I am currently able to process 2^54.75 Keys/second using a program I've been writing that combines the best of Bitcrack with BSGS using GPU's, at the moment im only capable of getting these speeds while searching public keys, while searching public address compressed Im still getting about 2^38.127 Keys/second. I will be discussing this program more and maybe releasing a copy for public use after I find the 64 address!
What's the point of looking for 64 puzzle today? On the Internet, everyone is shouting that whoever finds 64 puzzle still won't get anything.Since there are many robots per transaction that work to intercept.
The only way someone can "intercept" is if when BTC moves from wallet, the pubkey will be exposed, and someone with kangaroo can quickly find the priv key. But many people have said to use electrum(?) and to uncheck the replace by fee option.

In this situation; Once someone finds the private key, won't they be able to transfer the money to another wallet? Is it possible to transfer money instantly by paying a high fee?
