About URG-U

Website
URG-U is part of the UrGaming Ecosystem and is the token for the URG University platform. The objective of this platform is that the players of different competitive video games can buy courses to improve their skills, dictated by the best players from each of these games. This platform will allow the best players in the world to generate a passive income with each of the sales made on this platform, helping them to improve their income and financial stability, which in e-sports is something really difficult to achieve.
URG University will solve this problem, supporting the highest level players as well as those streamers who also want to sell their courses through this platform in order to improve their income as well as the stability of their profession.
The platform's business model will allow the URG University's earnings to be reinvested in buying the same URG-U token, in this way, it will help to boost the price of the token and thus benefit all its holders. In addition, marketing once the platform is already online, will be massive, focusing mainly on the main function that is education within video games in order to attract those who want to improve their skills and results.

Contract ticker (URG-U) 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.
UrGaming2.Burn(uint256) (#1206-1210) performs a multiplication on the result of a division:
-tBurn = tAmount.mul(_Burn_FEE).div(100) (#1207)
-rBurn = tBurn.mul(_getRate()) (#1208)
Consider ordering multiplication before division.

Ownable.unlock() (#460-465) uses timestamp for comparisons
Dangerous comparisons:

Address._functionCallWithValue(address,bytes,uint256,string) (#358-379) uses assembly
- INLINE ASM (#371-374)

UrGaming2._takeLiquidity(uint256) (#988-992) is never used and should be removed
Remove unused functions.
Additional information: link
UrGaming2._previousBurnFEE (#725) is set pre-construction with a non-constant function or state variable:
- _Burn_FEE
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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#358-379):
- (success,returndata) = target.call{value: weiValue}(data) (#362)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable UrGaming2._getRValues(uint256,uint256,uint256,uint256,uint256).rTransferAmount (#967) is too similar to UrGaming2._transferBothExcluded(address,address,uint256).tTransferAmount (#889)
Prevent variables from having similar names.
