ethcoin Token

EthcoinToken.distributeDividend(address,uint256) (#620-622) ignores return value by IERC20(ethAddress).transfer(shareholder,amount) (#621)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.
