Jackpot.swapBnbForBUSDToken(uint256) (#1291-1304) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: bnbAmount}(0,path,address(this),block.timestamp) (#1297-1302)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Jackpot.swapBack(uint256) (#1306-1346) ignores return value by BUSD.transfer(address(team6Wallet),busdAmount * team6Fee / totalBNBFee) (#1340)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Jackpot._transfer(address,address,uint256) (#1166-1253) uses a dangerous strict equality:
- from != owner() && from != presaleAddress && from != presaleRouterAddress && automatedMarketMakerPairs[from] && ! automatedMarketMakerPairs[to] && block.number == tradingActiveBlock (#1202)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.

Jackpot._transfer(address,address,uint256) (#1166-1253) performs a multiplication on the result of a division:
-fees = fees * 4 (#1242)
-fees = fees.mul(sellFeeIncreaseFactor).div(100) (#1245)
