Can Bitcoin Transactions be Made Private?

Posted by in categories: bitcoin, cryptocurrencies, privacy

The blockchain is public, yet a Bitcoin wallet can be created anonymously. So are Bitcoin transactions anonymous? Not at all…

Each transaction into and out of a wallet is a bread crumb. Following the trail is trivial. Every day, an army of armchair sleuths help the FBI. That’s how Silk Road was brought down.

The problem is that some of that money eventually interacts with the real world (a dentist is paid, a package shipped or a candy is purchased at a gas station). Even if the real-world transaction is 4 hops before or after hitting the “anonymous” wallet, it creates a forensic focal point. Next comes a tax man, an ex-spouse or a goon.

The first article linked below addresses the state of tumblers (aka “mixers”). They anonymize an open network by obfuscating the trail of bread crumbs.

The Race to Own One Bitcoin

Posted by in categories: bitcoin, cryptocurrencies, economics, finance

Owning one full bitcoin is becoming a recognized attainment goal. And thereby hangs a tale.

Is it just a numbers game? Isn’t the unit a bit arbitrary and meaningless?…

The logistics and the math are compelling. I recognized the importance of reaching this personal milestone more than 8 years ago. But I was a nobody. No one cared. Then, in April 2019, we started to see articles in legitimate venues about this concept—and articulated in exactly this way. I borrowed the title of this post from this article in Medium.

Who Says So?

Spending Bitcoin in person is easy (What happens in background is elegant)

Posted by in categories: bitcoin, cryptocurrencies, economics

Today, I was co-host of an online cryptocurrency symposium—taking questions from hundreds of visitors. A common question goes something like this:

Can Bitcoin be used in person—or
is it just for internet commerce?

Our panel had a moderator, and also an off-screen video director. As I cleared my throat in preparation to offer a response, a voice in my ear reminded me that it was not my turn. The director explained that another panelist would reply. It was a highly regarded analyst and educator in Australia. Realizing that that she was calling the shots, I deferred.

I was shocked as I listened to a far off colleague suggest that Bitcoin is not useful for in-person payments. I wonder how he explains this to the grocers, tailors, lawyers, theme parks and thousands of retailers who save millions of dollars each year by accepting bitcoin—all without risk of volatility and even if they demand to instantly convert sales revenue into Fiat currency.*

About the Fuss: Is Bitcoin really important?

Posted by in categories: bitcoin, cryptocurrencies, economics

This afternoon, an automated bot at Quora suggested that I answer a reader question. Quora is essentially an “Ask the expert” web site. It is the world’s largest, cataloged and indexed Q&A repository.

This is the question I was asked to answer:

Some pundits believe Bitcoin is a fad, while others seem to feel that it is better than sliced bread. I like sliced bread.* Is Bitcoin really that cool? —Or is it just a lot of Geeky hype?

One other columnist answered before me. Normally, I pass on an invitation, if a question has already been answered. But in this case, the individual answering the question has yet to see the light. He has wandered into the Church of the Blockchain, but he just didn’t realize that the man sweeping the floor is the prophet.

Does decentralized currency thwart crisis intervention?

Posted by in categories: bitcoin, cryptocurrencies, economics

Here is another economics/policy question that I was asked to address at Quora. It provides great fodder for a quick Lifeboat economics review.

The US used quantitative easing to deal with one monetary crisis, and a bailout of the automotive and banking industry to deal with another. If nations, economies or individuals begin to embrace a decentralized currency, they will inevitably shift away from government issued money. Won’t this hinder a nation’s ability to intervene in a crisis?

Answering this question goes to the very heart of the ethics and politics of cryptocurrency.

Yes. Without centralized control over monetary policy, government options for intervention in a money crisis would be severely limited. But this fact may lead to a false impression…

Profit from Bitcoin with out Investing or Trading

Posted by in categories: bitcoin, cryptocurrencies, economics

I find it encouraging that so many people want to know if they should get into Bitcoin. But, I am discouraged when I discover that “getting into” is a euphemism for investing, trading, flipping or HODL (Buy, then hold on for dear life).

