what concerns me also since longer time is #1 delegate thepool.io. Their acutally 75% share sounds fair, but their 0.2 Lisk payout threshold is such stupid. As smaller voter, I get average payouts of ~0.25 Lisk, but each time 0.10 Lisk network fee will be deducted.
Update: it looks like thepool.io just increased their payout threshold from 0.2 to 1.0 Lisk.
Thats good to see, even that the "voice" of us voters find more and more open ears.
So keep posting here your concerns with delegates, guys.
