<figure><img src="/files/8BNPwSBNppNeiORVhZ6M" alt=""><figcaption></figcaption></figure>

{% hint style="warning" %}
This is a side project on Cardano from 2025.&#x20;

Essence Crystals are available on secondary markets or open a ticket in our Discord if you want to purchase more - we still have some in the reserve to expand the operation from time to time
{% endhint %}

## 🔥Real passive income through crypto mining,

NFTs that earn for you every month: that's what Essence Crystals are about

## 💰Miner NFTs with the highest APR around&#x20;

\- Not your casual crypto mining NFTs as we invest in alt-coins and trying to minimize the risks of a very risky area&#x20;

\- Low total supply to maintin high APR&#x20;

\- Purchased miners purchased through are the most efficient ones: best electricity and mined coins

## 🧠Carefully designed system for long-term passive income&#x20;

\- 90% of profits goes back to the operation (70% to holders, 20% for a repair & reinvestment reserve)&#x20;

\- New miners are coming in the bear, while they are cheaper&#x20;

\- Best distributor - hosting service provider - efficiency combination available&#x20;

### ⚒️Miner choices

Currently our mining operation includes

* 1 Antminer L9s (17GH) - $DOGE, $LTC
* 2 Iceriver AE 2 (720 Mh) - $ALEO
* 3 IceRiver AE 1 Light (300 Mh) - $ALEO
* 1 Goldshell XT-BOX (580 Gh) - $XTM
* 3 Bitaxe Gamma 601s solo BTC miners to win big (very low chance for 3.125 BTC)

These are among the most efficient miners for the lowest j/Mh rate.

Meaningful passive income for years.\
That's what Essence Crystals are about.
