If cryptorush accidently gave you too many zeitcoins then give them back to cryptorush. The dev should be building bridges and mending relationships with cryptorush. How can we expect to get more exchanges to trade zeit coin if we cannot work with the few we already have. The first step is helping cryptorush rebound so if they gave you too many coins, do the right thing and send them back.
The perspective should be a wider one with more focus on the future and a sincere desire to get over the speed bumps from a rocky start. I guarantee the other exchanges are watching. No exchange wants to take on a coin that is a huge risk.
