It resembles Steem, and Bitshares, quite a bit.

Do not know yet if like Steem putting EOS on stake will get me more. It does however let me use the blockchain. The more I stake, the more I can use CPU time and Network storage.

Currently I am able to store 15MB for instance, which seems a bit overkill to me. But as more accounts start using the EOS blockchain the more that will drop.

Will let it stay stacked a bit longer to see how it works.

Starting on EOS right now can be somewhat complex. Questions about what to use as a wallet and how to be able to use dApps will come to mind. It is still early days...

In the meantime using your EOS for trading might be a safe choice, until things become more clear and easy to use.
