HOLD Token

HOLD.takeOutTokenInCase(address,uint256,address) (#885-887) ignores return value by IERC20(_token).transfer(_to,_amount) (#886)
HOLD.swap(uint256) (#936-942) ignores return value by this.transferFrom(_msgSender(),address(this),amount) (#939)
HOLD.swap(uint256) (#936-942) ignores return value by IERC20(USDT).transfer(_msgSender(),amount.mul(1).div(10)) (#940)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

HOLD._transfer(address,address,uint256) (#944-979) performs a multiplication on the result of a division:
