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."
It's partially right and wrong. Because the traders will inverse and hold two years blindly, the coin will ended on listing and supply. Then it became a garbage coin. Only huge potential coin will long lasting and get bulk profit for the initial investors. Doge coin is good example for that, huge people earned bulk in short period.
