ICO price was around 5000sats

Can't believe people are dumping it below ICO price on tidex.

If that is true (wth is tidex?), they are the pre-ICO buyers, they got each token for a lil over 2 cents of dollar, so they can dump it for the ICO price and make profit. When this minority is finished dumping, no one else will sell the tokens below ICO price.
If they are gonna do that, isn't it more profitable to just accept back the original ETH?
