at their Lisk address you can see that they transfer 170 Lisk each day to Robinhood
https://explorer.lisk.io/address/13112651512533400586LSo this will be charged there I guess.
I also had expected a bit more earnings, but 170 Lisk splitted by so many voters unfortunally isn't that much.
it don't seems much but it's only for 3 of your votes, if all the over deleguates were paying as much as the sherwood team, Lisk Dpos will be one of the best Pos coin out there.
the problema actually are team like elite lisk asking you to vote for all their deleguates (some of them being outside of the top 101) to get rewarded.
