# Stats and Earn Rate

## Stats

Each Catto NFT has two types of stats: 

* **Static Stats** are fixed.
* **Generated Stats** are computed from static stats and other NFT properties.

### Static Stats

**Smartness\[S]:** Smartness impacts the daily reward cap.

**Vitality \[V]:** Vitality impacts stamina consumption.

**Dexterity \[D]:** Dexterity impacts earning speed.

**Curiosity \[C]:** Curiosity impacts the rate of experience accumulation.

**Luck \[L]:** Luck may impact places related to probability.

#### Static Stats Value Range

When a Catto NFT is minted, static stats will be assigned a value within a range that depends on the NFT Tier. All three static stats share the same value ranges based on the NFT Tier.

| Tier   | Min Stat Value | Max Stat Value |
| ------ | -------------- | -------------- |
| Tier 1 | 3              | 8              |
| Tier 2 | 8              | 16             |
| Tier 3 | 16             | 28             |

### Generated Stats

**Daily Reward Cap**

There is a daily reward cap for each Catto NFT, which is computed from the following formula:

**Stamina Consumption**

For every true-reading minute users spend on ReadON, equipped pets will consume stamina.  The amount of stamina consumed per minute is computed from the following formula:

**Earning Speed**

For every true-reading minute users spend on ReadON, they will accumulate $READ, up to the daily earning cap of the Catto.

#### Rate of Experience Accumulation&#x20;

For every true-reading minute users spend on ReadON until the daily reward cap is met, the equipped Catto NFT will accumulate experience (EXP). The amount of EXP per minute is computed based on the following formula.

## **Multiple** Catto **NFT Stacking**

For users with multiple Catto NFTs, only one pair can be equipped at a time as the Primary NFT. All other pairs of Catto will be displayed in the user’s inventory and will accumulate $READ and EXP at the reduced rate shown below.

| Number of NFTs in the inventory | Reduced Ratio |
| ------------------------------- | ------------- |
| 2-3                             | 0.7           |
| 4-7                             | 0.5           |
| 8-11                            | 0.3           |
| 12-15                           | 0.15          |
| 16+                             | 0.1           |
