renounceOwnership() should be declared external:
- Ownable.renounceOwnership() (#688-690)
transferOwnership(address) should be declared external:
- Ownable.transferOwnership(address) (#696-699)
Use the external attribute for functions never called from the contract.

Contract ticker (BSC-Coin) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
Pragma version^0.8.0 (#4) 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.

Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (#256-267):
- (success,returndata) = target.call{value: value}(data) (#265)
Low level call in Address.sendValue(address,uint256) (#188-193):
- (success) = recipient.call{value: amount}() (#191)
Low level call in Address.functionDelegateCall(address,bytes,string) (#312-321):

Low level call in Address.functionStaticCall(address,bytes,string) (#285-294):
- (success,returndata) = target.staticcall(data) (#292)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
