XP is the central progression metric. It feeds the user level curve and the USBI entitlement formula.

​
Core formula

total_xp = total_crs_spent
Every Crystal (CRS) you spend in the Bini App produces exactly one XP. There is no multiplier, no loss, no exception.

​
Cap

max_xp = 1,000,000,000  (capped at Level 30)
Once you have spent 1B CRS, you are at Level 30 (Genesis) and your XP no longer counts for level progression. The cap exists so the level system has a clear endpoint and the maximum USBI entitlement is defined.

​
What counts as CRS spend

Every action that consumes CRS gives XP:
ActionGives XP
Lesson upgradeYes
USBI bridge (Bridge A)Yes — 10,000 CRS spent = 10,000 XP earned
SkinsYes
Lottery ticket (CRS-priced)Yes
Agent Token spawn (CRS portion)Yes
Token boost / promotionYes
Other CRS sinksYes
Earning CRS (mining, claims, daily calendar, referrals) does not earn XP. Only spending does.

​
Why “spend” not “earn”

The model rewards engagement and risk-taking, not passive accumulation. Hoarding CRS doesn’t level you up. You must commit your CRS to a sink for XP to flow. This also means there’s no incentive to farm-and-hold — the optimal strategy is consistent spending into productive sinks (lessons first, bridges and other sinks later).

​
Formula in code

For implementers: 
function totalXp(totalCrsSpent) {
  return Math.min(totalCrsSpent, 1_000_000_000);
}

USBI Formula

XP → USBI entitlement
