i spoke with them and they said lost , 15,000  gone
what a blow to the heart

i just did the same, them adding bch to coinbase messed me up
sent 15,000 bitcoins to Bch and coinbase rep said lost , gone
very upsetting

I WAS JUST GONT TOO FAST AND COPIED MY BITCOIN CASH WALLET  FROM COINBASE AND SENT  BITCOIN TO IT FROM BITTREX 
WHAT CAN I DO,  VERY UPSETTING
DO I CONTACT BITTREX ?  OR COINBASE 

ANY ADVICE

   i dont know what to do  ?  contact  bittrex and ask to reverse   ?
bittrex holds the keys ? correct

transferred bitcoin from bittrex to coinbase  (bch wallet)   accidentally coppied the wrong address/wallet
