So, i agree and dis agree with the bidding system. This Idea makes it a little more fair. So what it is, if your make it to a round you lose the tokens from the previous round, however you can still get the tokens from the round that you are in if you lose the auction, but don't advance to the next round
Round one (Bet 2 tokens advanced to round 2)
(Round one tokens don't get refunded since your advanced)
Round two (Bet 3 tokens, but didn't advance to round 3)
Round 3( Did not make it to this round, but your received the tokens from round 2 back
Since you didn't advance to round three you get the 3 tokens from round two back from you.
I think this is a fair way with bids, for every one.
Let me know what you think.
