Contract ownership is not renounced (belongs to a wallet)

Contract ticker ($DEWO) 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.

DecentraWorld._transfer(address,address,uint256).developmentFee (#1106) is a local variable never initialized
DecentraWorld._transfer(address,address,uint256).taxDiscount (#1110) is a local variable never initialized

DecentraWorld._transfer(address,address,uint256).marketingFee (#1105) is a local variable never initialized
DecentraWorld._transfer(address,address,uint256).DEWOTokenTaxes (#1155) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

DecentraWorld.setRecentTx(bool,address,uint256) (#922-930) uses timestamp for comparisons
Dangerous comparisons:
- txSettings.lastTx[_sender].add(txSettings.txcooldown) < block.timestamp (#923)
Avoid relying on block.timestamp.

-require(bool,string)(exclueFromMaxTx[_sender] == true || txSettings.sells[_sender].add(_amount) < txSettings.sellMaxTx,Sell transaction limit reached!) (#914-918)
Remove the equality to the boolean constant.
