Hi Sean   I think 1st you have to down load and open your client. Then I would check at poloniex but the way  I understand I'd when you transfer your pre fork ether to the exchange you get an equal amount of etc . I would definitely research a little more but that's how I understood at the update post on polo

YES..avoid sending any ETC (if you have it) to GDAX/ Coinbase.
It is not being credited there at this time..things appear pretty wacky the last few days as the dust settles and exchanges decide to list ETC trading pairs...Kraken announced a few hours ago they are now listing ETC

Thanks for the Upvote!..I wanted to follow up and share this link with you I pulled off the ethtrader subreddit this morning..similiar question to yours and some excellent answers/links from users:

I believe that you should have both. You need to make sure that when you move the coins that you are moving them on the right fork, or else you will lose the coins. Im not sure what solutions there are to make sure you dont fuck up at the moment but check out the forum im sure 1000 people are asking the same questions.

Well,i would stay away  from ETC actually.
The problem is that there was a lot of hacks , and hackers own a really big amount of ETC, so if it comes to dumping, it may erase ETC actually.

Wow...you haven't even put it in a wallet since the crowdsale? I'm actually curious about how you would go about activating it. If you just sent it to a Coinbase wallet then it would most likely just be ETH kind of like what I have going on with Kraken where it seems to just be ETH. Not sure exactly though.

This whole ETH/ETC thing seems pretty crazy to me. Both sides have interesting arguments, but what's more interesting to me is that there is market support for both. Makes me think the whole crypto world is just a little... out there.

aaaaaaah!

The ETH crowdsale is from the start of the chain,right? Both chains countains your eth... if you could "activate" it on ETC, that is the question. Best of luck.

If you had ether before the fork then you have both.

If you have both eth and etc. As the eth was created in the genesis block and etc has the same genesis block.  You can open the json file in note pad and it will show which eth address it is sitting on if you want. That address will be the same on both chains right now.

You can then check how much etc you have here:

Now as for moving one without the other that is a little bit more tricky. You can use the splitter contract at address 0xaa1a6e3e6ef20068f7f8d8c835d2d22fd5116444 to split them(Vitalik talks about it here https://blog.ethereum.org/2016/07/26/onward_from_the_hard_fork/).


But if you are trying to keep the genesis eth wallet untouched that won't work. What you can do is transfer one etc into the address that you know won't be on the regular eth blockchain and then transfer the whole amount of etc over to a different address. 

You can do the same with eth just move a after fork eth over and then move all the eth.

Im not happy with ETC. would like to hear others opinions.

Maybe You could ask Poloniex :-)
Seriously, they double (ETH + ETC) the deposits of the traders, surely they should know a pair of things about your question.
