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.

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.
