Hmm. I see it clearly on blockchain.info. Check it here: https://blockchain.info/tx/37af67b65c75a08c79baf6d9e9c9aca573e9f2f0ac64d7f2d628629374699e8b
OP, your problem is clear as day here. The transaction only has 45 sat/byte. This might have been a good enough fees, but right now the network is so congested that this will never go through. Right now I think the minimum amount of fees are about already 700 sats/byte to get a transaction to go through within the day. I guess your only hope now is to have it accelerated or if you have enabled increase fee option then you should do so. This will take forever to confirm without doing anything.
So many thanks fr your reply: now what can i do to get this Transaction in my bittrex i did some more transaction after this and those got me quickly i dont understand this kind of things can you advice me what should i do?
