# Token Generator Factor

In order to create a sustainable economy and increase the value of the $SYBL, it will always be more and more difficult to mint new token. Then earnings depends on the $$TPU$$, the Token Per Unit. $$TPU$$is a logarithmical function depending on the number already minted. **It is recalculated every month depending on the number of tokens already minted.**

$$TPU(m)$$for the month *m* is calculated like below:

$$
TPU(m)=TPU(m-1)\times \bigg( 1-\cfrac{Total , Minted}{Total,Supply}\bigg)
$$

​with **:** 

$$TPU(m-1)$$: Token Per Unit for the month *m-1*

$$Total , Minted$$*:* the number of tokens already minted at the time of calculation

$$Total,Supply$$: the number of tokens supplied for the community $$1.5 ,. ,10^9$$

$$TPU(0)=2$$
