Good summary of what Cardano is.

To complement your post, the only wallet that is available to store ADA is Daedalus, but they recently release Icarius which is a lightweight implementation of Daedalus, which will run as a chrome extension.

Another very important thing to mention is that so far Cardano is centralized. They will be working on with different staking pools now during the autumn to implement the decentralization features in Shelley. For more info check out the cardano roadmap
