Since we aim to push marketing hard, we have applied the majority of the transaction tax into this. This will ensure the project and the investors benefit from continued price action. Funds will also be used to develop the various use cases of the token.

LOTTERY
4% of the transactional tax will be applied for the lotteries we will be running, such as the smaller monthly holder lottery, and the larger fitness challenges.

DeflationaryERC20.swapBufferTokens() (#408-432) sends eth to arbitrary user
Dangerous calls:
- address(teamWallet()).transfer(half) (#429)
- address(lotteryWallet()).transfer(otherHalf) (#430)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.


Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

DeflationaryERC20.swapBufferTokens() (#408-432) performs a multiplication on the result of a division:
-half = contractETHBalance.div(txFeeTeam + txFeeLottery).mul(txFeeTeam) (#427)
Consider ordering multiplication before division.

Pragma version=0.8.11 (#7) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