Sure, Bitcoin is deflationary. If widely adopted, it is likely to increase in value. But adoption is being thwarted by traders. Today 95% of cryptocurrency transactions are by individuals or organizations buying or swapping cryptocurrency rather than using crypto to buy apples, a new car, or a family vacation.

Many people consider Bitcoin to be risky and not just as an investment! They think its risky to use a payment instrument. The perception of risk is associated with its widely fluctuating exchange rate. In the end, the exchange value won’t matter at all, because Bitcoin will be the money and not the dollar, yen, euro or pound. But, unfortunately, even though the argument for widespread adoption is compelling, it will not occur while we continue to see spikes and plunges on a graph.

Cars, Gold, Houses, Toys & Stock: What gives value?

Posted by in categories: bitcoin, cryptocurrencies, economics


The title of this post is intentionally misleading. We frequently discuss the traits that lead to value here in the Lifeboat Blog. But today, I was asked a more nuanced question: “What things will hold their value?

And there is a ulterior motive in being a columnist for Lifeboat. Analyzing the dynamics of durable value leads to some surprising conclusions about the money supply and what a society chooses to use as money. We’ll get to this at end of this post.


We know that value comes from supply and demand. There are no exceptions. But, we have not addressed the properties that make an asset hold value over the long haul. Let’s consider some examples…

How can Bitcoin be divided into small units?

Posted by in categories: bitcoin, cryptocurrencies, economics

As with other recent articles, this one was originally published as an answer to a member of Quora, a Q&A site in which I am a cryptocurrency columnist. And just like the previous one in this Lifeboat series (also posted today), this is a Q&A exchange with a newbie—a bitcoin beginner.

The question is simply: “How can Bitcoin be divided into units smaller than one?” While the answer may seem obvious to someone versed in math, statistics or economics, I see this question a lot—or something very similar.

I can explain by asking a nearly identical question; one that the enquirer can probably answer easily. The goal is to provide the tools to answer the question—and in a manner that helps the reader recall and make use of the answer in the future. This is how I approached an answer…


Puzzle me this: Can you divide 100 into smaller pieces? Of course you can! You just divvy it up. After all, it’s just a number.

Why is it impossible to create more Bitcoin?

Posted by in categories: bitcoin, cryptocurrencies, economics

This article was originally an answer to a member of Quora, a Q&A site in which I am a cryptocurrency columnist. The reader is a “Bitcoin beginner”. If you understand the nature and purpose of a blockchain, the political leanings of Satoshi or the economics of a capped cryptocurrency, then this reviews things that you already know. But sometimes, a recap can be fun. It helps ensure that we are all on the same page…

In a previous post, we have already addressed a fundamental question:

It has nothing to do with how many individuals can own bitcoin or its useful applications. It simply means that—if widely adopted as a payment instrument or as cash itself—the number of total units is capped at 21 million. But each unit can subdivided into very tiny pieces, and we can even give the tiny pieces a new name (like femto-btc or Satoshis). It is only the originally named unit (the BTC) that is capped.

But, this article addresses a more primitive question. (Actually, it is a naïve question, but this adjective has a negative connotation, which is not intended). I interpret the question to be: What prevents me from creating, earning or being awarded an amount that brings the total circulation above 21 million BTC?

Update: Building (and placing!) a Bitcoin ATM

Posted by in categories: bitcoin, cryptocurrencies, economics

A new section: Bitcoin ATM business model
has been added. Jump to “2019 Update

The good news is that building a Bitcoin ATM is easy and less expensive than you might expect. But, offering or operating them engulfs the assembler in a regulatory minefield! It might just be worth sticking to selling bitcoin on PayPal (visit this website for more information on that). You might also wish to rethink your business model —especially user-demand. That’s the topic of our 2019 update at the bottom of this article.

A photo of various Bitcoin ATMs appears at the bottom of this article. My employer, Cryptocurrency Standards Association, shared start-up space at a New York incubator with the maker of a small, wall mounted ATM, like the models shown at top left.

What is Inside a Cryptocurrency ATM?
