The money will be given to 3 voters, randomly choosen
I will use https://www.random.org/ to choose the winner.
Imagine a user with a big voting power upvotes this post with 100% and 9 users with small voting powers also upvote the post 100%(the voting power is divided in vests, let's imagine the first user upvotes it with 15 million vests and the other 9 upvote it with 1 million votes each...the post has a total votes of 24 million. So, I will use random.org to do the lottery. The user that upvoted with the more voting power will have 15 chances in 24 in each of the 3 times, the others 1 in 24 in once of the 3 times . But if one of the small voters win, will benefit from the SBDs generated by the fat vote of the big voter.
SO, THE STRONGER YOUR UPVOTE, MORE CHANCES YOU HAVE TO WIN ALL THE MONEY
