Proof-of-Work Alternatives: Massive electric consumption by cryptocurrency mining

Posted by in categories: bitcoin, cryptocurrencies, economics, energy, environmental

Some blogs and news outlets eschew long titles. Publishers want readers to scan a list of topics that fit on one-line each. But, a better title for this article would be:

“Massive electric consumption by cryptocurrency mining:
An unfortunate environmental nightmare will soon pass!
… Proof-of-Work alternatives are on the horizon”

A considerable amount of electricity is used in the process of mining Bitcoin and other cryptocurrencies. Miners are effectively distributed bookkeepers, and this use of resources is part of a system called “proof-of-work”. It keeps the books fair, honest, and without an ability for the miners to collude (In other words, they cannot ‘cook the books’).

Is Cryptocurrency Good for Government?

Posted by in categories: bitcoin, cryptocurrencies, economics

Today, editors at Quora asked me to answer a seemingly simple question:

“Is cryptocurrency good for government?

This is a terrific question, and one that I write about frequently. The question gives me a chance to summarize the key facets of widely mistaken fears. But, here, in the Lifeboat Blog, there is room to elaborate a bit.

In the first phase of cryptocurrency adoption (we are in the midst of this now), there is an abundance of skepticism: Misunderstanding, mistrust, historical comparisons that aren’t comparable, government bans & regulatory proposals—and a lot of questions about intrinsic value, lack of a redemption guaranty, risky open source platforms, tax treatment, etc, etc.

Say it again, Bitcoin Investors: “Bad News is Good News”

Posted by in categories: bitcoin, cryptocurrencies, economics, government, policy

By now, every interested news-junkie is aware that Bitcoin plummeted from $15,000 to $13,000 (USD exchange rate) on January 11, 2018. This morning, every news outlet and armchair analyst attributes the drop to the Korean government signaling that it will ban Bitcoin trading among its citizens.

With Donald Trump and Kim Jong Un butting heads over nuclear missile tests and the upcoming Winter Olympics, you would think that South Korea has other priorities than banning Bitcoin.

As with all news—except accidents—the Korean plans were known by a few insiders (in this case, government bureaucrats), and so the influence on value was bigger than the drop that occurred after the news story. In the days before this “event”, it was probably responsible for a drop of about $4500 in exchange value.

Listen up Wild Ducks! We have heard this before. On Sept 11, China announced the exact same thing. I wrote about it in the most popular article of my 7 years as Blogger: Bad News is Good News for Bitcoin Investors.

What if you Send Bitcoin to a Non-Existent Address?

Posted by in categories: bitcoin, cryptocurrencies, economics

I get this question a lot. Today, I answered it at Quora.com. But, here, in the Lifeboat Blog, I have more bandwidth to elaborate.

Question:

What if I make a typo when sending Bitcoin. The recipient address
may be invalid or it may belong to another individual. —But there
is a third possibility. Couldn’t it be a valid address, but without any
wallet that can receive it? I bet the blockchain catches these errors
—Right? Will I always get my money back?

The short answer:Don’t worry, it cannot happen. That won’t happen either. Sure, it’s possible. That’s wrong, and You’re screwed!

Revenue Neutral model reduces altcoin investment risk

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

Titles are chosen by editors and not journalists or experts. I fought my editor over the above title. Yes, I address the teaser—and I explain a solid altcoin investment model. But, that comes after the break. The first part of this article should be titled “Why would anyone quote cost or value in Bitcoin?”. The subjects are highly related, so bear with me…

Today, a reader asked this question:

Some financial sites discuss value in Bitcoin terms, rather
than dollars or Euros. Why would I calculate the value of a
new car, my rent or an investment in this way? It’s hard to
understand how much money I need!

Answer: Your right! It’s difficult to estimate the value of a car or your rent in terms of Bitcoin. You are paid in dollars or Euros—and your landlord quotes rent in the same currency.

Why does anyone attribute value to Bitcoin?

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

Oh, Cheez…We’re back to this question, again!

As a Bitcoin columnist, I get this question a lot. Today, an answer was requested at Quora.com, where I am the lead contributor on cryptocurrencies:

“Clearly, some people value Bitcoin. But How can
this be? There is nothing there to give it value!”

Many individuals, like the one who asked this question, suspect that Bitcoin was pulled out of thin air—and that it is not backed by gold, a government, or an authoritative redemption guaranty. After all, it is just open source code. What stops me from creating an ElleryCoin using the same code?!

How does the Blockchain ‘know’ you have printed a paper wallet?

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

Let’s say that you no longer trust your currency exchange to host your Bitcoin wallet and you don’t trust a Trezor or Nano hardware wallet. You don’t trust your memory and you don’t trust your kids. And you certainly know better than to keep your wealth in your PC or phone. That would be downright crazy—right? What can you do?!

A growing number of people are printing paper wallets. It is the ultimate form of security. Some individuals even delete their cloud wallet, leaving everything to a string of hex characters or a QR code printed onto a slip of paper. (NB. You had better be certain that you and a few trusted individuals know how to find that piece of paper!)

But here’s an interesting mystery. If you print the paper wallet off-line and delete your other wallets, then how can the blockchain ‘know’ that you have changed wallets? The short answer: It doesn’t and you haven’t!

Let’s explore a bit deeper…

Should we ‘out’ Bitcoin creator, Satoshi?

Posted by in categories: bitcoin, cryptocurrencies, economics

Everyone likes a good mystery. After all, who isn’t fascinated with Sherlock Holmes or the Hardy Boys? The thirst to explore a mystery led us to the New World, to the ocean depths and into space.

One of the great mysteries of the past decade is the identity of Satoshi Nakamoto, the inventor of Bitcoin and the blockchain. Some have even stepped forward in an effort to usurp his identity for fame, infamy or fortune. But in this case, we have a mystery in which the subject does not wish to be fingered. He prefers anonymity.

This raises an interesting question. What could be achieved by discovering or revealing the identity of the illusive Satoshi Nakamoto?…

The blockchain and Bitcoin present radically transformative methodologies with far ranging, beneficial impact on business, transparency and social order.

Is Bitcoin a Store of Value?

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

Bitcoin has many characteristics of a currency. It is portable, fungible, divisible, resistant to forgery, and it clearly has value. Today, that value came close to $20,000 per coin. Whether it has ‘intrinsic value’ is somewhat of a moot question, because the US dollar hasn’t exhibited this trait since 1972. Today, economists don’t even recognize the intrinsic value of gold—beyond a robust, international, supply-demand network.

Lately, Bitcoin is failing as a viable currency, at least for everyday consumer transactions. The settlement of each transaction is bogged down with long delays and a very high cost. The situation has become critical because of squabbling between miners, users and developers over how to offer speed transactions or lower the cost of settlement. Bitcoin forks and altcoins such as Dash and Bitcoin Cash demonstrate that these technical issues have solutions. Since Bitcoin is adaptable, I believe that these issues are temporary.

But an interesting question is not whether Bitcoin will eventually become a consumer currency. it is whether Bitcoin can distinguish itself as a store of value, rather than just an instrument for payment or debt settlement. After all, a Visa credit card, a traveler’s check and an Amazon gift card can all be used in retail payments, but none of them have value unless backed by someone or something. US Dollars on the other hand are perceived as inherently valuable. They carry the clout and gravitas of institutions and populations, without users questioning from where value arises. (This is changing, but bear with me)…

What about Bitcoin? Does owning some bitcoin represent a store of value? Yes: It absolutely does!
