Continues to pump out from various places and some are not even in effect yet.
Right now we have

• Airdrop for another 300 days 400million SPS tokens or 13.33% of the supply
  Each month 37,500,000 tokens will be dropped (Reduced by 1% every month)
• 7.5 Million Ranked battles (not yet added)
• 7.5 Million Staking rewards per month
• 7.5 Million Liquidity pool incentives (I think this is CUBs DEC pool but I'm honestly not sure)
• 6.25 Million Land Expansion (no details on this yet as land isn't used)
• 3.75 Million Oracle Rewards (used to decentralizes the system and create swaps between exchanges)
• 2.5 Million Tournament Prizes (I've seen these active as of late and it costs SPS to get in which I think are burned?)
• 2.5 Million Guild Brawls (I haven't seen this added in yet.)
