# Space Beacon Coordinates Tools

## **Introduction**

* Space Beacon is a derivative product used to collect BNB Gems within the Mining Space.

## **Benefits**

* The redemption function of Space Beacons will be available in the future. Please stay tuned.

## **Types**

* Space Beacon is divided into 3 types, each with different benefits
  1. Copper Beacon
  2. Silver Beacon
  3. Gold Beacon

## **Reward Coefficient**

* Define the reward coefficient r for each purchase. The number of BNB Gems purchased each time is ***n\_B*** and the total number of BNB Gems in the current round is ***n\_L***. The algorithm for calculating the reward coefficient is as follows:
  1. ***r = 50\*n\_B/n\_L***
  2. ***If r < 1 , r = 1***
  3. ***Else if r > 3, r = 3***

## **Acquisition Methods**

* The number of Space Beacons obtained is calculated by multiplying the number of purchased BNB Gems by the reward coefficient. Among them, 20% is converted into Gold Beacons (5 quantity converts to 1 Gold Beacon, any quantity less than 5 will not be converted). After conversion, 30% is converted into Silver Beacons (2 quantity converts to 1 Silver Beacon, any quantity less than 2 will not be converted). The remaining 50% is converted into Copper Beacons. The algorithm is as follows:
  1. The quantity of Gold Beacons ***b\_G=0.2\* n\_B \*r / 5*** ，rounded down to the nearest integer
  2. The quantity of Silver Beacons ***b\_S=0.3\*（n\_B\*r-5\*b\_G）/ 2*** ，rounded down to the nearest integer
  3. The quantity of Copper Beacons ***b\_C=（n\_B\*r-5\*b\_G-2\*b\_S）\*0.5***，rounded down to the nearest integer
* When purchasing more than 2% of Gems in the current level at one time, you will receive an additional bonus, 6% will be the maximum limit. For example:
  1. For the first level, purchasing 10 BNB Gems accounts for 10%. In this case , you can obtain ***1 b\_G, 3 b\_S and 9 b\_C***
* As the percentage of each purchase decreases, it finally drops to below 2%, and when purchasing a quantity less than or equal to 2% at one time (when the reward coefficient r = 1), the examples below will apply:
  1. Purchasing more than 25 BNB Gems at one time can obtain Gold Beacon, while purchasing 25 BNB Gems can obtain:

     ***a.  Gold Beacon \* 1***

     ***b.  Silver Beacon \* 2***

     ***c.  Copper Beacon \* 8***
  2. Purchasing more than 7 BNB Gems at one time can obtain Silver Beacon, while purchasing 7 BNB Gems can obtain:

     ***a.  Silver Beacon \* 1***

     ***b.  Copper Beacon \* 2***
  3. Purchasing more than 2 BNB Gems at one time can obtain Copper Beacon.
