I think that it's not just a matter of higher HBD APR on Polycub, it's more about having an HBD stable coin on completely another blockchain network! That's like having it on a new centralized exchange multiplied by 10!

Putting the HBD in savings on Hive, or adding liquidity on Polycub isn't a brainer at all like you said... And there is no wrong choice! The most important fact is that, in either way, it works for a benefit of HIVE and all Hivers!

I have picked this post on behalf of the @OurPick project and it will be highlighted in the next post!
