Yeah, I am not suprised on the Dex volume decline since December 2021, on reason is because, as far as Dex platform are concerned, the Defi tokens hype gave Dex exchanges a big potential to experience boom since the last 3years. In my opinion, the Dex exchanges will continue to experience decline because many of the projects launched on exchanges could not continue to providing trading volumes especially when the market price of tokens goes down heavily.
