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.*

What is a ‘paper wallet?’ Do I need one?

Posted by in categories: bitcoin, cryptocurrencies, economics

This post is structured as a question-&-answer. That’s because it was originally an answer at Quora, a Q&A site at which I am a Bitcoin columnist.

What is a ‘Paper Wallet’

A paper wallet is the ultimate offline wallet. It simply means that the private address to your crypto wallet is printed on paper — either as a string of characters, a QR code, or a series of seed recovery words.

If you destroy any electronic copy of your original wallet (e.g. the private keys that give you access to your wealth), then hiding this piece of paper is very similar to hiding a bar of gold. The only way that someone can steal it or know the amount it represents is to get their eyes and hands on something physical. They would need to know that you tucked it into your mattress or behind a secret panel of your cellar wall.

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…

Lack of standards leads to new Bitcoin wallet advice

Posted by in categories: bitcoin, cryptocurrencies, economics

This update is an adaptation of my recent answer to a Quora reader who was in a panic. She asked:

What can I do after a hard drive crash?
How can I recover my cryptocurrency?

In the past, I would address the immediate problem of course. (My answer is below). But to prepare for the next unfortunate event, I recommended a wallet type based on a user’s unique experience, expertise and comfort zone. I guided the reader to weigh trade-offs of important criteria: Security, portability, convenience, and quick access to assets).

I had believed that some types of wallets were better for some individuals, but that they required a background in cryptography—or at least a discipline for meticulous practices. As CEO of the Cryptocurrency Standards Association, I had also believed that simple, unified, and popular standards would emerge very soon. I figured that this would enable users to practice safe-wallet maintenance in their own homes.
