Hello, nice to have you here!
Yes you will be rewarded on average 3% per year for whatever amount you are holding in your wallet.
When the next version releases you will be rewarded through a share retirement process as SWIFT will become more scarce over time as more nodes participate and use the network modules.
The network is based around a concept called incentive centered design.
You can read more about this concept here:
