# Purchase a Mining Pass

A mining pass allows users to join and participate in larger boosts to earn more points. There are 10 tiers of mining passes which range from free to 100 USDC at the beginning of the season. \

**Decay model:** After the first week(7 days) the price of all tiers drops by 25%. After the second week (14 days) the passes are discounted at another 25% (50% in total). \
\
This price decay was requested by the community ([https://vapordex.featurebase.app/](https://vapordex.featurebase.app/)) and is meant to encourage users to deposit VPND mid-season since points are determined by the number of days left in the season. This is subject to change as we see how the community feels about the current ranges of mining pass. This change would be voted on via a governance vote from the community.
