Although there have both similar in word finances, they are also different in perspectives. As decentralized finance is not being manipulated nor control by a single person, unlike with cefi or centralized finance. In other words, they are opposite idea that conquering the world of crypto. It is a threat for centralized finance since decentralized have the most valuable term in crypto. We love decentralization because government and bank sucks.
not just simillar in the word finance but also simillar on how finance works except to thier system of course because one if centralize and the other is decentralize . you already explain above how these two system works but the overall of object of the cefi and defi are i think still the same .
to be honest i didnt knew that there are cefi too but cefi are those latoken and other ( i forgot ) that are related to lending ? because that is the first thing that came to my mind when i read the word finance . cefi are first to rise they didnt bloom as big as defi but there are still cefi till now but the question is if defi will also remain when the hype was over .
