According to https://www.btc-echo.de/exklusivinterview-serokell-ceo-seroka-ueber-wuetende-maenner-und-gute-ideen/ the development team is preparing building dApps on Cardano. Looking forward for the first real uses casess written in Haskell!!!
According to Cardano's last roadmap update the staking pools should be availabke for testing by Q3.
The big thing with the staking pools in Cardano: you can delegate partially or fully your ADA shares to a staking pool for a small fee, and from that moment your delegated share will create returns in form of extra coins.
Although my upvote is small I am happy to share it with you.
