Webchain... I'm obviously biased but:

Team that created
- https://coinimp.com (63 000 users and growing where everyone can just click in browser to start mining WEB)
- https://webchain.network (currency made in similar way to ethereum, but with custom mining algorithm optimized for javascript)
- https://mintme.com (crowdfunding exchange, everyone can create their own token for free, with market and allowing monetization similar to patreon)

and connected it all together, so people can easly get it via coinimp and mine it to try out a little, while at the same time giving real use case for currency itself (base for tokens creation)

same team that earlier created hosting business used by over million users

market cap 122,356 USD
1 WEB costs 9 satoshi

while you might argue for some reason it won't be top10, current evaluation seems really down.
