*What Are CoinEmpire NFTs?*

**Note**: [Click here for an overview of CoinEmpire game play](/0msPTtOkRsyQU4xoQoppyQ?both).
- CoinEmpire NFTs are collectable cards that allow players to generate additional income from their virtual real estate and earn passive income. There are three types of CoinEmpire NFTs: 

- Noble NFTs: These enable CoinEmpire land owners to prevent other players from buying their property for a period of time. They can also be used to improve properties. Improved properties can be sold to other players for higher prices. 

- Royal NFTs: Holders of these NFTs are eligible to potentially earn passive income from the CoinEmpire Royal Treasury. The Treasury is funded by a tax on all CoinEmpire economic activity (property buys, sells and improvements).

- Crafted NFTs: These are special cards that can be created by combining Noble and Royal cards in special combinations called recipes.

As outlined in the [CoinEmpire gameplay](/0msPTtOkRsyQU4xoQoppyQ?both) section of this whitepaper, CoinEmpire is a winner-take-all game, meaning that: 

- **One Owner Per Property**: Only one account is allowed to own an individual CoinEmpire real estate property at a time 

- **Only Property Owners Earn ETH Income**: ETH payouts are only delivered to the single owner of a CoinEmpire property. 

CoinEmpire NFTs add another layer of strategy (and earning potential) to the game. 

NFTs enable players to earn more income from their properties (by holding on to them longer, and improving them) and generate additional passive income from the CoinEmpire game economy. 

There are three categories of CoinEmpire NFTs: **Nobility**, **Royals** and **Crafted**. See the infographic below for an overview of the CoinEmpire NFT card deck.

CoinEmpire Nobles: Holding and Improving Real Estate to Earn Greater Income 
---


**Nobility NFTs** are for active virtual real estate speculators and those seeking higher potential income. They grant CoinEmpire property owners two benefits: 


- **Lock Real Estate**: Players can use Nobility NFTs to prevent other players from buying their CoinEmpire property. This can be especially useful if the property is (or could) generate additinal income. There are five different levels of Nobility NFTs, which allow players to lock land for longer periods of time. 

- **Improve Properties**: Nobility card holders can also improve real estate (there are five levels of improvements players can make). Owners of improved real estate can sell their properties to other players for higher earnings. Higher level Nobility cards allow for greater improvements, which provide players with additional earnings when their real estate is sold. 

**Nobility Card Cooldown Periods**

Nobility NFTs can be used unlimited times, but have a cooldown period that increases in length each time it is used. Information about the cooldown periods will be provided closer to the [CoinEmpire NFT Genesis Sale](/@decentribeTEAM/S1ypS6FLr), but the table below illustrates how it will work. 


| Times Nobility NFT Used | Sample (Not Final) Nobility NFT Cooldown Period |
| -------- | -------- | -------- |
| 1 Time     | 3 Hour Cooldown Per NFT  |
| 2 Times     | 6 Hour Cooldown Per NFT  |
| 3 Times     | 9 Hour Cooldown Per NFT  |
| 4+ Times     | Additional Cooldown Periods Per NFT  |

In the [CoinEmpire Genesis Sale](/@decentribeTEAM/S1ypS6FLr) chests will contain multiple Nobility cards so that players can stagger their use.

CoinEmpire Royals: Compete for a Share of the Royal Treasury
---

As discussed [previously](/0msPTtOkRsyQU4xoQoppyQ), CoinEmpire is similar to the real-world property market, where players can buy, earn from from and improve virtual real estate. 

Yet, in every real estate market, the government also plays a role by taxing real estate activity. 

CoinEmpire cities have their own government: Royals. 

Royals can compete to own special real estate type (Royal Domains) that gives them the right to collect a share of the Royal Treasury. The Treasury is funded by a tax on all CoinEmpire economic activity: buys, sells and property improvements. 

Players can hold Royal NFTs that entitle them to own a floor in the city's Royal Domain building. Owners of these properties can collect a share of ETH deposited into the Royal Treasury. 

However: 

- **Royal Domain Holders are Capped at 25 Accounts**: A maximum of twenty-five players will be eligible to collect ETH from the Royal Treasury during each 5-day ownership period. 

- **Ownership is Limited to a 5-day Period**: Owners are randomly selected from a pool of NFT holders (who stake their cards in a special contract). New Royal Domain owners are selected every five days.
 
- **Higher-Level Royal Cards Are Important**: Those owning higher-level cards have a greater chance of being selected for Royal Domain ownership. 

In summary, Royal NFT holders have the potential to earn passive income from CoinEmpire by: 

- Staking their NFTs

- Being selected for Royal Domain ownership

- Collecting a share of ETH deposited into the Royal Treasury 

Below are some scenarios regarding potential earnings for Royal NFT holders who own a Royal Domain real estate property. 

