I tried to withdraw 5 Bitcoin (! not Fiat) from MtGox a couple of hours ago. It`s confirmed in the transaction history, but does not show up on blockchain.info (and not where it was supposed to go either, of course).
Their support hasn`t answered my request yet. Could not find info wether some other people have the same problems.
This is standard. It can take upto a few days for a bitcoin transaction to go through. Welcome to mtgox.
This is not standard, it does not take a few days for bitcoin transactions to go through, they happen instantly.
