the patient and understand the patient’s situation.” In other words, without relatives coming into the ICU, the docs and nurses had no “goals of care” and therefore kept patients on ventilators for weeks after they would ordinarily have been unplugged.

Four weeks to flatten the curve (U.S. keeps the border closed)

From the Biden administration:

In other words… “4 weeks to flatten the curve” (“reduce the spread”).

How is this supposed to work? Can’t anyone come in from Canada or Mexico currently, so long as he/she/ze/they says that he/she/ze/they is seeking asylum? (“The Justice Department Overturns Policy That Limited Asylum For Survivors Of Violence” (NPR, June 16, 2021) says “in effect, restoring the possibility of asylum protections for women fleeing from domestic violence in other countries”, but the law should apply to people with all gender IDs, just as the “Violence Against Women Act” in theory can be used by those who identify as “men”. So if two people live together and say that they hit each other, both should be able to apply for asylum, emigrate to the U.S., and move in together to continue their domestic arrangements.)

You can sit on top of each other, but wear a mask

Part of an email from the local public school here in Maskachusetts….

To assist you in planning, our bus protocol for the fall includes:

  • All students/drivers will wear masks on the bus
  • Windows will be open at least one inch
  • No social distancing will be in place
  • Seats will be assigned

(i.e., the exact opposite of WHO advice prior to June 2020; even the simplest mask will stop an aerosol virus and therefore you should feel comfortable in a crowded indoor environment)

Happy Irrelevant Person’s Day!

Hallmark says that today is Father’s Day. The Harvard Gazette takes a different view with “Why living in a two-parent home isn’t a cure-all for Black students” (June 3, 2021):

New research suggests financial and other resources are also key to success for youth

So a plaintiff who pops a Clomid and has sex with a married dentist and harvests the resulting child support will have cash-yielding children that turn out better than if he/she/ze/they had married a medium-income person and stayed married. (Since a night of sex can pay better than a long-term marriage. Caution: this is true in Massachusetts, California, New York, or Wisconsin, but not in Nevada or Minnesota. See Real World Divorce for a state-by-state analysis.)

At least for Black children, parental income is the only factor correlated with success:

Rather than the two-parent family being the great equalizer that most Americans imagine it to be, Black children from low-income, two-parent families find themselves in the same position as Black children growing up with a single parent. This is what I found in my forthcoming study in the journal Social Problems. In it, I explore the differential returns to living in a two-parent family for Black youth’s academic success. Drawing on a nationally representative sample, I found that there were no differences in the earned grades, likelihood of grade level repetition, and rates of suspension between Black youth from low-income, two-parent households and their peers raised in low-income, single-parent households.

The government can save us:

What we need are policies that alleviate financial hardship and facilitate good, consistent parenting. President Biden’s proposed American Families Plan is an example of such a policy.

The Harvard folks don’t highlight that the Biden family is leading by example on the plan that is financially optimum for the typical American capable of incubating a baby (see “Hunter Biden’s child support is finalized with his stripper baby mama” (Daily Mail) and when does this grandchild get to visit the White House to see Grandpa Joe?).

Let’s see who is funding the soon-to-be-professor who informs us that #Science proves that low-income Black men are useless and the mom who rids her home of one of them in favor of pursuing full-time Tinderhood is doing the kids a favor:

The National Science Foundation paid for this scientific result with your tax dollars.

Sadly, wherever there is science there are science deniers. “Sorry, Harvard, fathers still matter — including Black fathers” (USA Today):

A new report from the Institute for Family Studies co-authored by us with sociologist Wendy Wang finds large differences between Black kids raised by their own two parents, compared to their peers raised by single parents (primarily single mothers). Black children raised by single parents are three times more likely to be poor, compared to Black children raised by their own married parents. Black boys are almost half as likely to end up incarcerated (14% for intact; 23% for single parent) and twice as likely to go on and graduate from college (21% for intact; 12% for single parent) if they are raised in a home with their two parents, compared to boys raised by just one parent. Parallel patterns obtain for girls. Equally striking, we also find that Black children from stable two-parent homes do better than white children from single-parent homes when it comes to their risk of poverty or prison, and their odds of graduating from college. Young white men from single-parent families, for instance, are more likely to end up in prison than young Black men from intact, two-parent homes.

Whether you’re white, Black, or don’t see color, if there are humans on this planet who refer to you as “Dad” … I’d like to wish you a Happy Irrelevant Person’s Day!
