Virtual Currencies Are As Old As Favors

Posted by in categories: bitcoin, cryptocurrencies, disruptive technology, economics, finance

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.

BTC plunge: Why I don’t worry

Posted by in categories: bitcoin, cryptocurrencies

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:

Best Bitcoin wallet: Hardware or hosted?

Posted by in categories: bitcoin, cryptocurrencies
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.
