# 7.8 EVT Excavation Caps

EVT is not designed to be excavated without limits.\
How much EVT you can excavate each month is naturally determined by your **BIND cap** and your **earning efficiency**.

***

### What you’ll learn on this page

* How to understand your monthly EVT excavation cap
* Monthly BIND limits by Trust Rank

***

### 1) How Monthly EVT Excavation Is Determined

In general, the amount of EVT you can excavate per month can be approximated by the following formula:

**Monthly EVT ≈ Monthly Eligible BIND Amount × Earn Rate × (Various Modifiers)**

*Note: The formula above is a simplified model intended to explain the monthly estimation concept.*\
The actual amount is calculated by applying the full set of modifiers described in [**5.3 Reward Formula**.](/rewards/formula.md)

The key point is that there is no fixed “monthly EVT cap.”\
Your monthly EVT amount is **naturally determined by your activity level and earning efficiency**.

***

### 2) Monthly eligible BIND amount (cap)

The eligible BIND amount has a monthly limit based on your Trust Rank.\
This limit is designed to support ecosystem health and prevent abuse.

#### Monthly BIND limits (by Trust Rank)

| Rank | Monthly BIND Limit (USD) |
| ---- | -----------------------: |
| S    |                    3,000 |
| A    |                    2,000 |
| B    |                    1,500 |
| C    |                      900 |
| D    |                      450 |

*For details on Trust Rank, please refer to Chapter 8.*

### 💡 Key point: A “natural cap,” not a fixed cap

EVT is not restricted by a fixed rule like:\
“You can earn at most X EVT this month.”

Instead, a natural cap is formed through:

**BIND cap × Earn Rate × various modifiers**

This means your excavation efficiency can improve as you:

* BIND more (within your eligible cap)
* grow your MANEKINEKO
* increase your parameters

***

### Summary

Your monthly EVT excavation amount is determined by the combination of:

* monthly BIND limits based on Trust Rank
* your MANEKINEKO progression (earning efficiency)
* various modifiers

EVT is not a simple “fixed-cap token.”\
It is designed so that earning efficiency changes in sync with **participation and progression**.
