Root + Impact

Description

• Users deposit funds, pick a country and if the country the picked is the winner set by the owner, they win a share of the prize pool

• The issue here is that there's no restriction on the owner to not participate in the event, and given that the winner selection isnt random but handpicked by the owner, owner could join and event, pick a country of his choice and make it the winner and win shares

Risk

Likelihood:

• When owner joins the event and sets the country of their picking as the winner

  
  

Impact:

• Owner gets an unfair advantage, since a win is always guaranteed for them
