In our experience, releasing software before it's ready is never a good idea. And the main reason for the ICO is so that we can get it ready faster.
We try to answer all the questions as they come in, but keep in mind that a) we're a small team and b) it's a very busy time for us - just 10 days until we launch the ICO. Bear with us.
So, we're getting this a lot. Just to avoid any issues (including human error), we advise people to generate a separate ETC address. It's free and takes a minute, so why take unnecessary risks?
