FBL [FootballBattle] Token

Contract ownership is not renounced (belongs to a wallet)

FBL.mintAvailable(string) (#573-577) performs a multiplication on the result of a division:
-(((block.timestamp - budgets[name_].withdrawLast) / budgets[name_].withdrawDuration) * budgets[name_].withdrawable) (#576)
Consider ordering multiplication before division.

FBL.mintBudget(string) (#559-567) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(budgets[name_].withdrawLast + budgets[name_].withdrawDuration <= block.timestamp,invalid duration) (#561)
FBL.mintAvailable(string) (#573-577) uses timestamp for comparisons
Dangerous comparisons:
- (budgets[name_].withdrawTotal >= budgets[name_].budget) || (budgets[name_].withdrawLast + budgets[name_].withdrawDuration > block.timestamp) (#574)
Avoid relying on block.timestamp.
