Minting adds ETH to the shared prize. Burning an NFT makes you the latest burner. If nobody mints or burns for 4 hours, the latest burner can claim all collected ETH.

How It Works
Mint an onchain NFT to add ETH to the Mass. You can keep it, transfer it, or burn it. Burning makes you the latest burner. After the first burn, 4 hours with no mint or burn lets the latest burner claim all collected ETH in the Mass.
Mint whenever you want, with up to 25 NFTs in each transaction and no wallet limit. The first public NFT costs 0.0026 ETH. Each public mint raises the next price by 0.00005 ETH. Your exact total is shown before you confirm. Of each payment, 95% enters the Mass and 5% goes to the developer.
Burn 1 to 25 NFTs you own in one transaction. Burned NFTs are gone forever. Each burn lowers the next mint price by 0.00005 ETH and makes your wallet the latest burner.
The game can end only after somebody burns a regular NFT. Every mint or burn restarts the 4-hour clock. If the clock reaches zero, the latest burner can claim all collected ETH in the Mass.
NFTs #1–10 are minted to the developer wallet at launch, then distributed to community members, contributors, and people who help Green Hole grow. They cost 0.02325 ETH together, add ETH to the Mass, and move the public price to 0.0026 ETH. They cannot be burned. The owner of each can claim 1% of the current Mass once. The latest burner receives all ETH still in the Mass when the game ends.
