A notable one.
I quote the last sentences:
Though only available in fixed, limited supply, Bitcoin has demonstrated the demand for an exchange currency not controlled by a central authority. There is no central point to shut Bitcoin down. You can’t point a gun at a prime number and expect things to change. And we all know how effective governmental attempts to shut down peer-to-peer networks have been. The digitalization of entertainment disrupted copyright monopolies, 3D printing machines are disrupting production monopolies, and crypto currencies are going to disrupt transaction monopolies.
Nobody can predict the long-term possibilities for Bitcoin. Either Bitcoin is worth zero, or is worth 10,000 to 100,000 each. It will take years for the market to figure out which it is. Until then, don’t expect Bitcoin to go away.
