Frequent flyer miles should be a crypto

Posted by on Oct 3, 2014 in Thoughts | No Comments

This morning I woke to an email I had received from British Airways saying my 7,000 frequent flyer Miles where about to expire.  I had spent a few years living in the UK and with no intention to return, I didn’t have a need for these *points* anyway.  These Miles or points, are effectively a token.

Crypto-inflation

Posted by on Sep 30, 2014 in Technical, Thoughts | No Comments

Throughout this article I will reference Bitcoin, however the same logic applies to all cryptocurrencies available today. Many people once touted fixed supply as one of Bitcoin’s strengths.

Calculus is the language in which God wrote the universe.  Differential equations exist everywhere in nature.  An example is the predator prey model (Lotka–Volterra equation).  The population of rabbits grow;  as there an increased supply of prey for the foxes to eat so the population of the predator (foxes) also grow.  This of course creates […]

BTC & LTC: GST, VAT, TVA, IVA & PPN

Posted by on Sep 21, 2014 in Merchants, Payments, Thoughts | No Comments

Last week’s Meetup was about buying and selling Bitcoins, but as often is the case, discussions often wander across a range of interesting topics. That week someone asked about tax implications and I thought it was an important enough topic worthy of further investigation. We had two tax accountants in the audience so some of […]
