I owe Jack Shaw a favor. It’s one of those, “This one time in Cambodia…” type of favors. We won’t speak of it beyond perhaps a nod and wink. It’s not written down anywhere; the details of such are so vague as to be almost non existent, while encompassing the known universe. It expires upon death, of the sun; and can be redeemed whenever and by another person who need only walk up to me and say, “Jack Shaw sent me. He says to tell you ________”. And tada, that favor has been redeemed for value.

Jack would call this favor a “marker.” It’s more valuable than your house, the Empire State Building & 100k Bitcoins combined. It can even be redeemed for something even more precious, my time or an opportunity or access to my network. You know, those things that money can’t buy. Well, you can lease my time from time to time.

Favors, markers and promises are humanities’ first virtual currencies.

It is an eye opening video. In the financial climate we are now I am not shocked that these Miners are losing based on costs.

I wrote an article on the Wave Chronicle regarding the Crypto-Currency Crash and some of the changes that could be made to make this particular market effective for those who actually want to use Crypto-Currency as a vehicle for purchasing.

Join me for a quick review of the spikes & dips in the Bitcoin exchange rate. This time, it’s all about one very simple chart. _{[continue below graphic]…}

The chart below shows a history of BTC price spikes, dips and recovery. Click to enlarge, then start at the top—and move down.

• • • Consider the percent-pullback after each spike (red label)
    • Think about the stellar rebound after each drop (green label)

The table at right illustrates why I do not get too worked up over the plunge in the BTC exchange rate. There are no fundamental flaws in Bitcoin math or mechanisms, the market need for benefits conveyed by Bitcoin is terrific, and popular arguments against Bitcoin are severely flawed. Skeptics and Critics typically say this:

Abstract: The term “blockchain” has caused much confusion and damage due to its failure to accurately capture the core characteristics of decentralized byzantine fault tolerant systems. In this article, a restoration of an older term is proposed as replacement.

The question asked in the title has been edited from what was asked today at Quora, the Q&A forum at which I participate as expert columnist. The original question was a bit more ambiguous: “Which is better? — a digital bitcoin wallet or a physical one?” I have included the original question, to better distinguish products and terms. All bitcoin wallets are all digital—even a paper wallet, whether a character string or a QR code. Conversely, an exchange may use “physical” wallets to host client assets, individual application wallets, or they may simply keep records of client assets that are stored, collectively, in their own master wallet. To complicate matters, Bitcoin is never really “stored” by you or an exchange service. It is stored on a public blockchain, where assets and transaction history can be traced through time by anyone. Therefore, all forms of user access are “digital”. What the reader really wants to know is “Which form of access control is better? — custodial or personal?” Type 1: Custodial Wallets are Managed by a Trusted Party They hold your assets. You view a statement balance—just like a bank account.

Today, I will talk about the recent creation of really intelligent machines, able to solve difficult problems, to recreate the creativity and versatility of the human mind, machines not only able to excel in a single activity but to abstract general information and find solutions that are unthinkable for us. I will not talk about blockchain, but about another revolution (less economic and more mathematical), which is all about computing: quantum computers.

Quantum computing is not really new, as we have been talking about it for a couple of decades already, but we are just now witnessing the transition from theory to realization of such technology. Quantum computers were first theorized at the beginning of the 1980s, but only in the last few years, thanks to the commitment of companies like Google and IBM, a strong impulse has been pushing the development of these machines. The quantum computer is able to use quantum particles (imagine them to be like electrons or photons) to process information. The particles act as positive or negative (i., the 0 and the 1 that we are used to see in traditional computer science) alternatively or at the same time, thus generating quantum information bits called “qubits”, which can have value either 0 or 1 or a quantum superposition of 0 and 1.
