Bitcoin money transfer
Weird. If you don't mind, could you add a transaction I'd and your bitcoin wallet address?

I'm guessing you withdrew into your bitcoin wallet from circle, but it didn't appear in your bitcoin wallet. You could however see it on the blockchain?

I have a couple of ideas:


Malware


You may have malware installed on your computer that swaps out your bitcoin address that you have copied down to the hacker's bitcoin address. Please verify that the recieving address in the blockchain is the same one as the one in your wallet.

Wallet not synced


If you're using a wallet like bitcoin core/qt, you will have to wait for your wallet to sync. It will show at the bottom of the client.
