Sorry guys, I'm a newbie and have been reading quite a few pages of comments to try to understand what's going on. No luck.

I have some ETHD on coinexchange. I can obviously trade them but...I read about the possibility of a swap with tokens. Why do we need to swap? What happened? What is the benefit? Are the tokens trad-able?  

If you don't swap, what happens to my ETHDs?

Now ETHD are being traded on EtherDelta. Are those the 'old' ETHD?

Thanks in advance for the clarifications.
