Until further notice I'm giving a 100% upvote from @perfilbrasil on every reply posted by whoever delegates 100 HP to @perfilbrasil for at least a week.
Or 200HP for minimum of 3.5 days.
Or 700 HP for 24 hours.
Or 1400 HP for 12 hours.
Or 2800 HP for 6 hours.
You got the math.
You can also always claim your share using via https://hivetasks.com/perfilbrasil.
To know if you qualify for the automatic upvote, just check if the "Free Exchange" column of your delegation is already above 100 Hive.
Transaction processing of withdraws is done by KeyChain, BTW.
