Button Game

Wallet restrictions are easily circumvented with burners

Anything with the website can be circumvented by calling contract functions directly

It has to be botproof on the contract level

something like scaling cost to press the button, or a different method of distributing the pot besides winner-take-all, possibly based on either how much time was spent as the current winner or ranking by average length of time being the current winner per button press

I kept rewriting this post with ideas, and kept deleting it as I came up with ways to exploit what I had just written 

Avg length of time winning per press is easy to bot by pushing only on daily activity lows, for example

Tough one to crack

Make someone do a math problem/puzzle/type letters everytime they click the button?
