The growing popularity of digital currencies has aroused mainstream interest in blockchain technologies and their possibilities. Increasingly, blockchain is used as a generic term that most people associate with Bitcoin, the digital currency created using the technology. The potential and scope of the application of decentralized protocols have already become so much broader.
Bitcoin is dividing opinion on Wall Street, with a rush of investment banks expressing widely divergent views on the cryptocurrency boom.
The rally in bitcoin has been supported by the growing interest from institutional investors. Some companies, prominently including Tesla, have also loaded up. US Federal Reserve chair Jay Powell, meanwhile, said at an event on Monday that crypto assets are more for speculation than for payments.
