Explanation:

• Base Buy-In: Participants who buy in at the base level of 5m are eligible for the standard prize pool distribution (50% for 1st place, 30% for 2nd place, 20% for 3rd place) without any additional modifiers.
  
• Level 2 Buy-In: Participants who choose to buy in at 10m get a 10% increase in their prize money. For example, if they win 1st place, they would receive 50% of the prize pool plus an additional 10% of that amount.
  
• Level 3 Buy-In: Participants who buy in at 50m get a 25% increase in their prize money. This higher buy-in level provides a more substantial reward for those willing to invest more.
  
• Level 4 Buy-In: Participants who buy in at 100m get a 40% increase in their prize money. This is the highest buy-in level, offering the largest reward modifier for those taking the biggest risk.

Considerations:

• Balance: The percentages are designed to provide a clear incentive for higher buy-ins while ensuring that the base buy-in remains attractive for those who prefer a lower risk.
  
• Fairness: The reward modifiers are proportional to the buy-in amount, ensuring that participants feel their investment is worthwhile.
  
• Sustainability: The structure should be sustainable for future events, encouraging participants to engage in the long term.
