Cryptocurrency decentralization is a useful tools of we getting back the power stole from us and giving us our right and privacy to do what we want and not to be monitored and controlled over your asset.

Is there any solution of centralizing a decentralized organization in other to take control of illegal activities in crypto world?

I don't really think there is a solution to centralizing a decentralized organization and that's because a decentralized organization is already decentralized and can't be controlled by other people anymore except you signed it yourself.

So let's cryptocurrency world be decentralized

There is now a new internet technology blockchain based that is a decentralized form of internet activities were hive and pob is built on that is WEB3.

Web3 is gradually taking over web2 and the difference is WEB3 is decentralized while WEB2 is centralized.
So decentralization will take over the world activities sooner or later so there is no reason for centralizing a decentralized organization
