/**

3Days2Live is a blockchain gamified innovative social experiment. Our goal is to continue to create advanced innovative contracts on the Ethereum Blockhain with the goal of advancing the current blockchain Gaming Meta. Upon all the tokens deployed on Uniswap are being launch-out, we will delpoy another smart contract and the game will start, winners will be rewarded with ETH collected from the token tradings.

Please refer to the website for more detailed info on the project/game.
