you must send at least 1 SBD

@patriot can you help how can i used booster and how much spd sent to booster and how much time in a day i used it?

Yes I can, you can send 1 SBD or more you should use it 24 hours after the last time @booster upvoted you because then you get better profits from the @frontrunners!

Also, This is from @booster:
bids open every 2.4 hours. Ex: @Axe & @Bob both bid for the same voting batch. If @Axe bids 4 SBD and @Bob bids 2 SBD, @Axe will get 66.66% and @Bob 33% etc.
