How to withdraw Bancor from app?
you cannot do that yet. They were locked for 7 days.
Is this written somewhere in a SmartContract (if yes, can you point me there?) or is this just what you have heard somewhere?
I believ it was in the terms.
Hitbtc seems to be causing a stir with these iou (i owe you ) they are not BNT tokens they are iou tokens which represent Hitbtc's BNT that they bought in the ico. when the chain is live anyone with hitbtc iou will get the equivilant BNT in their trading account.
Usually when they do that, is the price close to what it is after listing on real major exchange like bittrex ?
No it is not. The IOU's are good for flipping if you can buy them early but that is it. HitBTC controls the (very limited) supply so the price of these things basically always rises.
My god just use your brains, why the hell would anyone buy a token for 20x it's price when they could've just participated in the ICO which did not have a cap.
People are actually buying at even more than x20, so three option : people are stupid and the price will crash, hitbtc are faking the market or the price will even go higher than that
