Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.
Not a direct threat, but may indicate unreliable intentions of developer. Both name and ticker of current token are widespread, i.e. common across multiple tokens. This is slightly suspicious
Redundant expression "this (Context.sol#21)" inContext (Context.sol#15-24)
Remove redundant statements if they congest code but offer no value.

bitcoin.totalFees (bitcoin.sol#36) is set pre-construction with a non-constant function or state variable:
- DOGERewardsFee.add(liquidityFee).add(marketingFee).add(burnFee).add(buyBackFee)
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.
