I would add Steem to that list. For me the most valuable cryptocurrencies are those that people use to do things. Steem is one of the most widely used blockchains with the Steemit blogging platform being the most popular use case. But they are also used to run other popular platforms like Dtube (a blockchain version of Youtube), Magic Dice (Gambling) and DrugWars (Game).
i would support adding STEEM on the list, specially on these prices that are far from ATH, when calculate number of posts per day on Steemit and connected platforms based on STEEM and current valuation and compare with, for example social media platforms like Facebook, valuation per post and user is lower, and Steemit has more than 1 million users, so will be here for sure