---

#### Potential Passive Income Earnings from the CoinEmpire Royal Treasury (During Each 5-Day Ownership Period)


| Total Potential ETH in Royal Treasury (Daily Deposits)  | Individual Share | Individual Earnings (Daily) | Individual Earnings (After 5 Days) 
| ---- | ------- | ----------- | ----------- | 
| 3 ETH  | 1/25 (4%)  | .12 ETH         | .6 ETH |
| 15 ETH  | 1/25 (4%)  | .6 ETH         | 3 ETH |
| 45 ETH  | 1/25 (4%)  | 1.8 ETH        | 9 ETH |

*Note: The figures presented above are for illustration purposes only. The Decentribe team does not guarantee any player will earn the amount of ETH referenced in the table above from collecting a share of ETH deposited into the CoinEmpire Royal Treasury.*

**Royalty Card Cooldown Periods**

Royalty NFTs can be used unlimited times, but have a cooldown period that increases in length each time it is used. Information about the cooldown periods will be provided closer to the [CoinEmpire NFT Genesis Sale](/@decentribeTEAM/S1ypS6FLr), but the table below illustrates how it will work. 


| Times Royal NFT Used | Sample (Not Final) Royal NFT Cooldown Period |
| -------- | -------- | -------- |
| 1 Time     | 3 Day Cooldown Per NFT  |
| 2 Times     | 6 Day Cooldown Per NFT  |
| 3 Times     | 9 Day Cooldown Per NFT  |
| 4+ Times     | Additional Cooldown Periods Per NFT  |

In the [CoinEmpire Genesis Sale](/@decentribeTEAM/S1ypS6FLr) chests will contain multiple Royalty NFTs so that players can stagger their use. 

++Royal NFT Listing++

| NFT Rarity and Name | NFT Power (Chance of Selection for Royal Treasury is Preliminary and Not Final) |
| -------- | -------- | -------- |
| Rare: Ruby Emperor     | After Card is Staked, NFT Holder Has 5% Chance of Being Selected to Own a Royal Domain and Receive a Share of the Royal Treasury |
| Epic: Sapphire Empress | After Card is Staked, NFT Holder Has 10% Chance of Being Selected to Own a Royal Domain and Receive a Share of the Royal Treasury |
| Legendary: Emerald Fool | After Card is Staked, NFT Holder Has 15% Chance of Being Selected to Own a Royal Domain and Receive a Share of the Royal Treasury |
| Secret: Diamond Bastard| NFT Holder Can Play This Card to Gain a 8% Chance of Replacing Any Current Royal Domain Occupant (Note: These players will be removed from Royal Domain ownership afer the standard five-day holding period) |

CoinEmpire cards are designed to appeal to both players and collectors. 

* **"Mint" cards will be more valuable**: Each time a card is used, the card's cooldown period will increase. This means that over, time, cards that have not been used (cards in mint condition) could become more valuable as fewer cards with lower cooldown periods are available for use or trading 

* **More rare cards have a higher value in-game and for collectors** There will be fewer higher level cards minted, making them potentially more sought after by players and collectors. 

We anticipate that rarer cards in mint condition will have a higher re-sell value over time. 

Crafted CoinEmpire NFTs
---


**Crafting: Turning Used CoinEmpire Cards into New NFT Assets**

CoinEmpire NFTs can also be combined using recipes that enable two special cards to be developed:

* **EVICT = Secret + Non-Mint Lower Level Nobility Cards**: These can be combined to create an "Evict" card that allows players to evict others from land they hold 

* **HODL = Secret + Non-Mint Lower Level Royal Cards**: These can be combined to create a "Hodl" card that prevents others from evicting them from a Royal Domain property (using a Diamond Bastard card)

Crafting will add another strategy element to the game and help to maintain the value of non-mint cards (cards that have been used in-game and have longer cooldown periods).

**Card Rarity Levels, Benefits and Crafting**

| Card Rarity Levels | Benefits| Crafting|
| -------- | -------- | -------- |
| **Nobility Cards**: Rare, Epic, Legendary, Ultra Legendary, Secret    | Each level allows a property to be held for a longer time period and higher-level property improvements | Secret cards can be combined with non-mint lower-level Nobility cards (cards that have been used in-game) to create an "Evict" card that allows players to remove others from CoinEmpire properties they are holding. **Sample (Not Final) Crafting  Recipe**: Used Rare Card + Used Epic Card + Secret Card (Mint or Used) = Evict Card   
| **Royalty Cards**: Rare, Epic, Legendary, Secret | Higher card levels increase the odds the holder will be selected to earn a share of the Royal Treasury every five days | Secret cards can be combined with non-mint lower level Royalty cards (cards that have been used in-game) to create a special "Hold" card that prevents Diamond Bastard holders from evicting them from a Royal Domain property. **Sample (Not Final) Crafting  Recipe**: Used Epic Card + Used Legendary Card + Secret Card (Mint or Used) = Hodl Card  |  |
