# For Investors

CannaCards have a built in demand and a controlled supply to influence rarity and volatility, which creates unique opportunities for users to trade their cards for profit.&#x20;

### Supply: Card Rarities and Burning

CannaCards have a natural sense of rarity to them due to the nature of how they are minted and upgraded. (View this article for minting information: <https://www.cannabisbuiltdifferently.com/post/minting>)

Silver, Gold, and Platinum can only enter circulation via an upgrade. When CannaCards are upgraded, two of the original ranked cards are burned and replaced with just one card of the next rank. This means upgrading card makes all other cards of the original ranking more rare.&#x20;

### Demand: Utility

CannaCards have a built in utility in that they are a required piece to play a video game. Anyone who has an interest in playing the video game will have an interest in collecting as many cards as they can.&#x20;
