I read yesterday the article it is nice. I see many benefits in there. 1st giving the option of liquid staking for the used and maybe use HBD to other DEFI actions, maybe LPs and borrowing HBD for example. This way the user get something on top of the HBD APR and in addition it creates a bigger utility of HBD in the chain. There are many critics of the HBD savings saying that it doesn't help anything the blockchain (which I disagree ).
