The readily available information, to me, about Bitcoin or other cryptocurrencies, including that provided by financial notables on media such as CNN, has not allowed me to comprehend them in any real sense. So I am left with my own speculative powers to try to arrive at what they might possibly be and their possible consequences. Firstly, in my opinion, for them to have value in the financial markets -even in the fields of art or intellectual property- they must be a scarce resource. Secondly, this means that the rate at which they could be "manufactured" or "mined," as the case may be, given that they have been loosely defined in the televised media, at least, as numerical solutions to complex mathematical problems, presumably defined by equations, must be naturally or effectively legally constrained to such a degree that their value in the secondary market not decrease, at least not monotonically, lest this failure lead to their crash with potentially devastating consequences on the larger economy, national or even global, depending on the capitalization levels reached at such times. Thirdly, they, each instance or coin, must be unique and thus distinguishable from every other, and their respective ownership distinctly attributable to a specific owner or group, and registered as such, for any real possibility of fraud or theft to be precluded in their design. Fourthly, they must not be allowed to be used in money laundering or drug trafficking or any illegal or proscribed activity, if they are not to eventually present a threat to global political, social, or economic stability or world order and development. This, for starters.
