It depends, there will be a refund period for antshares project. Now is more than 5k btc in 2nd ico, if people withdraw 1k btc during refund project, no doubt that it will influence the price of ans. And if whales invest more in last 2 days, they will gather more fund. So the price will be estimated accurately after 2nd ico and refund period.
I already have 18 Antshares, probably the worth will be less than Bitshares.
