I bought some HAT tokens on 1/1 from etherdelta. I am not sure if these are the old or new coins. I sent them to the address for the swap about 4 hours ago because that is what I read i was supposed to do. I haven't received anything in my account. How long does it usually take to send the tokens back? Did I already have the new tokens? If I sent the new tokens to the address do they just send them back?

Thanks
