# Cards/Polls Trading The pricing of cards/polls is tied to a specific bonding curve, meaning the price increases as more cards/polls are purchased and decreases with sales. The bonding curve's design incentivizes early participation, if you are early to spot a rising star, you will earn from doing so! Additionally, this pricing structure enables members to predict how their transactions will impact prices. It also guarantees consistent liquidity on the platform since transactions are conducted with smart contracts, contrasting with traditional order book-based trading systems, users are therefore able to buy/sell against our pool at any time, avoiding liquidity problem.

### ⚛ Atomised Bonding Curve based on price ladder 🪜 Alpha Club's bonding curve design is special, it is designed to **lower minimum purchase unit** at laddered prices, so that users are able to purchase 0.1 or even 0.001 card/poll just to put their skin into the game. (e.g. buying 0.005 Hsaka's club card while enjoying similar % gain as those buying more cards, but less absolute gains). *Club owners can still gate contents based on amount of cards held.* At price level of 0.025 ETH, 0.2 ETH, and 1.5 ETH, the minimum buying unit of card decreases to 0.1 card, 0.01 card and 0.001 card respectively. * **Bonding Curve's Function =>** *f(price) = (supply^2)/14285.* * **Price** refers to the current ETH rate at which user can purchase the next card/poll. * **Supply** refers to the outstanding amount of card/poll that holders currently own. * **Example =>** Alex bought a card when there's a supply of 50, spending 0.1750 ETH. He then decided to sell the card when supply increased to 100 (representing rising popularity of the club), he **doesn't need to have a buyer**, he sells directly to the smart contract for 0.7 ETH, profiting a staggering 300%.
