CoinToken.handleTax(address,address,uint256) (#890-994) uses a dangerous strict equality:
- taxSum == 0 (#929)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.
