I'd like to point out something very important which is currently someone sent in a transaction of 19 BTC - https://blockexplorer.com/address/1GCgBLjxEjeJs5PKt7TJgUdZDDsnViANVc and it's currently stuck / very slow to confirm because of the fee used (0.00002302 BTC), please use an appropriate fee when sending in coins since you will not be credited until there are 3 confirmations!! That is a scam transaction now that I look at it hard. It shows the total Estimated BTC Transacted to be only 0.00007698 BTC.
Maybe someone try to get you to credit the account with the btc so they can try and withdrawal it. I hope you did not do that.
