What exchange to use in order to withdraw cryptocurrency after ICO?
Why do you want to withdraw your coins after ICO ? ICO investment is not a short term investment.
you won't get any profit from that. i recommend you to hold your coins until the price is good enough.
As I see, some altcoins cost less some days after being launched. First day may be one of the most profitable. Then the price could go down
