There is a noteworthy technical application case to pay attention to.

According to publicly available information, this individual used technical means to discover and exploit system vulnerabilities on certain gambling platforms. He then cleverly replaced the platform's commission address configuration, causing the commission funds that should have flowed to the platform to be entirely redirected to his own account.

He maintained this operation for several years, accumulating a considerable amount of results—currently, the two different investigation departments have seized a total of 183 Bitcoins, illustrating how long the accumulation period must have been.

This incident reflects two phenomena: first, that some online platforms indeed have vulnerabilities in their smart contract and fund flow security protections; second, that even after accumulating a large amount of crypto assets, risk management and legal compliance remain unavoidable hurdles. For users participating in DeFi or other on-chain activities, this serves as a reminder—technological advantages may bring short-term gains, but systemic risks and regulatory pressures will never disappear.
