# Drink Water
Stay hydrated — stay rewarded.\
The **Drink Water Card** reminds you to take regular water breaks and rewards you with $DONE tokens every 4 hours.
***
### ⚙️ How It Works
Once you’ve acquired this card:
1. Go to your **Cards** section.
2. Find the **Drink Water Card** and move it to your **Active Card Area** (requires a free card slot).
3. Once activated, a **4-hour countdown** begins.
During that time, make sure to drink **at least one glass of water**.\
When the timer completes, return to the app and claim your reward.
> 💦 *Your hydration habit just became productive.*
After claiming, the timer automatically resets — starting the next 4-hour cycle.
***
### 💎 Card Levels & Rewards
The **Drink Water Card** comes in 4 levels.\
Higher levels yield more $DONE tokens per cycle.
| **Card** | **Card Level** | **Reward per 4h** | **Cycle Reset** |
| :------------------------------: | :------------: | :---------------: | --------------- |
|  | Lv.1 | 50 $DONE | 4 hours |

### 🔄 Managing Your Card
* You can deactivate the card anytime in **My Cards → Active Cards**.
* Removed cards remain in your App Wallet until reused or sold.

### 💰 Selling Your Card
When listing for sale:
