I really want to apologize I'm just not that good at computers. I have ETH with Coinbase and i moved some over to. Bittrex  and now I'm going to buy some less expensive coins.  All that is going well I'm trying to figure out what is my best way to get this out of the exchanges because everyone says there not safe. I know this is been asked before but I feel really lost.  when you take coins how to put them off-line ?paper wallet?
 Is there a cost that the exchanges charge you for moving them in and out ?
