What you said is right, but most of the well-established companies are showing a lot of interest towards the Defi model, now we are getting higher percentages in Defi, in the coming days we won't see this much high prices because in order to survive Defi they need to reduce APY on what they are holding.
Where there's opportunity for fast and easy money, there's where the ants will go. Of course every blockchain company's going to Defi now, when they don't even realize Defi is Bitcoin and Bitcoin is the true Defi.
Another bubble waiting to pop, when the rally starts.
