My last post on Bitcoin got me some push back and I am glad that it did. I would rather be read, and disagreed with, than not read at all. I have been told that I know very little about crypto currencies and that I have much to learn, and I agree. The crux of the disagreements though lay in my classifying Bitcoin as a currency, not as an asset or as a commodity. Since this classification is central to how you should think about investing versus trading, and value versus price, and goes well beyond Bitcoin, I decided to dig deeper into the classification and provide even more ammunition for those who disagree with me to tell me how wrong I am.
