ComebackToken.collectTheStatistics(uint256,uint256,address) (#665-682) uses a dangerous strict equality:
- crashTime == 0 (#673)
ComebackToken.collectTheStatistics(uint256,uint256,address) (#665-682) uses a dangerous strict equality:
- crashTime == standartValuation (#671)
ComebackToken.collectTheStatistics(uint256,uint256,address) (#665-682) uses a dangerous strict equality:
- lastBuyOrSellTime == 0 (#667)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract ownership is not renounced (belongs to a wallet)

Reentrancy in ComebackToken.addLiquidity(uint256,uint256) (#1007-1018):
External calls:
- PancakeSwapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1009-1016)
Event emitted after the call(s):
- LiquidityAdded(tokenAmount,bnbAmount) (#1017)
Apply the check-effects-interactions pattern.

ComebackToken.collectTheStatistics(uint256,uint256,address) (#665-682) uses timestamp for comparisons
Dangerous comparisons:
- lastBuyOrSellTime == 0 (#667)
- crashTime == standartValuation (#671)
- crashTime == 0 (#673)
- crashTime <= theData (#678)
Avoid relying on block.timestamp.

ComebackToken._rTotal (#535) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
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 version^0.8.0 (#1) allows old versions
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.
