The conclusion of this research is that users should stay away from using common passphrases to generate Bitcoin private keys, and despite the complex cryptography utilities used to build Bitcoin, the services security can still be sabotaged by the maligned practices users employ when choosing. Shor's algorithm, a quantum algorithm for factoring integers (that's how it would attack cryptography is a better path, they write. Future improvements to quantum technology allowing gate speeds up to 100GHz could allow quantum computers to solve the PoW about 100 times faster than current technology. captain spaulding, the researcher also revealed that a potential hacker could use the basic Amazon EC2 account to check over 500,000 Bitcoin passwords per second. Bitcoin wallet bitcoin vedonlyönti urheilu password (Wallet key or private key) of a user or a group of users and then use it to transfer all the bitcoins from users wallet to his anonymous wallet.

Executing such type of hacking is very difficult and requires help from insiders of Internet Service Provider, given that it requires inside access to an ISP.
For example, here is the table of keysearch rates at bitcoin wiki page : And here are few reports from users for different GPUs: i7 8700K - 3Mkey/c GTX 980TI (v1.42) - 73Mh GTX 1050ti - 23 Mkey/c GTX Mhkey/s GTX 1080ti - 108 Mkey/c. So It is Practically Impossible to Undo Payments in this case. For more details about the address, see this bitcoin wiki page. Source 1 Source.
