So i'm using Blockchain.info as a wallet, i received some bitcoins to my wallet and inmediately after that i re-sent them to an exchange.
Incoming to my wallet: https://blockchain.info/tx/c8c49723e0355ab1624b4684bdb02d1cabd1ec9cc715b1f910a1accd60149f06
Being sent from my wallet: https://blockchain.info/tx/6da5fbf7e33c153555907602ca144ca7805ca021c13bcd076d395389f7290974
So both transactions, the incoming transaction to my wallet and my sent transaction from my wallet are confirming at the same time at blockchain.info.
My exchange says that even though my "sent" transaction to the exchange has 16+ confirmations the bitcoins have not been "pushed" to their wallet
So i am wondering, how can transactions be confirmed but the bitcoins not arrived? i use real addresses because i'm genuinely intrigued by this, so i want to be as clear as possible.
