Hey, @abh12345.

re: witnesses are rewarded in SP

Really? It's been a while, but I thought I read otherwise. You would know, though. :) Which makes less sense to me. I will edit that, then.

Do other chains do this? Pay their block producers in staked tokens?

All I know is, whatever factors are lending themselves to downward pressure on STEEM still exists, so if paying out in the token and not its staked version would make downward pressure worse, well, then, I guess we see where all these tokens are going.

And yet, I look at other blockchains and wonder if they have staked versions. Does Bitcoin, Litecoin, Ethereum, etc., do all that at all?
