I'm quite new to bitcoins so apologies if i'm being a noob, but I'm very confused!
My bitcoin-qt wallet balance says I have 2.0113406 BTC (which is what I expect).
Now if you check my transaction history: http://blockchain.info/address/1HvxJibwAAyVqcNY5GVUWvHSwgYybpRGTp
It says that I only have 0.0123506 BTC?
I think the confusion stems from the transaction I made to satoshidice. It says I sent 2 bitcoins to satoshidice but i only actually sent 0.01. Further inspection yields that I actually sent 0.01 to satoshidice and the remainder to address 1EHYT8dFMcDVnkkE9kEoH5T3PBb3bRZdmP. What is that address? Is that one of my addresses that I don't know about?
What's going on?
