I've withdrawn bitcoin from my account at CEX.io to my wallet at bittrex but it doesn't show up in my wallet when I check the transaction at CEX I got this message "Output is unspent and has no children"
what shall I do now?
What's the wallet address you withdrew to?
Have you tried contacting their support, if not then do so.
Also, how much did you have in your wallet and what was the withdraw fee?
