Assume I have a private key or collection of private keys, and I am afraid they have been compromised by a third party. I am also expecting payments at an unknown time in the future to arrive to one or more of the private keys.
Is there any trustworthy software or website that automatically forwards any bitcoins received at one or more addresses to a new address, as soon as possible? Perhaps even by increasing the fee a bit beyond the normal 0.0005 BTC to have a better chance at pushing through a transaction before someone else did?
It must be possible. I had redeemed some old bitbills by sweeping the private key to my blockchain.info wallet. I then much later tried to temporarily store some coin from my bitcoinspinner app on my android by sending to that private key while I rebooted my phone. Unfortunately, the coin was instantly swept out of that private key at my blockchain.info wallet to some unknown address, and I lost my coin! Another bitter lesson.
