Low Severity Issue
Out of gas
Issue:
The function includeInReward() uses the loop to find and remove addresses from the list. Function will be aborted with exception if there will be a long excluded addresses list.
b. The function _getCurrentSupply also uses the loop for evaluating total supply. It also could be aborted with exception if there will be a long excluded addresses list.
CONCLUSION
Smart contract do not contain any high severity issues!
