Are you sure that leaving your coins in an online wallet without holding your private key a better idea?
I don't even use Blockchain's online wallet nowadays as they don't allow multiple addresses to be sent at once (when you send to more than one recipient), as well, for privacy reasons, they change the address with new and the "change" remains in the old one (which can be used again in future but you don't hold your private key). I think Electrum needs to be used with care (if anyone's suggesting OP with electrum, please ask them to download the upgraded version 3.0.5 to forgo the bugs).
