for now.. I know the Cryptocurrency / Crypto Innovation is divided into 14 categories;
(Storage, Privacy coin, Social, Market Prediction, IOT, Lightning Network, Payment, Dapp, Stable Currency, DEX, Exchange Token, Dapp Platform, IFO, Games).
according to you whether the category of Cryptocurrency / Crypto Innovation will increase because of the many new concepts that emerge.
Privacy coins dont exist. They are just a cryptocurrencies. Money have to be fungible. And for a cryptocurrency to be fungible it needs opaque ledger. It is silly to call coins private, if they are just what money should be.
