# Level up Costs
Players can level up their CAThletes by **gaining the required amount of ****Gems** by walking (the conversion rate is *1000 steps : 1 Gem*, increased with the *Gem Multiplier* applied), and paying a certain amount of **$WLKN** per level-up.
Gems are no token, they can not be traded, sold, bought, transfered, or staked.
$WLKN are gained by winning competitions and can by bought on *Bybit, Huobi, Gate.io and AscendEX* exhanges.
A certain level must be achieved before the next Competition League is unlocked. Each level-up is followed each of the 3 stats increasing by 10% of their genetic maximum.
**First, use Gems to fill in the level progress bar:**
* Tap CAThletes (on the tap bar at the bottom of the screen);
* Select a CAThlete you’d like to upgrade;
* Scroll down to the level progress bar;
* Press ‘+’ button and select the amount of Gems you’d like to add to the progress bar.
\
Once there’s enough Gems, the ‘+’ button will turn orange, with an upward arrow. Press the orange level-up button, and if you have the **$WLKN** required to complete the level-up, press the button to level-up.
