# MINING UNITS AND RANKS

Mining Units (miners) are the main engine of passive income within the Blood Sharks ecosystem.

***

### ⛏️ How purchasing works

<figure><img src="https://content.gitbook.com/content/jU9SIcWWfOKswzvV8adR/blobs/pN5XyC8ugeqpg3fyLl94/miner_rarity_tier_def.png" alt=""><figcaption><p>Miners rarity</p></figcaption></figure>

When you buy a Mining Unit, the rarity you receive is **random**, exactly like opening a surprise pack. You do not choose the rarity in advance: the system assigns the miner based on the official drop probabilities.\
\
This mechanism makes every purchase unique and adds an element of surprise, rewarding those who invest consistently over time.\
\
The cost is **500** `RUB`/miner

The mining machine does **not consume** battery, CPU or real resources. It is a graphic animation designed to make the interface more engaging and visual, while rewards are recorded within the platform.

**💰 Daily earnings by rarity**

Every miner generates `$USDC` every day automatically. The value depends on the rarity obtained.

| Rarity    | Base daily earnings |
| --------- | ------------------- |
| Common    | From $0.60/day      |
| Uncommon  | From $0.85/day      |
| Rare      | From $1.25/day      |
| Epic      | From $2.00/day      |
| Legendary | From $3.50/day      |

{% hint style="success" icon="percent" %}
The value shown is the base value. Each miner can be upgraded using rubies (`RUB`) up to a maximum of **+50% daily output**, divided into **10 levels** of **+5% each**.
{% endhint %}

### 📊 Drop probabilities

As shown in the table, every Mining Unit purchased is assigned a rarity randomly based on fixed percentages: the higher the rarity, the rarer the probability of obtaining it and the higher the daily earnings generated.

***

### **⏏️ Miner slots**

To host your miners you need slots. Each slot corresponds to one available space for an active miner.

* When you join the ecosystem you will start with **3 free slots.**
* You can purchase additional slots using your `RUB`&#x20;

By climbing the ranks you automatically unlock discounts on slot packages, up to **25%** at Diamond rank:

| Slot Package | Base Price | Bronze (-5%) | Silver (-8%) | Gold (-12%) | Platinum (-18%) | Diamond (-25%) |
| ------------ | ---------- | ------------ | ------------ | ----------- | --------------- | -------------- |
| 5 slots      | 20 `RUB`   | 19 `RUB`     | 18.4 `RUB`   | 17.6 `RUB`  | 16.4 `RUB`      | 15 `RUB`       |
| 8 slots      | 30 `RUB`   | 28.5 `RUB`   | 27.6 `RUB`   | 26.4 `RUB`  | 24.6 `RUB`      | 22.5 `RUB`     |
| 10 slots     | 35 `RUB`   | 33.25 `RUB`  | 32.2 `RUB`   | 30.8 `RUB`  | 28.7 `RUB`      | 26.25 `RUB`    |
| 20 slots     | 65 `RUB`   | 61.75 `RUB`  | 59.8 `RUB`   | 57.2 `RUB`  | 53.3 `RUB`      | 48.75 `RUB`    |

{% hint style="success" icon="square-plus" %}
You can also expand your capacity **for free** by climbing the ranks: each higher rank unlocks additional free slots.
{% endhint %}

### 🏅 Rank benefits, slots and much more

Climbing the ranks is not just a milestone: it brings concrete and permanent advantages within the ecosystem.

<figure><img src="https://content.gitbook.com/content/jU9SIcWWfOKswzvV8adR/blobs/GgvmwyjsWhSHKCNKkWKJ/rank_benefits_def.png" alt=""><figcaption><p>Rank benefits</p></figcaption></figure>

As shown in the table, depending on your rank you will gain increasingly powerful and tangible benefits within the Blood Sharks ecosystem.\
\
From **Bronze rank** onwards, staking rises from the base **6%** to **21% APY**, more than triple. Each higher rank adds free miner slots (from **+1 to +5**), **increases the claim percentage on direct referrals** (from **0.6%** at **Bronze** to **3.0%** at **Diamond**) and **boosts the luck bonus** across all games and leaderboards (from **+5%** to **+19%**).

{% hint style="info" icon="person-digging" %}
In summary: the higher you rise in rank, the more you earn passively, the harder your network works for you and the greater your advantage across every aspect of the app.
{% endhint %}

### 🪫 Wear, upgrades and fusion

Your miners are not static: they can **deteriorate** over time, **be upgraded** to perform better and **be fused together** to obtain higher rarities. Understanding these three mechanics is essential to **maximizing your earnings** within the Blood Sharks ecosystem.

