Source

MyScheme.sol — a 100 ETH chain-letter Ponzi using a binary tree payout structure.

Three public read functions:

• getContractBalance() — returns treeBalance (storage slot 0)
• getNumInvestors() — returns numInvestorsMinusOne + 1 (slot 1)
• getNumNextLevel() — returns myTree.length - numInvestorsMinusOne - 1 (available tree slots)

The fallback function accepts 100 ETH deposits, inserts the sender into the tree, and executes the payout algorithm when a tree level fills up.

Key difference from the 10 ETH variant (0xa327075a): when numInvestorsMinusOne <= 2, the 100 ETH version simply sets treeDepth = 1 (no immediate send to myTree[0]). The 10 ETH version sends the entire balance to myTree[0] at that point.
