No one is well-known in the United States, perhaps abroad. However, more and more listed companies have added "blockchains" to their names and claimed to invest in blockchain technology, mining operations and certain cryptocurrencies, causing stock prices to soar. Is there anything else?
On-Line plc, a company listed on the London Stock Exchange (LSE), recently added the term "blockchain" to its company name, which has quadrupled the company's market value overnight. In the future, there may be a large Wall Street brokerage listed company becoming a Bitcoin futures trader, but it has not happened yet.
