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:
https://github.com/bitcoinx2/tutorials/wiki/Proof-of-Stakeit works, yes.
but there doesn't seem to be a fair mechanism (if any at all) to compensate for not accepted stake rewards.
i for example have had really bad luck with not accepted stake rewards until now.
i don't get a reward very often because i'm only staking little over 500 xspec but most of the times when i got one it was not accepted.
so i think there should be some kind of compensation for not accepted stake rewards within the pos system.
I think you misunderstand the concept of PoS here. The 'not accepted' stake rewards are your mining attempts at "solving" a block. Your wallet will generate PoS transactions constantly using your UTXOs to generate a hash value that is compared to a network generated hash based on numerous values including the last block accepted by the network. This is very much like Bitcoin mining. The 'orphaned' transactions you see are simply PoS transactions generated by your wallet software that do not match the network generated hash value it compared against. In Bitcoin mining, it's similar as the miner generates hash values to compare with a network generated hash value. If you have a very low balance you will be much less likely to generate a "winning" hash value much like a small miner will have a low chance of "solving" a block. When your wallet generates a PoS transaction that meets the network criteria this transaction is accepted by the network and other transactions are added to the block and you get the reward.
So, your wallet is constantly generating PoS transactions and a hash value derived from that transaction, like a Bitcoin miner constantly generates hash values. The algorithm takes into account your balance, so the higher your balance the higher the probability of generating a "winning" block. There is a difficulty adjustment like Bitcoin that aims to control the block generation time.
A lot of people misunderstand PoSv3 so have a look at this:
