> crypto is built to change the people that control the money

Yep, crypto is a revolution being staged to replace the establishment (central banks and traditional finance) with a new one (crypto/defi founders and adopters). The goal is to use the new marketing to draw people to the new system and become the new rich. The earlier and more you buy into it, the more incentive you have to spread the word.

This is why it makes sense to rebuild everything in crypto despite it being less efficient. It needs to be done, so that the new system (that replaces all parts of the old) is ready for people to be drawn into it.
