Stakes allow you to get a proportion of the total coins available for a certain bounty.
Example:
- 10 stakes earned by you / 10000 total stakes earned by the community = 0.001 % of total stakes earned by you
- Let's say 10,000,000 coins are available for the bounty you participated in, you would get 0.001 % of 10,000,000 = 10,000
