Hey there,
regarding @smartsteem's payout and why it's displayed as 0%:
With recent changes, delegators profit is being credited to the users' Smartsteem balance. This balance can be either withdrawn manually or paid out automatically (if enabled) if it's above a certain threshold. The threshold is currently at 0.7 SBD / STEEM.
In @wefund's case: the daily revenue is not enough to reach 0.7 SBD / STEEM every day. That's why it's displayed as 0%.
For now, the threshold is here to prevent double-spending and currently at 0.7 due to thousand of users delegating & selling votes.
But rest assured: a solution is being worked on.
