In a recent speech at the annual PNWER meeting held in Montana, Neil Kashkari, president of the Federal Reserve Bank of Minneapolis, sharply criticized cryptocurrencies, stating that "95 percent of cryptocurrencies are fraud, deceptive advertising and noise," and he also said he had a more positive view of cryptocurrencies in 2015. Kashkari also referred to the large number of altcoins and called them "garbage coins."
Most of the banks also said the same thing. I think they are worried about the existence of crypto at the moment so that it makes bank transactions not run normally. And the profits they get from money transactions in the bank will decrease. But in the end they also returned to crypto by making digital money. They are just ashamed to admit the greatness of blockchain technology. If banks currently utilize blockchain technology, then they will be more profitable than fiat currency transactions.
