What does STORJ pay?

So, I'm curious, what exactly does STORJ pay? Is it a fixed amount of cryptocurrency per task completed, or does it vary based on some other factors? Are there any incentives for users to participate in the network, like rewards for storing more data or maintaining a high level of uptime? And how does STORJ's payment system compare to other decentralized storage solutions? I'd love to hear more about how the economics of STORJ work and what kind of returns users can expect for their contributions to the network.
