Which one do you prefer, centralization or decentralization?

[Putih]

With the decentralization system I am more free to manage the assets that I have, and do not feel bored with the rules of third parties, that is the reason I prefer decentralization.

Both are good. Each has its own pros and cons.
Which is more affordable to use , depends on the situation.

You are right, Centralized exchange is good, but it has no fiat pair.
You can trade your crypto asset to fiat there.

Which one do you prefer, centralization or decentralization?
I prefer both

Decentralized is much better if the admin doesn't care to know their costumers. Centralized is much better if the admin are to strict and more concern about to know their costumers. Both are good base on particular place and culture. It is also good if both are combined to serve much better tracking.

Decentralized and Centralized I think both share different rules which may be applicable to the project which they embark on even though one is more preferably to easily accessible by people without long process which is decentralized.
