Neel Kashkari, president of the Federal Reserve Bank of Minneapolis, who for years has been one of the fiercest opponents of cryptocurrencies, once calling them "worthless", "fraudulent" and "nonsense", recently said he would be open to cryptocurrencies. "I'm going to keep an open mind," Neel Kashkari said in an interview in New York on Tuesday. Still, Kashkari questioned the significance of cryptocurrencies during the conversation. He said the industry has been around for a long time but has not yet seen widespread adoption, suggesting it lacks practicality.
