When I sent from the pool to the wallet it was super fast. However, when I sent from my wallet to bittrex it took 15mins. I'm currently still waiting after 35 mins while sending from bittrex to ccex. Any explanation for this?

edit: 55 mins later I'm at two confirmations.
edit: almost 2 full hours and I'm only at 6 confirmations.
final edit: So it ended up taking a little over two full hours to send. I'm over it.
