I apologize if this is addressed already but I find this whole thing very interesting. It seems to me that requiring KYC after the crowdsale is too late.

How do you know if investors bought the crowdsale or bought on an exchange? Are you just planning to Disallow US citizens to convert regardless, just to be safe.

I'm not that worried about it, I just find this interesting as it is another example of how complicated regulating crypto-currencies is going to be.
