// This is the HOLDTOWIN token contract.
// A method to play the crypto lottery in a passive way. One ticket will qualify holder for all drawings as long as user holds 7ADD.
// Prize will depend on the amount of tokens transacted. -1.25% of all transactions will go to Jackpot-
// Community will decide how much you will have to hold to be included into drawings for 1 chance.
// There is a 1.25% burn of 7ADD erc20 token on any transaction.
// There is a 1.25% fee of 7ADD erc20 token that will be added to the prize.
// Total fee when you buy 7ADD erc20 token = 2.5% * 1.25% burn and 1.25% to jackpot * 
// Total fee when you sell 7ADD erc20 token = 2.5% * 1.25% burn and 1.25% to jackpot * 
// Total fee when you transfer 7ADD erc20 token to any other address = 2.5% * 1.25% burn and 1.25% to jackpot * 
// Lottery prizes will be sent by Jackpot Account after the draw is complete - 1.25% of the Jackpot amount will be reported to the next draw - 1.25% of the Jackpot amount will be burned
// 7ADD is a deflationary token.
// Anyone can contribute to the Jackpot by sending erc20/eth/NFT to the Jackpot Account. Prizes will be distributed as per senders wish. Contact us if you want to contribute to the prize.
// Deployer Account / Jackpot Account and UNISWAP addresses are not participating in draws.
// Team funds -5%- WILL participate in draws.
// Team funds account 0x57f4e37255767190962874D85C98082Ed31c59fB - Team will receive funds by Deployer transfer - 5% of total supply.
// Marketing funds will be spent directly from deployer accounts to avoid double burns. All marketing receivers WILL participate in draws if minimum amount is available- 5% of total supply.
// All decisions about the prize and pariticpation amount will be taken by community via snapshot.page decentralized voting.
// Good luck!
