I disagree with removing those with more invested. They are risking more, thus have a higher reward.
If you want to increase the odds for those with less to invest, the fairer proposal would be to allow people to pool their entries and then split the winnings.
1 whale with 300 tickets = 300 individuals with one ticket each
The whale gets all their reward because they are putting up all the risk. The pool of individuals share their reward because they are sharing the risk.
Exclusion under the guise of fairness is rarely fair.
