No, staking doesn't work. I have not received anything since 18th April, that is 6 weeks ago. And I have my computer 24/7 online because I mine on it. The wallet even says "staking".
This coin is a fucking joke and being shilled by people like it's second Jesus coming.
Staking is like mining with your balance - if you have a low balance, it will take ages until you get a block reward. It's similar to mining Bitcoin with a Raspberry Pi - just because you never get any rewards doesn't mean that the system itself does not work. I would recommend you to learn more about Proof of Stake:
