Kexcoin missed their funding goal and the ICO has failed.
However, there are still more than 200 holders of the coin, what's up with you guys?
Refund
You have to put up a sell order for your Kexcoin at 0.0025 BTC/Kex, which was the buy-in price and should be honored by Kex.
at the time of writing, there were no buy orders up at the ICO price. Could take some time until Kexcoin refills their wallet, or you need to get in contact with them.
Anyways, I would not sell for less, and make them aware.
