Use safeTransferFrom and safeTransfer
Summary
ERC20 standard allows transferF function of some contracts to return bool or return nothing. However, Some tokens such as USDT return nothing.This could lead to funds stuck in the contract without possibility to retrieve them.
Recommendations
I recommended to use safeTransferFrom and safeTransfer in SafeERC20.sol.
