Use myetherwallet.com. It's confusing at first because it's so different from other wallets. I watched some videos this week on it. To transfer coins you simply use the same "Your Address:" for any of the coins you want to transfer in. You just put this address into the withdrawal selection in an exchange and apparently myetherwallet.com is smart and it knows what the crypto is. In making it so simple and so different then all the rest of the exchanges, it caused me some confusion/frustration.

I haven't moved mine yet because the exchanges I'm realizing only exist to rip people off with fees. How so? In Poloniex, you can only withdraw $2000/day unless you raise your security level. That means if you have to break up your position to send many smaller transactions, you get the flat fee for each transaction!!! If you could move it in one move you would only have the fee one time. You are eating up your position significantly by moving.

Then, if you try to get the higher security, they only allow this through use of an external webcam. This means you can't use one built into your computer and have to go buy one and set it up just to get a higher security clearance at Poloniex. With all of the massive increasing transaction volumes, I think we will find it's more profitable for the exchanges than even those of us who did well investing...
