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."
There is no need to argue this because he is right although the percentage might not be true. The truth is that, most of these altcoins are just here for the money, that is, their team have nothing to offer other than to create a platform, launch a coin, get it listed and if possible pump the price and gradually let it go. With the inception of DEX, nowadays it is very easy for any project to launch, and most of them goes directly for marketing or promotions without having anything to show for, and just like that gradually they list and a lot of them exit scam within hours of listing.
That's for new projects, what about old projects? How of these projects that raised a lot of money in public fundraising event are still around, and what even happened to the money?
Therefore in essence, he is right and that is also the reason why we need to go for projects which will make impact, that is projects whose use case is applicable and the team already working towards it.
