I'm using the latest QT version 5.6.1. I sent 2 transactions to my coinbase account but neither have gone through. The transaction details are as follows:
Transaction ID: ca0810139641342c1f0191bdb55e848770ae4941fc811b70e395eb15abc29ab5
Amount: 0.01 ltc
Transaction ID: 0604b999aacdb7192da9d387cab09bd0d36ffc20348d7dded6bf65b2af5e620d
Amount 100 ltc
Fee: 0.1 ltc
The first transaction was sent 14 hours ago and I didn't include any transaction fee, so I guess that's why. But the second transaction was sent 9 hours ago and I included 0.1 transaction fee but it still hasn't gone through.
So I used blockchain explorer to check both transactions and the first transaction details looked strange. Even thought I only sent 0.01 ltc, the blockchain shows transacted value of 2.86720496 LTC, with 2.85720496 LTC going to one address and 0.01 ltc going to my coinbase wallet. I tried to abandon the first transaction on QT but it didn't seen to do anything.
