Bloomberg columnist Noah Smith recently published an article claiming that all hype is wrong, and the bitcoin and encryption worlds may still change the world, but not what people originally thought. He believes that the blockchain revolution will not happen, and the blockchain ecosystem is not decentralized and independent as one might imagine. In addition, technology does not protect anyone from scammers and villains. His conclusion is that even if the blockchain is a very important technological advancement, it is possible to change something, but it will not change the whole world alone, and the technology has not proved itself, it is still an expensive solution. Immerse yourself in chaotic competition and fraud, as well as technical difficulties and human error.
