Cost arbitration
A strategy that is rarely used in Brazil, but which can give great results according to my experience in consultancy, is being able to use different sources to minimize costs.
A classic example is electricity and gas. Looking at a more "expanded" horizon, significant savings can be made by making this "arbitration".
Or even maintain productive activity in times when energy supply is experiencing challenges (rationing, for example).
This alternative is interesting for those who like to be prepared (well in advance) for real market situations. Contrary to most in the heat of events!
