When you import a paper wallet with 12.9000 bitcoins or whatever, it goes to your blockchain wallet, so when you want to import those into a new bitaddress paper wallet, do you use the "Quick Send" option? (I DON'T see a FEES option there?? where is it?) Or do YOU use the "Custom Send" option? what are the differences? Last but not least, So I wanted to send 5 bitcoins and I have 12 in the blockchain hot wallet now,  if you don't send them all 12.9000 to that paper wallet and just 5 does the other 7.9000 become "Change" and wth is change anyways? does it automatically make a change wallet or is it lost? (someone said it would be lost forever??) or does it remain in the blockchain hotwallet untouched until you move the rest?   Thanks, Im a noob still.
