title_body: Can the max supply of ADA be decreased or burned? would decrease the amount of the max supply of ADA tokens?
  With the limited supply, it can build more demand and that might be benefit for the team and also the investors.
upvoted_answer: Decreasing the supply is a method to artificially raise the value of the remaining supply.  It has been repeatedly stated that all ADA has an owner/purpose and supply will not be reduced.  ADA relies on use and utility to increase its value.
