Coin.constructor() (#146-156) performs a multiplication on the result of a division:
-deadAmount = _tTotal / 100 (#147)
-_tOwned[_route] = deadAmount * 5 (#148)
Coin.constructor() (#146-156) performs a multiplication on the result of a division:
-deadAmount = _tTotal / 100 (#147)
-_tOwned[address(0xdEaD)] = deadAmount * 90 (#149)
Coin.constructor() (#146-156) performs a multiplication on the result of a division:
-deadAmount = _tTotal / 100 (#147)
-_tOwned[FTM] = deadAmount * 5 (#150)
Consider ordering multiplication before division.
