Sprint._transferFrom(address,address,uint256) (#273-310) uses a dangerous strict equality:
- firstbuy[recipient] == 0 (#281)
Don't use strict equality to determine if an account has enough Ether or tokens.

Sprint.takeFee(address,uint256,address) (#319-342) performs a multiplication on the result of a division:
-feeAmount = amount.mul(totalFee).mul(multiplier).div(feeDenominator * 100) (#332)
-stakingTokens = feeAmount.mul(stakingFee).div(totalFee) (#333)
Consider ordering multiplication before division.

Sprint.swapBack() (#375-414) ignores return value by router.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,autoLiquidityReceiver,block.timestamp) (#404-411)
Ensure that all the return values of the function calls are used.

Sprint.totalFee (#179) is set pre-construction with a non-constant function or state variable:
- rewardsFee + marketingFee
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.

Pragma version0.8.12 (#20) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.12 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.
