The article you linked has a poor understanding of what cryptocurrencies are. First, understand that cryptocurrencies are not just money or currencies. Crypto-assets are programmable and allow many different applications, it's not just limited to purchasing transactions. Realize that there may be many different types of crypto-assets. Some will allow voting & governance, some will have price-stabilizing incentives built in, some will be inflating and mimc fiat, while others will be programmed to mimic gold, some will be interest bearing, some will be non-fungible, some will be a mixture of various properties and incentives. The term "cryptocurrencies" is really misleading.
