Auction simulation

How scenarios work

• Auction tier — pick a card in the tiers below; it sets the funding goal and clearing schedule: Blitz runs 240 one-minute periods, Starter runs 24 hourly periods, and Verified and Premium run 72 hourly periods. On the Premium card, pick a goal — each goal has its own fee and team-bonus split.
• Approx. bidders — how many generated bids enter the auction. Total committed demand comes to about 1.5× the funding goal, split across the bidders.
• Highest bid — the largest single bid budget in GRAM; the rest scale down from it, so most generated bids are smaller.
• Demand pattern — where generated bids land across the clearing schedule: steady spreads evenly, front-loaded arrives early, back-loaded late, whale-heavy mixes many small bids with a few large late bids, and random is seeded-random arrival.
• Adaptive bidding — generated bidders react to price action like real users: limit bids priced out by a rising clearing may place a follow-up bid higher, and late bids meet the current minimum instead of failing.