<figure><img src="https://content.gitbook.com/content/jU9SIcWWfOKswzvV8adR/blobs/PyhIP8tvYqVZQWmFBKYJ/miner_durability_upgrade_def.png" alt=""><figcaption><p>Durability &#x26; Upgrades</p></figcaption></figure>

Every miner has a **lifespan expressed in days.** Once that period has elapsed, the miner deactivates and stops generating `$USDC` until it is reactivated.

### **🔋 Reactivation**

When a miner reaches the end of its cycle, you can reactivate it by paying a fee in `RUB`:

* Reactivation cost: **75** `RUB` (for all rarities except Legendary)
* Reactivation restores the miner to **100% durability**
* All **applied upgrades are preserved**
* The **rarity remains unchanged**

{% hint style="success" icon="battery-full" %}
**Legendary miners** never wear out and require no reactivation: they are the longest-lasting and most profitable investment in the ecosystem.
{% endhint %}

***

### ⚡ Upgrades

Each miner can be upgraded up to **10 levels,** with a **+5% increase** in daily output per level reached. At the maximum level your miner will produce **+50% more** than its base value.\
Upgrades are paid in rubies (`RUB`) and the cost increases with each level:

<table data-search="false"><thead><tr><th>Level</th><th>Cost in rubies</th><th>Total boost</th></tr></thead><tbody><tr><td>LVL 1</td><td>20 <code>RUB</code></td><td>+5%</td></tr><tr><td>LVL 2</td><td>35 <code>RUB</code></td><td>+10%</td></tr><tr><td>LVL 3</td><td>55 <code>RUB</code></td><td>+15%</td></tr><tr><td>LVL 4</td><td>80 <code>RUB</code></td><td>+20%</td></tr><tr><td>LVL 5</td><td>110 <code>RUB</code></td><td>+25%</td></tr><tr><td>LVL 6</td><td>150 <code>RUB</code></td><td>+30%</td></tr><tr><td>LVL 7</td><td>200 <code>RUB</code></td><td>+35%</td></tr><tr><td>LVL 8</td><td>270 <code>RUB</code></td><td>+40%</td></tr><tr><td>LVL 9</td><td>350 <code>RUB</code></td><td>+45%</td></tr><tr><td>LVL 10</td><td>450 <code>RUB</code></td><td>+50%</td></tr></tbody></table>

Practical example: a **Common** miner with a base earning of **$0.60/day,** brought to level **10,** will generate **$0.90/day** **(+50%).**

{% hint style="success" icon="bolt-lightning" %}
Upgrades **survive reactivation:** even after a miner has worn out and is reactivated, all upgrade levels remain active.
{% endhint %}

### **🔀 Miner Fusion**

Fusion allows you to combine **three miners of the same rarity** to obtain a **miner of a higher rarity.** It is the most direct way to scale the quality of your miner fleet without relying solely on the randomness of purchases.

<figure><img src="https://content.gitbook.com/content/jU9SIcWWfOKswzvV8adR/blobs/DQ9ADzYivQKlgcbtL44F/miner_fusion_def.png" alt=""><figcaption><p>Miner fusion</p></figcaption></figure>

### **⚠️ In case of failure**

Fusion is not guaranteed. If the process fails:

* The **3 miners** used are permanently destroyed
* The `RUB` **fee** is fully refunded
* The **Refund Wheel** activates: spin it to recover part of your investment:

| Prize               | Probability |
| ------------------- | ----------- |
| 0 `RUB`             | 55%         |
| 10 `RUB`            | 25%         |
| 40 `RUB`            | 15%         |
| 80 `RUB`            | 4%          |
| 200 `RUB` (Jackpot) | 1%          |

### **💡 Strategic tips**

Before fusing, consider whether the miners you are sacrificing have active upgrades: **upgrades transfer to the resulting miner**.\
High-rarity fusions (Epic to Legendary) have a **40% success rate**: proceed only when you are ready to accept the risk.\
Accumulate `RUB` consistently through missions and games to sustain fusion and upgrade costs without affecting your cashflow.

### **🚀 Why invest in miners**

* Generate **real passive income** in `$USDC`, proportional to your commitment.
* Access **exclusive missions, events and prizes** reserved for active miners.
* Become part of a **selected community** in the world of crypto and NFTs.
* Build a **meritocratic** and **sustainable** path over time.

{% hint style="success" icon="chart-pyramid" %}
**Blood Sharks is not a pyramid scheme.**\
Every reward is directly linked to personal activity and referrals made, not to second-level or derivative referrals.\
The goal is to build a sustainable ecosystem based on participation, transparency and real value.
