Trading - you take profits from all "betting" both games- just a little from each- but importantly loss smaller than any gains= right call on game pick!
For example lets say you boil it dow and "odds" are that it should be choice one-
Your trading and seeing that many people are taking choice one and its going against them= I sell
you can make real time choice while its unfolding- and cover at break even if it turns back to the odds...
