SAFEBET.withdrawToken(address,address) (#718-727) ignores return value by IERC20(_token).transfer(_account,tokenBalance) (#726)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

SAFEBET.constructor(uint256) (#437-455) uses a dangerous strict equality:
- require(bool)(block.number / 10 == marketingWalletPercentage) (#452)
Don't use strict equality to determine if an account has enough Ether or tokens.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

SAFEBET._tokenTransfer(address,address,uint256) (#576-603) performs a multiplication on the result of a division:
-fee = amount * transactionTax / denominator (#590)
-receiveAmount -= (fee * _creditsPerFragment) (#591)
Consider ordering multiplication before division.

SAFEBET._tokenTransfer(address,address,uint256).fee (#582) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

SAFEBET._approve(address,address,uint256).owner (#548) shadows:
- Ownable.owner() (#340-342) (function)
Rename the local variables that shadow another component.

SAFEBET.setCasinoWallet(address).wallet (#690) lacks a zero-check on :
- casinoWallet = wallet (#692)

SAFEBET.swapAndLiquify(uint256) (#605-618) uses timestamp for comparisons
Dangerous comparisons:
- marketingETH > 0 (#614)
Avoid relying on block.timestamp.

SAFEBET.transactionTax (#390) is set pre-construction with a non-constant function or state variable:
- liquidityTax + marketingTax + casinoTax
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.8.6 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.
