My withraw was very fast 5 min.
I asked to withdraw 9 bitc, one day after, it is still pending. Something wrong with hashnest?
They appear to have only 10
BTC in their hot addresses. Your delay is probably to put more coins into the address from cold storage.
I just did a withdrawal and the coins came out instantly (your transaction should be broadcast now) - although my withdraw was merely 0.0402 as a test.
