Re “Popping the bitcoin bubble’’ (Opinion, Jan. 3): As the author correctly states, Pets.com launched at $14 per share, only to collapse a short time later, but is this comparison legitimate? Blockchain as a technology will revolutionize significant portions of our information technology infrastructure, processes, and business models. It makes just as much sense to believe that one or more of the blockchain projects emerging will turn into the blockchain version of Amazon, Facebook, or Google. What we are witnessing now is simply the gold rush, but those of us who have been present and working in the blockchain community for more than two years know what to be looking for in terms of value creation. So yes, some coins will tumble, some will disappear, but some will grow to become giant global networks.
