So i just opened a Blockchain.info wallet after years of using Bitcoin-qt.
My Blockchain.info wallet had an empty wallet, i sent some bitcoins to it and right after that without waiting for confirmations i sent some bitcoins to satoshidice just to test. To my surprise the transaction went through, how is this possible if my bitcoins didn't even have 1 confirmation?
If Blockchain.info "lends" me bitcoin, how can it do it?
