FOMO3D was created by the same people that created PoWH3D. They make insanely fun games and social experiments on ethereum. This one simulates the creation of an ICO exit scam. There will be two versions of this game, the long con and the short scam. Right now, there is only the long con due to high ETH gas prices.
The game begins by buying keys. A key is pretty much a token that gives you dividends. The game ends when the timer runs out, but buying a key extends the timer 30 seconds. The timer is capped to 24 hours. When the timer runs out, the game ends letting the person with the last key have all the ETH in the pot(~6000 ETH right now).
Even if you do not buy the last key, you still earn ETH dividends back everytime another key is purchased. At any time you can withdraw this or reinvest. Each time a key is purchased the next key will cost more. Eventually leading to a point where the exit scam will end and the last person will have the key, earning the pot. I believe this will go on for a long time, since a key right now is only a minuscule part of the pot.
You don't have to just take my word for it though. Everything here can be verified on the ETH Blockchain. Here is the contract address.
Right now, this is very profitable, I invested a measly $60 and already in an hour I have earned back $4. Not to mention if you are lucky you can get massive ETH airdrops.
Although, I would never suggest you invest more than you can afford to lose. But this contract quickly became the most popular contract on all of ethereum.
