Hi Alberto, thanks for your comments. Let me start by saying that Bitcoins are divisible by up to 8 decimal places, so they can ultimately be divided into smaller units for purchases of low-price point products. In terms of the bigger picture, money is what money does. Whatever people use as a medium of exchange is money. The world already has multiple forms of currency, and not just government sponsored. There are a variety of digital currencies in existence at present - though each of the competitors to Bitcoin have some sort of company, group or organization in central control. In addition, there are non-conventional currencies. For example, in prison, people use cigarettes. No doubt countless other people in locations all over the world can and do currently use unconventional forms of money. I think the real issue is whether or not a network effect is achieved. How common is the usage of bitcoin by retailers and businesses? How common is the usage of bitcoins for employers to pay salaries and compensation? How common is it for consumers to prefer Bitcoin to their local currencies? There is a tipping point where enough users adopt the system that it make it very, very difficult to eradicate. Just like the government sponsored currencies are now...
