HyperCheems.sendETHToFee(uint256) (#647-649) sends eth to arbitrary user
Dangerous calls:
- marketingAddress.transfer(amount) (#648)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

HyperCheems._transfer(address,address,uint256) (#588-635) uses a dangerous strict equality:
- block.timestamp == launchTime (#605)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link


Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Contract ticker (Hyper Cheems) 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.

Redundant expression "this (#11)" inContext (#5-14)
Remove redundant statements if they congest code but offer no value.
