It's NOT a Giveaway ! It's a Contest, you win HBD only if you get at least ONE of the LOTTO numbers correct!
Have you ever played a LOTTERY in real life? Do you get your "Lottery ticket" for FREE ?
There is no Minimum amount of upvote, that's your choice! @dlmmqb
That's not how hive upvotes work. Your can't make a rule to participate in any giveaway or Lottery.
Reward pool is not for any lottery participation by making it a rule "upvote to participate".
