ETH has to regain trust.
ETC has to survice the hacker dump.
Im not sure what the status is with replay attacks.... its all a f***n mess.
Yes... and most of the activity is short term speculation. Look at the volume : ETC turned-over several times its total market cap in the last week.
The 'battle' may take some time, and there will be a mess for months to come. This could be good for new ideas, making code better, but I can't imagine any profits accruing yet : the speculators always fund the innovation, that's how it's supposed to work.
meanwhile... someone wants to launch a fork of ethereum, CETH (I don't know) if someone already posted it:
