## Travel Cashback

Travel cashback is earned on hotel bookings through GoMining Travel. The cashback rate depends on the user's VIP level.

### Travel Cashback Rates (TH/s by VIP Level)

| VIP Level | Cashback Rate |
|-----------|---------------|
| **Bronze** | 1% |
| **Silver** | 1.6% |
| **Gold** | 2.2% |
| **Platinum** | 2.8% |
| **Diamond** | 3.4% |
| **Legend** | 4.0% |

### Travel Cashback Formula

```
TH/s Cashback = Booking Amount (USD) x VIP Cashback Rate / Cost per 1 TH/s
```

| Parameter | Value |
|-----------|-------|
| Cost per 1 TH/s | ~$25 (approximate, subject to change) |

**Example Calculation:**

| Step | Value |
|------|-------|
| Booking amount | $500 USD |
| VIP level | Gold (2.2%) |
| Cashback value | $500 x 2.2% = $11 |
| TH/s awarded | $11 / $25 = **0.44 TH/s** |

### Travel Cashback Rules

| Rule | Details |
|------|---------|
| Eligible bookings | Hotels only (flights not included initially) |
| Accrual timing | Accrues after booking is confirmed |
| Finalization | Finalizes after guest check-out |
| Cancellation | Cashback reversed if booking is cancelled before check-out |
| Currency | Calculated and applied in TH/s |

### Travel Cashback Timeline

```
Booking Confirmed  ──>  Cashback Accrues (pending)  ──>  Check-Out  ──>  Cashback Finalized
```

> **Note:** If a booking is cancelled before check-out, the pending cashback is reversed.

## Miner Selection

A single miner is selected to receive all cashback from both Cards and Travel sources. The system handles miner selection automatically with manual override available.

### Auto-Selection Logic

| Priority | Rule |
|----------|------|
| 1st | Previously used miner (if still eligible) |
| 2nd | Strongest eligible miner |

### Miner Eligibility Restrictions

The following miners **cannot** be selected for cashback:

| Restriction | Description |
|-------------|-------------|
| **Installment miners** | Miners purchased via installment plan |
| **Miners on sale** | Miners currently listed for sale |
| **Low efficiency miners** | Miners with less than 20 wt/th |
| **Bonus miners** | Miners received as promotional bonuses |

### Accumulation Limits

| Limit | Value |
|-------|-------|
| **Max TH per miner** | 5,000 TH |

> **Warning:** Once a miner reaches the 5,000 TH cap, no additional cashback can be applied to it. The user must select a different eligible miner to continue receiving cashback.

## Frequently Asked Questions

### What is GoMining cashback?

GoMining cashback is a reward system that converts a percentage of your Card spending and Travel bookings into TH/s (mining power), which is applied as an upgrade to your selected miner.

### Is cashback the same for Cards and Travel?

No. Cards and Travel have different cashback rate tables. Travel rates are generally higher (1%-4%) compared to Card rates (0.5%-5%), though Card Legend level (5%) exceeds Travel Legend level (4%).

### How is cashback calculated for Travel bookings?

Travel cashback uses the formula: Booking Amount (USD) x VIP Cashback Rate / Cost per 1 TH/s (~$25). For example, a $500 booking at Gold VIP (2.2%) yields $11 / $25 = 0.44 TH/s.

### Can I receive cashback as tokens or fiat?

No. All cashback is delivered exclusively as TH/s mining power upgrades to your selected miner.

### How do I select which miner receives cashback?

The system auto-selects your previously used miner or your strongest eligible miner. You can manually change the selection. The same miner is used for both Card and Travel cashback.

### Why can't I select a specific miner?

Certain miners are ineligible: installment miners, miners listed for sale, miners with less than 20 wt/th efficiency, and bonus miners. Ensure your chosen miner meets all eligibility criteria.

### What happens when my miner reaches 5,000 TH?

Once a miner hits the 5,000 TH accumulation cap, no further cashback can be applied to it. You must select a different eligible miner to continue receiving cashback rewards.

### When does Travel cashback finalize?

Travel cashback accrues when the booking is confirmed but only finalizes after the guest completes check-out. If the booking is cancelled before check-out, the pending cashback is reversed.

### Do flights earn Travel cashback?

Not initially. Travel cashback currently applies to hotel bookings only. Flight cashback may be added in the future.

### How often does Card cashback accrue?

Card cashback accrues daily based on successful transactions from the previous period. Failed or reversed transactions do not generate cashback.
