That took me a minute but I think the rewards for staking are a % of BUDS for now & will change to add HIVE rewards soon as well as a new currency used to mint Joint NFTs.
I was wondering the same thing but right now I think its generating BUDS for myself at least like 20 or so a day for 7,000 BUDSX staked or owned. Here is the latest post ill have to research further to be certain.

As for #stashpass thanks for the feedback / support I sent the following NFT to your Weedcash(HIVE) wallet.
You can view buy or sell those here

I will likely do a follow-up post on Hashkings when I have figured the whole system out for now that's my best guess.
