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.

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?

Blockchain will make sure green pledges aren’t just greenwash: a new initiative

Posted by in categories: bitcoin, drones, internet, satellites

Blockchain will make sure green pledges aren’t just green wash.


When a country or a company makes a promise to reduce carbon emissions, respect fishing quotas or cut toxic output, how can we be sure they’ll keep their word?

The truth is, it’s often extremely hard. But a new initiative — Global Ledger — led by a group of World Economic Forum Young Global Leaders (YGLs) aims to change that.

Facebook’s digital currency may force central banks to create their own

Posted by in categories: bitcoin, cryptocurrencies, finance

Just a few months ago, Augustín Carstens, the general manager for the Bank for International Settlements (BIS), the so-called central bank for central banks, said his organization saw no value in the potential of central-bank-issued digital currencies. Well, he’s apparently had a change of heart, and the entrance of Facebook and other “big techs” into financial services appears to be the reason.

The news: Carstens told the Financial Times that the BIS is supporting the “many” central banks currently developing or researching digital currencies. “And it might be that it is sooner than we think that there is a market and we need to be able to provide central bank digital currencies,” he said.

The context: Many other central bankers have dismissed cryptocurrencies like Bitcoin, which tend to be volatile and whose most popular use has been speculation. But Facebook’s proposed digital currency, Libra, will be backed by fiat money and designed to maintain a stable value.

Facebook’s Libra Cryptocurrency Just Resuscitated Bitcoin

Posted by in categories: bitcoin, cryptocurrencies

Bitcoin reached the highest value the popular cryptocurrency has had in the last 16 months — $11,251.21 — on Monday.

And Facebook is likely to blame. Analysts suggest that the social media giant’s recent unveiling of its own cryptocurrency called Libra likely bolstered investors’ confidence in crypto across the board, according to Agence France-Presse. Though Bitcoin never really recovered from its massive crash in late 2017, the recent resurgence is a sign that the cryptocurrency isn’t quite fading away as some believed.
