Decreasing Payouts, Exprt opinion???

After the HardFork 19, there was sudden increase in steemit potential payouts 💰. But since then posts are decreasing in payout of approximately 30% untill now and continue.

For example @jesta is upvoting almost every post throught beta.chainbb.com at 0.05% which was showing 0.17$ in payouts, but after three days it now shows 0.12$.

I have some questions to the experts and going to some people so they may targeted directly and reply my post.

Potential payout we see on posts are converted values of the Steem or SBD we may earn? Does that Steem or SBD remain same?

If i was earning 1 SP on one of my posts, and it was showing potential payout of 2.15$, but now shows 1.60$, but i will still earn 1SP?

Potential value of posts is decreasing but potential earning in SP or Steem or SBD will remain same?
