We all know that Chinese aren't that far behind in terms of technology. In fact, theirs are advancing at a fast rate. Even though they hold the sufficient technology to crack or generate the same private keys to Satoshi's addresses, it still is a resource-consuming and time-consuming effort to recover those coins. SHA-256 is secure enough to be cracked by our technology for the next couple of centuries, and I doubt that even with the world's most advanced computers today, the algorithm would be cracked within a short span of time.
