Gasccoin.sendETHToFee(uint256) (#293-296) sends eth to arbitrary user
Dangerous calls:
- _developmentAddress.transfer(amount.div(2)) (#294)
- _marketingAddress.transfer(amount.div(2)) (#295)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Additional information: link

Gasccoin.rescueForeignTokens(address,address,uint256) (#303-306) ignores return value by Token(_tokenAddr).transfer(_to,_amount) (#305)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.

Combination 2: Unchecked transfer + 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.

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.
