I was always ok with bittrex until they introduced the new verification things but don't worry, I'm sure that everyone will receive the coins cause bittrex hardly fails.
Yeah they introduced that and locked your coins and then ask for basic verification and tell you you still need to send them IDs if you want your money back... Plus their tickets takes ages, I font know about ignis but it think they won't even give it to people, they are to greedy and there are better exchanges out there now.
