It's also another self-mining contract on Ethreum blockchain but it's too very complicated for me and very confusing, for this reason, I'm out!
Sorry to hear you're finding it complicated! Let my try to facilitate a bit;
By purchasing ClusterTokens, you participate in the self-mining structure of the contract.
Instead of having rewards each block, you'll have to be patient to receive the rewards.
Every block mined on Ethereum adds 1 UNIT to the counter of ClusterToken.
Every 1000 UNITS, this becomes 1 SEGMENT.
Every 1000 SEGMENTS completed, 1 CLUSTER is generated by the contract.
At current value, this equals to 100 Ethereum.
The 1 CLUSTER (100 Ethereum equivalent) then get's distributed amongst all mining participants multiplied by how much you invested.
If you like, you can also claim your rewards at each SEGMENT, but you'll only receive half the rewards you would if you waited.
TL;DRIf you buy some ClusterTokens, you'll automatically participate in the mining rounds and are eligible for a piece of the 100 Eth equivalent reward every 1.000.000 blocks.
