This is a scam and a stupid one too. Each exchange creates a new wallet for you when you sign up. When you buying Bitcoins they go to your wallet and you can verify the transaction on blockchain.info. Remember that the blockchain is public!

An exchange who works like a normal eWallet, so your money are stored in their database only, is seriously suspicious. I understand there are people who will fall for these scams, but there are scammed people everywhere in the world.

Also, a serious bitcoin trader/buyer should always have the bulk of his Bitcoins on a personal wallet not on an exchange.

Transferring Bitcoin to an internal customer wallet on the public blockchain would be extremely expensive. Transaction fees are still north of $10 last I checked! So most every exchange combines wallets, and I don't think this will change anytime soon.
