FOMO3D:
FOMO3D is a decentralized game with a rather simple premise. Users can buy one or more tokens (“keysâ€) using ether and the ether used for the purchase is sent to a smart contract (“potâ€). For every key bought, 30 seconds is added to a timer. The last person to buy a key wins the whole pot.
Users competitively buy keys in order to be the last key holder when the timer gets to zero, all the while increasing the value of the pot. Key holders are paid a small portion of the pot as dividends the whole time, further incentivizing them to participate in the whole [Ponzi] scheme.
So far, the pot contains about 26,000 ETH, and each key costs a 0.0054 ETH (~$2.50). The contract is scheduled to drain in about 24 hours, but the time keeps increasing with every key purchase. The cost of each key keeps increasing slowly over time, depending on the amount present in the pot. The whole process is supposedly run via smart contracts in a decentralized, trustless manner, with no human intervention.
PoWH3D:
PoWH3D (“Proof of Weak Hands 3Dâ€) is a “unique cryptocurrency exchange which allows you to trade Ethereum for P3D tokens. P3D tokens are ERC-20 tokens with a clever twist: every P3D holder receives direct earnings in Ethereum every time that anyone else buys, sells, or trades the token based on the amounts of tokens (in % out of total amount minted) held. The whole idea is that there will be more buyers facilitating ether to P3D holders.
While the game seems to be an obvious case of a pyramid scheme at first, it is more nuanced and complex than that.
