Samsung starts producing GDDR6 RAM for next-gen graphics cards
Posted by Shailesh Prasad in categories: bitcoin, computing
You can start getting pumped about the next generation of graphics cards, as Samsung has announced that it’s building the first-ever 16-gigabit GDDR6 chips using its 10-nanometer class technology. The news isn’t a complete surprise, as Samsung previously said that GDDR6 was coming when it unveiled 8-gigabit DDR4 RAM chips last month and won a CES 2018 Innovation Award in November.
“Beginning with this early production of the industry’s first 16Gb GDDR6, we will offer a comprehensive graphics DRAM line-up, with the highest performance and densities, in a very timely manner,” said Samsung’s Senior VP Jinman Han. The company also did a minor tease, saying the chips “will play a critical role in early launches of next-generation graphics cards and systems.”
The voracious demand from bitcoin mining has pushed the GeForce GTX 1070 from a $380 suggested retail price to $890.

Cryptocurency: Thoughts on a “Korea Krash”
Posted by Philip Raymond in categories: bitcoin, cryptocurrencies, economics
If you are reading this on January 16, 2018, then you are aware that Bitcoin (and the exchange rate of most other coins) fell by 20% today. Whenever I encounter a panic sell-off, the first thing that I do is try to ascertain if the fear that sparked the drop is rational.
But what is rational fear? How can you tell if this is the beginning of the end, or simply a transient dip? In my book, rational fears are fundamental facts like these:
- A new technical flaw is discovered in the math or mining
- A very major hack or theft has undermined confidence
- The potential for applications that are fast, fluid and ubiquitous
has dropped, based on new information*
Conspicuously missing from this list is “government bans” or any regulation that is unenforceable, because it fails to account for the design of what it attempts to regulate. Taxes, accounting guidelines, reporting regulations are all fine! These can be enforced. But banning something that cannot be banned is not a valid reason for instilling fear in those who have a stake in a new product, process, or technology.

Proof-of-Work Alternatives: Massive electric consumption by cryptocurrency mining
Posted by Philip Raymond 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 Philip Raymond 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 Philip Raymond 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 Philip Raymond 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 Philip Raymond 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 Philip Raymond 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?!
